PAMELA BROWN, CNN HOST: Your next hour of CNN NEWSROOM starts right now.

(BEGIN VIDEO CLIP)

UNIDENTIFIED MALE: They decided to raise the city to the ground. The city doesn't exist anymore. Mariupol may be a red line.

UNIDENTIFIED MALE: He thinks the war is necessary. I think he believes he is winning the war.

VOLODYMYR ZELENSKYY, UKRAINIAN PRESIDENT (through translation): Ukraine in the people of our state are absolutely clear. We don't want anyone else's territory and we are not going to give up our own.

UNIDENTIFIED MALE: The call came in from multiple shots fired. And I'm talking over 90 rounds and the two victims from gunshot wounds die. Those under the age of 18.

UNIDENTIFIED FEMALE: 14 people were injured at a mall shooting in Columbia, South Carolina. Many people were lined up to get their pictures taken with the Easter Bunny.

UNIDENTIFIED FEMALE: Connerjack Oswalt was reported missing by the Clearlake Police Department on Sep. 29, 2019.

UNIDENTIFIED MALE: He's like you're shivering cold.

UNIDENTIFIED MALE: The missing person photo that we located was this.

UNIDENTIFIED FEMALE: Is it him?

UNIDENTIFIED MALE: A little bit older, but yes.

UNIDENTIFIED FEMALE: My sweetheart is alive. Oh my God.

(END VIDEO CLIP) BROWN: I'm Pamela Brown in Washington. You are in the CNN Newsroom on this Sunday evening. It is 5 a.m. in Kyiv and the people of Ukraine are awakening to the nightmare of a 55th day of war. Near Kyiv, crews searching the rubble of two high rise apartment buildings have recovered the bodies of at least 41 civilians so far. And the search is not over. And the Russian assault in fact is escalating in many areas as we speak.

We want to warn you that this next video is graphic and you may find it disturbing. This is the northeastern city of Kharkiv, where residential areas suffered a full day of extensive shelling.

Officials say at least five people were killed and more than a dozen injured, but that Ukrainian forces still managed to push the Russians back east of the city. And Mariupol, a port city under relentless siege since the war began, and official there saying Russian forces will stop people from entering or leaving beginning tomorrow. We're going to have more on that in just a moment.

But we're also learning more about a tense meeting with Austria's Chancellor where he confronted Vladimir Putin about the wars, growing carnage.

(BEGIN VIDEO CLIP)

KARL NEHAMMER, AUSTRIAN CHANCELLOR: I think he is now in his own war logic. You know, he thinks the war is necessary for security guarantees for the Russian Federation. He doesn't trust the international community. He blames the Ukrainians for genocide in the Donbas region. I think he believes he is winning the war.

(END VIDEO CLIP)

BROWN: Ukrainian President Volodymyr Zelenskyy says his country is in a daily state of heartbreak over the needless deaths of civilians, especially the younger victims. CNN's Jake Tapper sat down with him at the presidential office in Kyiv for an exclusive interview.

(BEGIN VIDEO CLIP)

JAKE TAPPER, CNN HOST: I'm sure you have seen the video of the Ukrainian mom finding her son in a well. What is it like for you as the president of this country to see those videos, to hear the cry of the moms?

ZELENSKYY (through translation): This is the most horrifying thing I have seen in my life. I look at this, first of all, as a father, it hurst so, so much. It's a tragedy. It is suffering. I won't be able to imagine the scale of suffering of these people, of this woman. It is a family's tragedy. It is a disaster. It is the dreams and the life you've just lost.

We live for our kids, that's true. Kids are the best we were given by God, my family. It is a great pain for me. I can't watch it as a father, only because all you want after this is for revenge and to kill. I have to watch it as the president of the state where a lot of people have died and lost their loved ones. There are millions of people who want to live. All of us want to fight but we all have to do our best for this war, not to be endless. The longer it is, the more we would lose.

(END VIDEO CLIP)

[22:05:00]

BROWN: Zelenskyy also told Jake that he would not surrender territory in the east in order to end the war.

In Mariupol, official there says Russian forces announced that they will close down the besieged city for entry and exit on Monday and warned that the men who remained would be "filtered out."

Now CNN cannot independently verify the claims but they come after Ukraine forces in Mariupol defy an ultimatum by Russia to surrender Sunday. CNN's Matt Rivers has more.

(BEGIN VIDEOTAPE)

MATT RIVERS, CNN CORRESPONDENT (voice-over): A Russian ultimatum to Mariupol defenders surrender by 1 p.m. Sunday. The Ukrainians did not listen. Our defenders continue to hold the defense said an advisor to Mariupol's mayor in response.

DENYS SHMYHAL, UKRAINIAN PRIME MINISTER: Now, city still has not fallen, there is still our military forces, our soldiers so they will fight until the end. And as for now they still are in Mariupol.

RIVERS: A main pocket of resistance centered here at the Azov Stall steel plant. It's unclear how many fighters remain in the city. still difficult for CNN to gather verified information. A lack of internet service makes reliably contacting people in the city extremely hard.

Still, what is coming out of the city shows that it is now almost completely occupied by Russian troops keen to show off, they're handing out rations to starving civilians. But the Ukrainian parliament human rights commissioner says such handouts are mere propaganda, amounting to no more than a loaf of bread and a bottle of water per day. It is the Russian military, remember, that has caused such suffering. It's weeks long bombardment of Mariupol cutting off its population from food, water and medical supplies.

President Zelenskyy says the situation in Mariupol remains as severe as possible just inhuman. This is what the Russian Federation did, deliberately did and deliberately continues to destroy cities. Russia is deliberately trying to destroy everyone who is there in Mariupol.

An estimated 100,000 people remain in and around Mariupol and need to be evacuated, but they remain trapped. On Sunday, not one humanitarian corridor was open, meaning getting large numbers of people out remained impossible. Russia's military goals are clear, dominate Mariupol and move on.

SAMUEL RAMANI, OXFORD UNIVERSITY: Mariupol has to fall before they can move those forces back up to the rest of eastern Ukraine.

RIVERS (on camera): And those Russian forces getting freed up to move, does what?

RAMANI: If you freed those horses, that means that they'll be able to more aggressively conquer Kharkiv, for example, which is where they're already launching shelling almost every single day, and also, they'll be able to move more of those forces towards Odessa.

RIVERS: But for now, Mariupol still has not fallen. Destruction from previous battles litter the city's landscape. And as Ukraine's remaining forces declined to surrender on Sunday, Russia with a chilling response, its defense ministry saying in part, "In case of further resistance, all of them will be eliminated." Matt Rivers, CNN, Lviv, Ukraine.

(END VIDEOTAPE)

BROWN: And I want to bring in Kim Dozier, CNN Global Affairs Analyst and Contributor at Time Magazine. So Kim, as Russia moves toward a massive ground offensive in the east, the conventional wisdom is that the wide open areas give Russia a huge tactical advantage and Ukraine successful guerrilla warfare won't be as effective. Do you agree with that?

KIMBERLY DOZIER, CNN GLOBAL AFFAIRS ANALYST: To a certain extent, yes. The 40,000 some odd Ukrainian forces that are entrenched in the area already as part of the war in the Donbass that started well before this past February, they are going to be in a sense sitting ducks for a lot of Russian artillery. But the Russians are having to close a very large gap from north to south if they want to encircle those 40,000 Ukrainian troops about a 300 mile gap from the cities in the north down to Mariupol or Kherson in the south.

And every Russian military expert I've spoken to, and military official, they all say they don't yet see the Russians having brought in enough troops to do that. It's going to take a lot of troops to hold that amount of territory. And the other thing is, then you got that 300 mile line of Russians, that's something that the Ukrainian troops can pick off from either side. But this is also why you see the U.S. trying to rush in heavy artillery, the kind of equipment that the Ukrainians will need to level the battlefield to level their capability with the Russians.

BROWN: Right in the first shipments of Washington's latest military aid have arrived, according to our latest reporting. Is this a race for Russia to launch the offensive before those weapons arrive?

[22:10:03]

DOZIER: It sort of is, but you know one of the things that's happening though with the -- some of the Russian troops that got pulled out of areas around Kyiv, and moved around, all around Ukraine, have started arriving in other positions north and south of this eastern area that they're trying to enclose. But those troops have already lost buddies, they're exhausted, they got to rest in tents in, you know, farmer's fields. It's not like they got to go back and get Garrison, hot showers, that kind of things. These are tired troops, and they're going up against Ukrainian troops that are highly motivated. So what you see is the potential for a grinding war where, you know, Moscow -- Putin doesn't seem to care that the troops are tired, he's just going to send them in wave after wave.

BROWN: So what I hear you saying is, this is just going to go on and on, right? I mean, you -- doesn't sound like you see an end in sight at this point, as long as the Ukrainians continue to put up this resistance?

DOZIER: I think that's why you hear the Secretary of State Tony Blinken and others saying that this war could last through this whole year and beyond. Because Putin doesn't seem to have left himself a way out, or to be admitting to himself that anything's going wrong. Therefore, he's going to keep, you know, a war of attrition, who's better than giving up.

BROWN: Well, then what do you think about what the Chancellor in Austria said after his meeting with Putin that Putin apparently according to his account, told him that it's better at this ends earlier rather than later, and that he thinks he's winning. What do you make of that?

DOZIER: Well, the cynical part of me that says, of course, you'd like it to end earlier because you're having trouble getting enough troops for the fight. And those sanctions are going to begin to bite on all of Russia's defense industries, the things the industries that produce tanks and ammunition, because this war is eating up a lot of that.

But when he says something like it would be better if this war ends sooner, you worry that maybe he'll use something else in his arsenal, like nuclear weapons, to wrap it up faster. And I don't think Putin understands the ramifications of that. I would hope that the world would respond in horror, even a lot of the countries China, Hungary, places that have tried to stay on the fence throughout this.

BROWN: All right. Kim Dozier, thank you so much for staying up late for us on this Easter Sunday. We appreciate it.

DOZIER: Thank you.

BROWN: Well, the U.S., NATO and many other countries have levied heavy sanctions against Vladimir Putin, his inner circle, and they long list of Russian oligarchs, but everyday Russian citizens who have nothing to do with the war are very much feeling it in their pocketbooks as well. ITV News' Carl Dinnen takes a look.

(BEGIN VIDEOTAPE)

CARL DINNEN, ITV NEWS REPORTER: It's not just the oligarchs, ordinary Russians are also finding their lives disrupted by sanctions. Vera (ph) rents a small apartment. She was about to buy her own place, but then interest rates hit 20%. And along with everything else, the price of dog food is going up.

UNIDENTIFIED FEMALE (through translation): More luxury products, not everyday necessities have risen in price by about 30%. Everything else, bread, milk, eggs, potatoes, fruits and vegetables have increased by about 10% to 15%.

DINNEN: Who do you hold responsible for the economic problems that Russia faces?

UNIDENTIFIED FEMALE (through translation): The people responsible for these economic problems are the people who impose the sanctions. Our government is responsible for the fact we didn't properly find substitutes for foreign products. We should pay more attention to this now.

DINNEN: Those who are closer to the center of par talk tough on sanctions. Pyotr Tolstoy, Deputy Chairman of the Duma is himself under sanction.

PYOTR TOLSTOY, DEPUTY CHAIRMAN OF STATE DUMA (through translation): I'm under E.U. sanctions. I'm under British sanctions, under U.S. sanctions and under Japanese sanctions. And, you know what, nothing has changed. I have a Japanese car, a Toyota. Probably I should sell it a retaliation. That's all nothing else has changed in my life, I assure you.

DINNEN: In downtown Moscow international designers have shut up shop temporarily they say and for what the signs on their doors euphemistically call technical reasons.

[22:15:04]

(On camera): More than 600 global companies have voluntarily withdrawn from the Russian market in whole or in part, and economists are expecting a 10% to 15% contraction in the Russian economy, potentially the sharpest recession since the days of the Soviet Union.

(Voice-over): So far, Russia's Central Bank has managed to prop up the ruble and alleviate some of the initial financial shock, but the Russian economy is heading for a difficult place. Whether that has an impact on Russia's actions in Ukraine is another question. Carl Dinnen, ITV News, Moscow.

(END VIDEOTAPE)

BROWN: And coming up this hour, Ukrainian refugees making it all the way to the southern border only to be told they have to leave their pets behind. We'll tell you why, and who's trying to help them.

Also tonight, we're going to show you how artificial intelligence is getting better than humans at detecting cancer. But first a teenager missing for three years is found shivering right outside the gas station 700 miles away. Tears of joy from his family when they realized their son is still alive. You're in the CNN Newsroom.

(BEGIN VIDEO CLIP) UNIDENTIFIED MALE: Holy crap.

UNIDENTIFIED FEMALE: Is it him?

UNIDENTIFIED MALE: A little bit older but yeah.

UNIDENTIFIED FEMALE: My sweetheart is alive. Oh my God.

(END VIDEO CLIP)

(COMMERCIAL BREAK)

[22:20:03]

BROWN: In Utah, a teenager with autism has been located after he was missing for three years. CNN's Camila Bernal has more on this amazing and emotional story. Camila.

CAMILA BERNAL, CNN NATIONAL CORRESPONDENT: Pam, this is a remarkable story and the Summit County Sheriff's Office calling it serving with compassion. It all started a couple of weeks ago when authorities started getting phone calls reporting 19-year-old Connerjack Oswalt, they say he wasn't breaking the law but they went out to try to help him a number of times.

This is in the greater Park City Utah area. And it was last Saturday when they received another phone call. They went out there and this time he allowed them to help him all of this encounter was caught on police body cam video. Here's what happened.

(BEGIN VIDEO CLIP)

UNIDENTIFIED MALE: You look like you're shivering. You cold? You want to come sit in his car and warm up for a minute? We can't have you sitting in front of the door here all night.

CONNERJACK OSWALT: (Inaudible).

UNIDENTIFIED MALE: Sorry, I can't hear you.

OSWALT: As long as I'm not going to take anywhere.

UNIDENTIFIED MALE: No, you're not being taken anywhere. Just come sit in the car and warm up. Where's your shopping cart at?

OSWALT: Got stolen.

UNIDENTIFIED MALE: You got stolen?

OSWALT: Yeah.

UNIDENTIFIED MALE: That's no good.

OSWALT: (Inaudible).

UNIDENTIFIED MALE: OK. UNIDENTIFIED MALE: Do you want to sit in my front passenger seat where it's warm.

OSWALT: Yeah.

UNIDENTIFIED MALE: Come in here and warm up.

UNIDENTIFIED MALE: OK, do you have a knife or a gun or anything like that?

OSWALT: (Inaudible).

UNIDENTIFIED MALE: OK. So see (bleep). What's -- where were you at when your shopping car got stolen?

OSWALT: I don't know.

UNIDENTIFIED MALE: What's that?

OSWALT: It doesn't matter.

(END VIDEO CLIP)

BERNAL: And after that encounter, it was a dispatcher who was able to go through pages and pages of missing children and found Connerjack Oswalt, who had been reported missing in September of 2019. And that was in Clear Lake, California. Then authorities were able to contact his mother. She told them that he had a very distinctive birthmark on his neck.

They were able to find that and then it was his stepfather who went to Utah to identify him in person. The stepfather then called Connerjack's mom, that phone call was also caught on police body cam video. It was a moving moment. Here it is.

UNIDENTIFIED MALE: The missing person photo that we located was this.

UNIDENTIFIED MALE: Yes.

UNIDENTIFIED MALE: And then the photo that came from Nevada for the arrest was this.

UNIDENTIFIED MALE: Holy crap.

UNIDENTIFIED FEMALE: Is it him?

UNIDENTIFIED MALE: A little bit older, but yeah.

UNIDENTIFIED FEMALE: And what stood out to me was the ears. You know, not knowing him.

UNIDENTIFIED MALE: Yeah.

UNIDENTIFIED MALE: He looks pretty similar to this. His hair's longer right now. His beard is a little bit thicker.

UNIDENTIFIED MALE: Yeah.

UNIDENTIFIED FEMALE: My sweetheart is alive. Oh my God. Thank you (inaudible).

UNIDENTIFIED MALE: Yeah, I definitely will do my best to bring it home.

(END VIDEO CLIP)

BERNAL: And the sheriff saying there was not a dry eye in that room, including law enforcement. We know that he is now receiving the care and resources that he needs. Pam.

BROWN: Beautiful ending to that story. Wow. Camila, thank you.

Well, multiple mass shootings across the country casting a cloud over this Easter holiday weekend and shedding further light on America's gun violence epidemic. CNN's Nadia Romero has those details.

NADIA ROMERO, CNN NATIONAL CORRESPONDENT: Pamela, unfortunately plenty of shootings happen across the country during this holiday weekend. Let's start in the city of Pittsburgh. Police say they were called out to a large house party. Some 200 people were there and the majority of them underage.

Police say there were drugs, guns and alcohol and a shooting happened inside and outside of a rented Airbnb property. And we know that two people died in that shooting. Police say there were two boys who were under the age of 18, eight gunshot victims as well and countless other people who were injured, from jumping out of the window of that property trying to get away from the shooting.

Police say they are looking for multiple shooters but they don't have any suspects in custody. Here's the police chief explaining why this is their top priority.

[22:25:01]

CHIEF SCOTT SCHUBERT, PITTSBURGH POLICE: But this is our priority and we're not going to sleep until we get who did this. This shouldn't have happened. And we're sick about it. And we're going to do everything we can to get those responsible for it. So I said we owe it to the victims. We owe it to their families, and we owe to our communities.

(END VIDEO CLIP)

ROMERO: And in the early morning hours of Easter Sunday, at least nine people were injured in a shooting in Hampton County, South Carolina. No deaths were reported. And the police there are still investigating. Pamela.

BROWN: All right, Nadia Romero. Thank you. Well, we have seen a lot of images of Ukrainian refugees fleeing with their pets, but some are having a hard time getting those pets into the U.S. Up next, we're going to explain why that is. And meet a woman who is helping those refugees and their four legged friends. We'll be back.

(COMMERCIAL BREAK)

BROWN: Updating you now on the situation in Mariupol, Ukraine tonight, about 100,000 civilians are believed to be trapped in the besieged city. Ukraine's President says some 5000 children were forcibly deported from Mariupol to Russia and there's no evidence as to where they are now.

The Regional Governor says as many as 22,000 people have been killed in the city since the beginning of the war.

[22:30:01]

Well, the arc of Ukraine's President Volodymyr Zelenskyy is a remarkable one, from actor and comedian to the leader of a country suddenly at war, and his exclusive interview with President Zelenskyy CNN's Jake Tapper asked him to talk about this historic moment in time, and what drives him.

(BEGIN VIDEO CLIP)

JAKE TAPPER, CNN HOST: You've inspired a lot of people, including not just here in Ukraine, but around the world. Who inspires you? Who are your heroes? Whose story do you look to for inspiration during dark days here?

VOLODYMYR ZELENSKYY, PRESIDENT OF UKRAINE (through translation): Only the people, I believe our people are genuine and unique. And I just can't afford to be worse than them, when at certain moments, I feel like all of this is dangerous. I understand that all the rest of us are going through this as well. That's what people are feeling like, if you're in basements, who lost their children.

What our soldiers feel like right now. And I understand I have to be the strongest one on this situation. And this is all, and most important is the way my children look at me. They have to be proud of me. This is the most important thing. I do everything for this.

(END VIDEO CLIP)

BROWN: Imagine you were forced to flee your home as the Russian army advanced. What would you take with you? For so many refugees in Ukraine, that answer is simple. It includes their beloved pet. They wouldn't leave their pets behind. Every pet lover I know can relate. But it hasn't been easy, especially for Ukrainians who have now made it to the U.S.-Mexico border only to find out they cannot cross with their pets. Ukraine is on a list of 50 countries with a high incidence of rabies. So federal health regulations require them to leave their dogs behind.

Victoria Pindrik joins me now. She is the founder of the Save Ukraine Relief Fund and is helping Ukrainians with pets at the border in Tijuana. Victoria, I cannot imagine leaving my puppy bingo behind if I had to. I mean how devastating that is for these Ukrainians who make it all the way to the border with their pets, and then have to leave the pet behind. So tell us about why this has hit you in the heart so much and why you started this effort?

VICTORIA PINDRIK, FOUNDER, SAVE UKRAINE RELIEF FUND, (SURF): So that was actually not the original reason why I even went to Tijuana. A friend of mine told me that he was going down to Tijuana to help Ukrainian refugees. I'm originally from Russia. I was born in Moscow, Russia, I speak Russian. And I wanted to help translate and just be available to the refugees.

So a few of us Kevin Silver (ph), Jeff Asros (ph) and I went down to Tijuana to just be available to the refugees. My whole plan was to help translate and help the kids that were down there. And if the few hours that we were there, I saw a few dogs being returned back to the camp and quickly realized that there was a sudden need, they were being turned away at the border.

BROWN: And so you jumped into action, right? Tell me what you've been able to put together since you saw that happening?

PINDRIK: So our first instinct was to find out why they're getting turned away. What is really going on at the border, there was just so many inconsistencies. There was a few pets that were able to get through. But most of them were being turned away on the bus back to the camp. So it was to find out what was going on the border. Get on the phone with the CDC and find out how Mexican organizations, Mexican veterinarians can help us, make sure that they're in compliance to make sure they can enter the border.

BROWN: So why -- did you have an understanding of why some pets were being allowed in with Ukrainian refugees and others weren't?

PINDRIK: There was a lot of inconsistencies. We've heard so many different things. But ultimately, we are working with the CDC to make sure that they are compliant to enter to America.

BROWN: Of course. Then how are you able to connect the pet that was left behind with its rightful Ukrainian owner?

PINDRIK: American lovers got involved. I was not involved in that.

BROWN: So the process as you well know, for getting pets into the U.S., it can take weeks I mean you need permits, vaccine certain papers, records, possible quarantine, explain how you and other volunteers have been able to help?

PINDRIK: The process for pets vary from countries as well as airlines. I am more familiar with America's process and the CDC guidelines which I became familiar with just in the recent days. So the process is they have a fine guidelines that they're not going to loosen with. So we're just trying to make sure that the Mexican organizations and veterinarians become compliant so that they can enter the United States.

[22:35:02] BROWN: And just on a more emotional level like why was this so important to you reconnecting, reuniting the animals with their Ukrainian refugees during this just horrific time in their lives?

PINDRIK: I got to know a lot of the refugees on a more personal level, their stories, their journeys, what they were going through just to end up in Tijuana, their last step before entering the United States and understanding that they had to face that last obstacle with being separated from their animal just completely broke me inside, but I knew I had to jump into action, get the resources that I needed to make sure that that they will be reunited.

BROWN: Because I know you own a cat, right?

PINDRIK: I do.

BROWN: Animals bring in so comfort to, yeah, I mean, I have a dog bingo. And animals bring so much comfort, right. And it must mean the world to them to be reunited with their pets. And I'm curious, you said, for those that had to be left behind, they would just be trucked back to the tent. I mean, what would have happened to them? Had you not stepped in to help with this effort?

PINDRIK: I don't know. I'm just -- I'm really glad that I was in the right place at the right time to make sure that I can make this happen.

BROWN: Oh, my gosh, I mean, so many people are. And you had mentioned at the beginning of the segment, that you were born in Moscow, you came to America as a refugee. How does the plight of all these people resonate with you as you speak to them and help them and speak to them and Russian? How has it affected you?

PINDRIK: Well, as you mentioned, I did come to America as a refugee. My parents took my brother and I and left Russia. We left the regime. But ultimately, I'm a humanitarian, if I can be there for people suffering these horrible atrocities and help them in any way I will. And I knew that my ability to speak Russian would be an acid and I found this way to help.

As a Russian I feel an obligation to be there for the -- you know, your Ukrainian brothers and sisters, because I feel that there are Russians out there that don't believe this propaganda. And I'm lucky enough to be in the United States right now. And I feel that when I went to the border, I found something that I do feel connected with, especially because I do have a rescue and even if I didn't being a humanitarian, if I feel that there's something that I can help with, I will.

BROWN: You have such a beautiful heart. Victoria, your story is inspiring. You've helped so many human beings and animals through your hard work and dedication. Thank you so much for coming on to share your story.

PINDRIK: Thank you. BROWN: Researchers are working on a new tool to detect breast cancer, artificial intelligence and early results show it's more accurate than human doctors.

(BEGIN VIDEO CLIP)

UNIDENTIFIED FEMALE: Red mark that's what the AI said.

UNIDENTIFIED MALE: That's right. That's correct.

UNIDENTIFIED FEMALE: That's a cancer.

UNIDENTIFIED MALE: That's -- that basically says this is a very high chance that this is cancer.

(END VIDEO CLIP)

BROWN: And for a quick programming note, don't miss the unbelievable true story of the man who took on Vladimir Putin and live to expose the truth. The Sundance Award Winning CNN film Navalny airs next Sunday night at 9:00 right here on CNN.

(COMMERCIAL BREAK)

[22:42:27]

BROWN: There have been articles written about how artificial intelligence could replace truck drivers or receptionist one day but are you ready for computers to take over for doctors? CNN's Elizabeth Cohen reports on how AI is being used to read mammograms and could spot early signs of breast cancer that human eyes can't see.

(BEGIN VIDEO CLIP)

ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: Jasmine Souers was just 25 years old when she made a startling discovery.

JASMINE SOUERS, BREAST CANCER PATIENT: I remember standing in the mirror one day with a rib tank top and I could clearly see that one breasts was larger than the other.

COHEN: She went to her doctor and not one, but two mammogram showed everything was fine. They said it wasn't cancer, but Souers pushed her doctors to keep looking and they did an MRI. Almost the whole breast with up.

COHEN: Cancer all over her left breast and the mammograms had missed it.

DR. OTIS BRAWLEY, JOHNS HOPKINS UNIVERSITY: If everybody got mammography according to current standards, we still have 35,000 to 40,000 women dying every year. Mammography is not perfect.

COHEN: Dr. Otis Brawley, an oncologist at Johns Hopkins University says one reason is that reading mammograms can be very subjective.

BRAWLEY: One radiologist versus another, you may have one sees something and one doesn't.

COHEN: But it's 2022 and computers can read mammograms now to maybe even better than humans by using artificial intelligence or AI.

BRAWLEY: I do believe artificial intelligence may transform the mammogram.

COHEN: At New York University, an AI program created by Professor Krzysztof Geras can detect cancers on mammograms that are imperceptible to humans.

(On camera): I mean, that red mark right there. That's the AI saying what?

KRZYSZTOF GERAS, RADIOLOGY PROFESSOR: That's the AI saying, look here, there is a very high chance that this part of the image contains cancer.

COHEN: And the radiologist didn't see it, but the AI saw it.

GERAS: That's right, yes.

COHEN: The technology could be especially important for younger women like Souers who have denser breasts.

BRAWLEY: When we do a mammogram on a younger woman's breast, the breast on mammography is white. And we're looking for something white the tumor in a white background.

COHEN: Think of it like finding a snowball in a blizzard.

(On camera): Why might a computer, artificial intelligence be better than radiologist?

[22:45:01]

GERAS: These kinds of complex patterns are somehow difficult to understand for humans and AI just doesn't have this problem. It's never gets tired. It's always going to be at its best.

COHEN: And at MIT, an AI program created by Professor Regina Barzilay and her student Adam Yalla goes a step further. It can say whether a woman is at high risk for developing cancer in the future based on her mammograms in the present. You're looking at Professor Barzilay, his own mammograms. She was diagnosed with breast cancer in 2014.

(On camera): So in 2012, when you were 42, you had a mammogram. And the radiologist said --

REGINA BARZILAY, ELECTRICAL ENGINEERING & COMPUTER SCIENCE PROFESSOR: That it's fine.

COHEN: So the artificial intelligence that your team invented, you tried it out on your 2012 mammogram years later, and what did it show?

BARZILAY: It showed that I was in their highest risk of breast cancer. Nobody would ask radiologists, can you look at this image of healthy woman and say whether she's going to get cancer in two or three years. So you bring in AI technology to the task that humans can't do.

COHEN: Do we know what the artificial intelligence is seeing?

ADAM YALLA, GRADUATE STUDENT, MIT: It can be many little things as image all at the same time, that come together to give you that this person's higher risk, they can understand things in a way that is different from what we would as people would glean from looking at the image.

COHEN: The research is still early. But if these technologies pan out, they could save lives by leading to earlier detection and treatment of breast cancer.

(On camera): With this artificial intelligence replace a real human radiologist?

BARZILAY: I absolutely do not see it as replacing the radiologist, I just sees it the machines and the human have very complementary strength. If you can put the two together, hopefully we can do this screaming much more effectively than we're doing now.

COHEN: Souers thinks about what would have happened if she trusted that first image of her breast.

SOUERS: I think the biggest question for me is what would have happened had I not done the additional screening? What if I had just landed on that first mammogram and they said negative and just go on with that? I think that to me is probably the scariest idea.

COHEN: If you had listened to the results of that mammogram. What would have happened?

SOUERS: I don't know. I don't know if I'd be here today.

COHEN: Her hope that better technology in years to come will mean that other women won't have to catch their own cancers. Elizabeth Cohen, CNN Jacksonville, Florida.

BROWN: This just into CNN brand new video from the besieged Ukrainian city of Mariupol. This is what is left at Mariupol following the latest round of Russian shelling. People walking past destroyed military vehicles now just hunks of metal. Can you imagine just walking right by that? Ukrainian fighters in the city are refusing to surrender as Russian forces close in. And official there says the Russians have announced the city will be closed off for entry and exit on Monday morning that men who stay there will be "filtered out."

Well this morning on CNN's State of the Union Grammy Award Winning Singer Dave Matthews talked with our Jake Tapper and debuted a new song to support refugees in Ukraine and all over the world.

(BEGIN VIDEO CLIP)

DAVE MATTHEWS, SINGER-SONGWRITER: My mom used to always say that war is sort of like madness, it's like a cancer, it's like cells gone arrived suddenly we everything that we really naturally care about other humans, and our family gets torn apart. And like is happening right now where you are in Ukraine is just unfathomable to those of us who are far from it, but it's not only happening there, it's happening in Yemen, it's happening in Myanmar, it's happening in Nigeria.

There's just so many places where, you know, Afghanistan where people are trying to just survive and it's violence that's not allowing them to and terrible violence and so those of us, you know, so many of us are part of this chorus of people that are trying to or hoping that we can somehow turn the tide.

And so I thought I would just join in and in as many ways as possible, raise people's awareness and so get some friends together and play a song that I just finished writing that I think somehow pertains to it but at least it pertains to all of us. It's called something to Tell My Baby. Thank you very much, Jake.
