>> Robin: NOW AN ABC NEWS EXCLUSIVE.
WE KNOW YOU SAT DOWN WITH OLIVIA MUNN.
>> Michael: IT IS HER FIRST ON CAMERA INTERVIEW SINCE REVEALING
HER MOST RECENT SURGERY IN HER BREAST CANCER BATTLE.
WE DISCUSSED EVERYTHING FROM TREATMENT TO FERTILITY TO HER
HOPES FOR THE FUTURE. SHE WANTS TO SHARE HER STORY TO
HELP OTHERS. >> YOU NEVER KNOW WHAT'S GOING
ON IN SOMEONE'S LIFE. PRIVATELY PEOPLE ARE BATTLING
THINGS THAT YOU WOULD NEVER KNOW.
>> Michael: ACTRESS OLIVIA MUNN OPENING UP ABOUT THE PRIVATE
HEALTH BATTLE SHE'S BEEN FIGHTING AFTER AN UNEXPECTED
BREAST CANCER DIAGNOSIS LAST YEAR.
>> CLEAR MAMMOGRAM, CLEAR ULTRASOUND, GENETIC TESTING, I
HAD ZERO CHANCE OF HAVING ANY CANCER GENETICALLY.
THEN MY DOCTOR SAID THERE'S THIS LIFE TIME RISK ASSESSMENT TEST.
I TOOK IT FOR YOU. YOU WERE AT 37.3% WHICH PUTS ME
INTO HIGH RISK. SHE SAID I WANT YOU TO GET AN MRI.
THAT'S WHEN THEY SAID, WELL, WE FOUND SOMETHING.
>> Michael: WHEN YOU HEARD THE WORD CANCER, WHAT WENT THROUGH
YOUR MIND? >> I MEAN, HONESTLY, I JUST
THOUGHT OF MY BABY. CANCER, THAT'S THE WORD YOU
DON'T WANT TO HEAR. THERE'S A LOT OF OTHER THINGS
THAT YOU FEEL LIKE YOU CAN BEAT BY, YOU KNOW, CANCER TAKE DOWNS
A LOT OF PEOPLE. I JUST THOUGHT ABOUT MY BABY.
>> Michael: LAST APRIL SHE WAS DIAGNOSED WITH STAGE 1LUMINAL
BREAST CANSER IN BOTH BREASTS. WHAT DID THEY EXPLAIN ABOUT YOUR
PROGNOSIS? >> THEY SAID IF I WAS EXTREMELY
AGGRESSIVE THAT I COULD FIGHT THIS AND WIN.
BUT AT THE SAME TIME, ONCE THEY STARTED FINDING ALL OF THESE
LITTLE SPOTS IN MY BREAST, THERE'S ANOTHER TUMOR, ANOTHER.
THERE WAS AN URGENCY TO IT BECAUSE WE HAD TO GET IN AND
MAKE SOME REALLY BIG DECISIONS. >> Michael: MUNN GETTING A
DOUBLE MASTECTOMY JUST 30 DAYS AFTER RECEIVING THE DIAGNOSIS.
IN MARCH, THE 43-YEAR-OLD DECIDED TO OPEN UP ABOUT HER
EXPERIENCE ON SOCIAL MEDIA. >> DO IT FOR YOUR BABY.
>> Michael: INCLUDING THIS RAW MOMENT RIGHT BEFORE SHE WENT
INTO SURGERY. >> I'M READY.
>> Michael: HOW DID YOU KNOW YOU WERE READY?
>> I DIDN'T. I JUST HAD TO SAY IT.
SOMETIMES YOU JUST SAY IT AND HOPE THAT YOUR BODY WILL GO WITH IT.
>> Michael: WHY DID YOU WANT TO DOCUMENT THIS JOURNEY THAT
YOU'RE ON RIGHT NOW? >> WELL, BECAUSE IF I DIDN'T
MAKE IT, I WANTED MY SON, WHEN HE GOT OLDER, TO KNOW THAT I
FOUGHT TO BE HERE. THAT I TRIED MY BEST.
>> Michael: YOU'RE GONNA MAKE ME CRY.
>> YOU WANT THE PEOPLE IN YOUR LIFE.
YOU WANT THE PEOPLE THAT MAYBE DON'T UNDERSTAND WHAT'S GOING ON
RIGHT NOW TO KNOW THAT YOU DID EVERYTHING YOU COULD TO BE HERE.
>> Michael: MUNN SHARED A 2 1/2-YEAR-OLD SON MALCOLM WITH
HER PARTNER JOHN. HOW HAS IT BEEN HAVING JOHN
THERE TO SUPPORT YOU? >> HE'S HONESTLY JUST THE BEST
HUMAN BEING. HE COMES TO EVERYTHING IN LIFE
WITH SO MUCH COMPASSION AND UNDERSTANDING.
THE ONE PROBLEM WITH THAT, HE MAKES ME LAUGH SO MUCH THAT I'M
LIKE, THERE'S TIMES YOU HAVE TO LEAVE THE ROOM.
THIS IS INSANE. >> Michael: THAT'S WHEN YOU'RE
WITH A FUNNY MAN. >> I KNOW.
I JUST SAY LEAVE THE ROOM. YOU HAVE TO LEAVE.
YOU'RE GOING TO MAKE ME ANGRY NOW.
I'M GOING TO LITERALLY POP A FIST.
>> Michael: BECAUSE OF THE POTENTIAL IMPACT ON HER FUTURE
FERTILITY, SHE DECIDED TO UNDER GO EGG RETRIEVAL.
>> JOHN AND I TALKED ABOUT IT. WE REALIZED WE WEREN'T DONE
GROWING OUR FAMILY. RIGHT AFTER THE DOUBLE
MASTECTOMY I WENT THROUGH A ROUND OF EGG RETRIEVAL.
THAT'S SCARY. I HAVE A CANCER THAT BEEFS UP
WITH HORMONES SO I KNEW THERE WAS A RISK.
OUR DOCTOR SAID, LOOK. WE'RE GOING TO GET ONE FOR YOU
AND THEN WE'RE GOING TO CALL IT. THEN DOCTOR CALLED AND HE SAID,
HEY, WE GOT THE RESULTS BACK. IT'S TWO HEALTHY EMBRYOS.
WE JUST STARTED BAWLING CRYING, BOTH OF US.
>> Michael: HAVE YOU THOUGHT THAT FAR AHEAD ABOUT WHAT THE
FUTURE OF YOUR FAMILY LOOKS LIKE?
>> REALLY JUST HOPE IT WORKS OUT FOR US TO HAVE ANOTHER BABY.
WE JUST WANT ONE MORE. I'M NOT GOING TO ASK FOR TOO
MUCH MORE IN THIS LIFE, I PROMISE.
I JUST WANT ONE MORE BABY. >> Michael: BECAUSE LUMINAL B IS
A HORMONE TYPE BREAST CANCER, MUNN'S TREATMENT INVOLVES
SUPRESSING PRODUCTION OF THE HORMONES THAT CAUSE IT TO GROW
PUTTING HER BODY INTO MEDICALLY INDUCED MENOPAUSE.
>> THE HORMONE SUPPRESSION THERAPY IS BRUTAL.
IT GAVE ME NEXT LEVEL DEBILITATING EXHAUSTION.
I WAS IN BED ALL DAY LONG, ALL DAY LONG.
MY QUALITY OF LIFE WAS SO MINIMAL.
I WASN'T ABLE TO BE THERE FOR MY BABY.
>> Michael: DID HE NOTICE A CHANGE?
>> YEAH, YEAH. I MEAN, WHENEVER MALCOLM WOULD
COME HOME, HE WOULD RUN TO MY BED BECAUSE THAT'S WHERE HE
KNOWS I AM. THAT'S WHAT HE ASSOCIATED WITH ME.
THAT WAS JUST TOO DIFFICULT FOR ME TO TAKE.
I HAD TO FIND OUT IF THERE WAS ANOTHER OPTION SO I OPTED TO DO
THE HYSTERECTOMY WITH THE OVARECTOMY.
ALMOST IMMEDIATELY AFTER THAT MY ENERGY JUST CAME BACK FULL FORCE.
>> Michael: SOON MUNN SAID HER DOCTOR WANTS HER TO START
ANOTHER DRUG THAT WILL STOP HER FROM PRODUCING THE HORMONES
ELSEWHERE IN THE BODY. >> I HAVE BEEN AGGRESSIVE.
I DID EVERYTHING THEY TOLD ME TO DO.
I DID ALL THE BIG SURGERIES. AND NOW I'M SAYING, DO I HAVE TO
DO THIS EXTRA DRUG? >> Michael: AFTER ALL THE STEPS
YOU'VE TAKEN, WHY DO YOU THINK THAT WAS THE ONE THING YOU
QUESTIONED? >> IT'S SO TIRING.
IT'S SO TIRING. THESE DRUG ARE SO TIRING.
I KNOW THAT I'M GOING TO STAY AGGRESSIVE.
I KNOW THAT I'M GOING TO DO IT. I'M JUST SURPRISED THAT I'M EVEN
ASKING FOR ANYTHING LESS THAN AGGRESSIVE BECAUSE AS YOU KNOW,
IT'S NONSTOP. >> Michael: IT FEELS NONSTOP.
>> BECAUSE IT IS NONSTOP. >> Michael: GOING THROUGH ALL OF
THIS, HAVE YOU LEARNED ANYTHING NEW ABOUT YOURSELF?
>> I HAVE LEARNED THAT I'M A LOT BRAVER THAN I THOUGHT I WAS.
I LEARNED THAT THE MOST IMPORTANT THING TO ME IN LIFE IS
MY FAMILY. EVERYTHING ELSE CAN GO AWAY.
I DON'T HAVE MY CAREER, I DON'T HAVE MY BODY THE WAY THAT IT
LOOKED BEFORE. BUT AS LONG AS THE PEOPLE THAT I
LOVE AND CARE ABOUT ARE HERE AND HEALTHY AND THRIVING, NOTHING
ELSE MATTERS. >> MAMA.
>> MAMA. >> Michael: OLIVIA IS AMAZING.
SHE IS A FIGHTER. SHE SAID SHE HOPES OTHER WOMEN
WILL FEEL EMPOWERED ABOUT ASKING TO HAVE IS A RISK ASSESSMENT
DONE. HER DOCTOR SAID SHE USES IT ON
ALL OF HER PATIENTS BECAUSE GENETIC SCREENING DOESN'T FULLY
CAPTURE A WOMAN'S RISK OF GETTING BREAST CANCER.
IT TAKES INTO ACCOUNT WEIGHT, FAMILY HISTORY AND THE AGE YOU
HAD YOUR FIRST CHILD. YOU ALWAYS WANT TO MAKE SURE YOU
GO OVER RESULTS WITH YOUR HEALTH CARE PROVIDER.
>> Robin: THAT MESSAGE FROM HER IS GOING TO HELP COUNTLESS PEOPLE.
YOU KNOW FIRST HAND IT'S NOT EASY TO SHARE AND BE AS OPEN AS
SHE HAS BEEN. BUT SHE'S GOTTEN SUPPORT.
SHE TALKED TO YOU ABOUT THAT? >> >> Michael: SHE'S GOTTEN SO
MUCH SUPPORT. IT GOES TO SHOW HOW IMPORTANT
SUPPORT IS. SHE WAS FIGHTING THIS BATTLE
ALONE -- NOT ALONE, BUT PRIVATELY WITH HER FAMILY.
SHE SAID THE SUPPORT FROM THE PUBLIC PUTS A SMILE ON HER FACE.
SHE GAVE ME SOMETHING THAT WAS SO INSPIRATIONAL.
SHE TOLD ME THE WHOLE EXPERIENCE, IT HAS MADE HER BE
KINDER TO HERSELF. SHE SAID ALL THE THINGS I
REGRETTED, ALL THE OTHER THINGS. I LET IT GO.
I'M JUST KINDER TO MYSELF. SHE'S TAKING EVERYTHING DAYS, MINUTES,
SECONDS AT A TIME. >> Robin: THANK YOU FOR SHARING
YOUR CONVERSATION WITH HER. >> Michael: THANK OLIVIA FOR
SHARING IT WITH ME AND EVERYONE ELSE. >>George: AND EVERYONE CAN SEE IT ON
NIGHTLINE TONIGHT AS WELL?
>>Michael: YES.
