Olivia Munn, who has been open about her breast cancer journey, says her mom was diagnosed, too

Olivia Munn has for more than a year been speaking out about the importance of a breast cancer risk assessment test that helped lead to her diagnosis in 2023, and she has now shared that the same test also led to her mother’s breast cancer diagnosis.
Munn said in an Instagram post that her mother, Kim, was diagnosed with Stage 1 Her2 breast cancer, writing that while the assessment test saved her own life, she never thought it “would save my mom’s life as well.”
Munn is referring to The Tyrer-Cuzick Risk Assessment test, an free, online tool that uses a statistical model to estimate a woman’s risk of developing breast cancer over the next five years as well as over her lifetime, or up to about age 90, according to the National Cancer Institute. Munn shared a link on her Instagram page to the test.
“After my own breast cancer diagnosis in 2023, I urged my mother and sister to take the Breast Cancer Lifetime Risk Assessment test,” Munn wrote. “My mother scored 26.2%. Her yearly mammogram had just come out clear but because of that high score I insisted she get an MRI.”
Munn said her mother has since completed 12 rounds of chemotherapy treatment, with additional transfusion treatment continuing until the fall.
The “Your Friends & Neighbors” actress first revealed that she was diagnosed with a form of breast cancer known as Luminal B cancer in 2024. The cancer was found in both of her breasts, and Munn’s treatment included a double mastectomy and a hysterectomy.
The carousel of photos and videos that Munn posted included images of herself, along with her husband comedian John Mulaney, by her mother’s side while she appeared to be getting treatment. A video showed Munn’s mom ringing the bell after completing her chemotherapy treatments.
Munn added that her mom hopes that sharing her story “will help save someone’s life” and went on to thank the healthcare providers who cared for both of them.
“To anyone out there who is taking care of someone or has made it their profession to do so, thank you,” she wrote. “These fights can feel near impossible without you.”
While fighting cancer, Olivia Munn felt guilty she couldn’t always be there for her kids
The past two years have been a roller coaster for Olivia Munn: from the lows of treating an aggressive form of breast cancer to the highs of getting married to comedian John Mulaney and welcoming their second child with help from a gestational surrogate.
One low point? Feeling guilty that cancer treatment meant she couldn’t always be the mom she wanted to be.
Munn, 44, spoke with Savannah Guthrie from the NBC studio in Los Angeles. She’s currently struggling to find the right combination of medications while also trying to have enough energy to be a mom.
“I’ve got my hands full with a newborn and a toddler, and a lot of my energy is going towards them and it’s distracting a lot of the other side effects of my medication,” she told Savannah with a smile. Even so, she said, “I’m doing pretty good.”


“You’ve had five surgeries, you’re still struggling with finding the right kind of medication so that you can stay healthy, and at the same time, you’ve got a toddler — Malcolm’s about to turn 3 — and you’ve got this new baby,” Savannah said. “Tell me about that part of the journey, and kind of juggling these two conflicting moments in your life.”
Munn sighed deeply and said, “There is a lot of guilt that I had, and still have, from being sick for so long and being bedridden, so many surgeries. I thought that when I got through the big chunk of surgeries — the four surgeries in the beginning — that I would be able to get back on my feet. But then there came the first wave of medication and that just knocked me down and was debilitating.”
She continued, “I was just tired and not around that much, and I couldn’t hold him as much, and I couldn’t go to the playground as much, and I was really exhausted. There’s just a lot of guilt.”
Munn said that she has worked closely with her oncologist to figure out her physical capabilities.


“We’re just such a little family,” she said. “We’re really tight and we have a lot of fun and we laugh all the time. And John is just the most amazing husband and father. So we figure out a way to make it all work despite how tired I can be at times.”
Savannah, who is a mom of two herself, said, “Mom to mom, I’ll just tell you, you’re doing great. You’re there. That’s the most important thing — your mere presence.”
Olivia Munn Gets Real
At 45, the actress, advocate and mother is entering what she calls “a new chapter”—not just in age, but in intention.

nown for her quick wit, radiant beauty and fierce intelligence, Olivia Munn has long been a force in Hollywood, seamlessly moving between comedic timing and dramatic depth. But in recent years, it’s her vulnerability, honesty and courage off-camera that have truly reshaped how we see her—and perhaps how we see ourselves.
At 45, the actress, advocate and mother is entering what she calls “a new chapter”—not just in age, but in intention. Diagnosed with breast cancer at 42, Munn has emerged from a deeply personal battle with a renewed take. “Aging is great,” she says, with the kind of conviction that makes you believe it, too. “It means that you’re here. And I’m just getting started.”

You posted that you are “vintage” in celebration of your 45th birthday over the summer. Did it feel like one of the big ones?
“I like getting older! I’m interested to see what the next decades bring. In my 20s, I thought I was a fully formed human being. It was very much: ‘These are my opinions. This is how I will live life. I’m right. These are immovable truths.’ Then, I got to my 30s and I was taking in more information and setting goals. I was so set on what I was going to do, but it was also a period of time where I realized some of the choices I made in my 20s weren’t the smartest. When I got to my 40s, I was so ready to take what I learned and run with it. And then I was diagnosed at 42. All of a sudden, my plan to climb, celebrate and have fun came to a halt.”
Everything stopped.
“The light fully stopped in that moment. But because I had done so much work preparing for this decade of my life, I was able to be stopped in my tracks without falling backwards. Yes, it all stopped, but it didn’t shake my confidence. It didn’t shake my fortitude. It didn’t shake my belief in myself. It has never felt like the excitement in my life had to stop.
It more felt like that this is the part of my life where I have to go a little slower—where I have to stop and think about every decision. In the past, my brain was going a million miles a minute: ‘Do I get out of this relationship? Do I get into this relationship? Am I going to take this job? Am I going to take that job?’ All of a sudden, none of that mattered. There was one thing I had to do. When you get cancer, it is your full-time job. There’s only one goal. So, that is a really long, circuitous way of answering what it is like to turn 45. I’m still thinking of the right answer.”
That’s a great answer. It all seems far away until it isn’t.
“Right. When you’re 10, 30 seems old. It’s a lifetime away. I can still remember what it was like to be 5 years old very vividly. I remember all of it. That’s the gift of getting older: You have so much more life that’s now part of you, and that helps with your decision-making. I remember the mistakes I made, and I remember the good choices. The more time you’re on Earth, the more lessons in life you’ve had, and when you get older, you have a found ability to enjoy it so much more. There are two things none of us can avoid: great joy and great sadness. For me, coming to terms with that early on in my life is really OK. I learned that when the bad things come, that’s just part of it. When the good things come, that’s great and enjoy them. You have to be ready to embrace both because that is what existing entails.”
The ups and the downs really are a universal experience. Your life has changed a lot since you were on our cover four years ago—you now have two kids and a husband.
“For a long time, all the choices I made in my life were for me. If I was in a bad relationship, I was the only one who had to suffer those consequences. It was only my time being wasted. It was only my emotions being affected. All the personal choices I made were only affecting me. Now, all of my choices affect two little people who depend on me. My son and daughter need me to be a grown-up and they rely on me to make good decisions.
Let’s just say, for me, having children was the most significant opportunity I was ever given for self-growth. All of a sudden there are things that I felt as a kid that I just ignored, ignored, ignored, but they were playing out in my adult life without me realizing it.
I grew up in an abusive household with an abusive stepfather…I just recently opened up about it on Dax Shepard’s podcast. I was surprised I let it out. Actually, I didn’t realize the things that were coming out of my mouth, but I’m happy they did. The things that happened in my childhood gave me strength, grit, resilience and an unsinkability to handle anything scary in the world.
The thing I didn’t realize until I had children was that there’s something on the other side of that, which is the lack of self-worth—the feeling that I’m not good enough; the feeling that everything I have can be taken away in an instant. There are definitely cracks in my soul that formed when I was a child. I didn’t realize that when people would say certain things about me or certain things would happen, that it could seep through these cracks and embed somewhere in me…
Once I had kids, I was like, ‘Wait! This didn’t happen by choice!’ Everything came to the forefront. One day I was looking at my son, and I’m like, ‘Wow, the things that were screamed at me when I was a kid…’”

You can’t imagine yourself saying those things to anyone…
“Never! When I look at my children, I see myself—it’s like watching the 4-year-old me, and I literally want to say: ‘You end up with a family, and everything is great, but there are going to be all these things to deal with along the way. Just don’t be hard on yourself. Let it go.’ I would never want my children to hold on to any regrets or anything that makes them question their self-worth.
So, yes, I’ve been having to address all of these feelings I didn’t even know were there, and that’s come with age. It’s been so healing for me. I think the biggest thing I’ve learned is that you can’t focus on things that are going to happen no matter what. I can’t get mad that the sun goes down at night. Just like there’s zero benefit in worrying about getting older because it’s going to happen. The alternative is not something anybody wants. I am very aware that it can be annoying when people talk spiritually, and I am trying to be careful of that, but there’s some of that, too.”
It’s not annoying—it’s part of it.
“Something happened recently, and I said, ‘Well, because this happened, everything is better now. Everything is better now.’ My husband [Munn is married to comedian-actor John Mulaney] was like, ‘I think it was better before that happened.’ And I kept insisting, ‘No, it wasn’t.’ I kept going through the playbook of how it wasn’t, and now it’s better. And he kept saying: ‘I know that you see it that way, but it was really OK before all this transpired.’
It hit me in the same moment: ‘But it changed in my head.’ It was the first time in my life—in my entire life—that I’d actually thought about how the reality in my head is the reality of my life. If I’m being hard on myself, or if I’m absorbing what I think someone else is thinking about me or saying about me, or if I’m feeling like I’m coming up short, that is my reality.
Once I learned that—it was literally just two weeks ago—it was huge! The thing that has helped me is thinking about my children. I have to parent my 7-year-old self, and I go back and parent myself in a way that…I don’t want to say that my mom didn’t do a great job, but it was a different time. My mother was 27 years old, raising three biological children and two stepchildren. That was a very difficult time; I think it would be for anyone, but she was amazing. I think that, for her, it was really difficult to give each child the attention they needed in every single moment. We all know that as parents, we can’t be there for every little thing.
I do go back now because of everything I’ve seen with my children. I try to parent the younger me that’s still inside of me, so I can heal myself. It’s like in the movie Back to the Future. He’s doing all this stuff that’s changed in the future, but he doesn’t know it. As soon as he gets back to the future, his parents are happy and healthy. They’re financially stable and everybody’s doing good. Now he gets to walk in this life because everything’s been healed. I feel like that’s what I’m doing in real time. I’m learning that because of my children.”
It seems like you have a great support system. You have John, your kids, your mom. How is she doing after her own diagnosis?
“My mom has that quality in life that I really wish I had. She has a personality trait that is amazing. No matter what is happening to her, she has the ability to put it out of her brain and just keep going. She just keeps going forward.
There is a very core memory for me that happened when she was diagnosed. I wanted her to get her whole checkup; I didn’t want anything to be left behind, and she didn’t want to do it. I think parents of a certain age…they don’t want to hear bad news from a doctor, and so you have to force them to. I was really pushing her; I wanted her to get tested for everything.
She had the mammogram, and it was clear, but her risk assessment score was high. So I pushed for an MRI, which she didn’t want to do, and the doctors didn’t really want her to do it either. Everything seemed good. Her heart was good and every box was getting checked off with ‘healthy, healthy, healthy.’ But I kept pushing.
What I tell people all the time is: ‘Cancer wants us to ignore it.’ It wants us to be afraid to get the test results. Cancer wants us to be too busy to go get checked out. It wants to do whatever it wants to do in your body and travel wherever it wants to go. It just hopes that you are too busy or too afraid to find it. What you want to do is stop cancer before it breaks into your home. You want to find it when it’s still showing in the ring camera—not when it’s standing over your bed, inside your home.
And, then, my mom was diagnosed, and I’m telling you, it was a battle to beat her cancer—three months of weekly chemo and a year of monthly Herceptin infusions. You have to understand, my mom is Asian, and she’s very much been a tiger mom my whole life. She is the one that drove us to karate practice, drove us to piano, drove through the streets of Tokyo. She always was and she still is such a badass. As she’s gotten older, she’s very goofy and funny. She and John are truly best friends, and we have a very funny dynamic now, but she still has a very stoic quality.
Throughout this whole process, she was like, ‘Tell me what to do, and I will do whatever you say.’ I kept telling her I was prepared for this moment—there was no one more prepared than me to help my mother. I was ready to jump in.
I was home with her in Oklahoma after the double mastectomy. I was lying down in my bed, and she came in to talk to me. She was talking about something, then she turned around to leave…but before she walked out the door, she stopped at the foot of the bed, patted my leg and just said, ‘Thank you.’ Then she turned around and walked out. It was a very big moment for me because she doesn’t really do stuff like that. She’s very jokey when she says things, but this was serious. Here we both are—we’re both in there, both battling cancer and knowing that I was the one to find it for her and to push so hard, and now here we are. It was just this incredible moment.”

You’re all very lucky to have each other.
“One thing that people often ask me is if I ever feel like my body betrayed me. There is not a millisecond of thinking that. My body is what’s going to get me through this. How can I get mad at my body? No. It’s like in my relationship with John. Of course, we have arguments just like everyone else. But the biggest thing that’s helped us tackle any possible arguments in our relationship is that we never look at it like me against him or him against me. It is always us against the problem. We treat the cancer the same way. It is my body against the cancer. We’re in this together. We’re going to fight it.”
How Olivia Munn’s breast cancer diagnosis led to life-saving test that helped “Inside Edition” correspondent Alison Hall
“Inside Edition” correspondent Alison Hall is opening up about her breast cancer journey and how actress Olivia Munn‘s own cancer diagnosis influenced Hall’s decision to seek testing. Hall shared her story on “CBS Mornings,” explaining how Munn’s advocacy for early detection, along with a breast cancer risk assessment tool, led to her life-saving diagnosis.
Munn credited the risk assessment test, which uses various factors to evaluate lifetime breast cancer risk, for her early diagnosis. After hearing Munn’s story, Hall decided to take the same test. To her surprise, a doctor revealed that Hall’s lifetime risk for breast cancer was 36%.
“Wow, OK, that feels high,” Hall said, after hearing the news.
Hall, whose mother had breast cancer at age 50, had already undergone genetic testing for the BRCA gene in her 20s, which came back negative. She also had never had a mammogram until this year, after taking the risk assessment test.
Following the assessment, Hall was placed on a regular screening schedule, including mammograms and MRIs every six months. After an MRI revealed some abnormalities, Hall underwent biopsies, which confirmed she had breast cancer.
“This is actually good news,” her doctor told her. “It’s stage zero, the earliest it could possibly be caught.”
Hall was preparing to report on Munn’s battle with breast cancer when she received her diagnosis. Hall described it as “surreal” to become part of the news.
“I was prepared to do the test in order to promote awareness for breast cancer, especially with it being a subject so close to my heart,” she said. “I didn’t expect it to happen so soon, especially.”
Hall has chosen to undergo a double mastectomy next week to remove the current cancer and lower her risk of future diagnoses.
“I want to do whatever I can to prevent that for my future self and my future family,” Hall said.
Munn sent “CBS Mornings” a statement to deliver to Hall, saying, “You are now on the path to survival … By telling your story, you are creating a ripple effect of hope and saving lives.”
Hall expressed deep gratitude for Munn’s words and emphasized how sharing her story could help others.
“By Olivia sharing her story, she had a direct impact on my life,” Hall said.
As Hall prepares for her upcoming surgery, she is grateful for the support of her family and friends, including her husband, whom she calls her “human support person.”
Olivia Munn Has Heart-Eyes for John Mulaney and Baby Daughter Méi in Adorable New Pics: ‘Such a Smoosh’
The couple — who tied the knot in July 2024 — also share a 3-year-old son, Malcolm
After John Mulaney shared some sweet new photos with his baby girl, Olivia Munn couldn’t help but gush over the father-daughter duo!
On Saturday, Jan. 25, Mulaney, 42, posted three adorable — and hilarious — selfies with the couple’s 4-month-old daughter, Méi June, on Instagram. In the first picture, he pursed his lips, appearing to lovingly imitate the expression of his little one, who was swaddled in a towel for the shot.
In the second photo, the comedian made another silly face alongside his daughter, and in the third, he opted for an open-mouth expression while Méi stared directly into the camera.

And while Mulaney shared the fun father-daughter selfies with no caption, letting the shots speak for themselves, his wife added a note while reposting the pictures on her own Instagram.
Alongside the post, which she shared on Instagram Stories, Munn, 44, wrote, “[She’s] such a smoosh,” and added a heart-eyes emoji to show her sentiment for the duo.
Like the X-Men: Apocalypse actress — who also shares 3-year-old son Malcolm Hiệp with her husband — Mulaney’s fans and followers were obsessed with the adorable shots. “John in his dad era is my favorite 😂😍,” one top comment read, while others called Méi “beautiful” and “ridiculously cute.”
It is typically Munn, not Mulaney, who keeps fans of the couple updated about their kids. Earlier in the week, the actress shared a cute video of Méi playing in an activity center in an Instagram Stories post.
Alongside the clip, in which Munn repeatedly said hello to Méi and told her she loves her, the mom of two wrote that the little one is “so strong and happy”
“She’s wearing 6-9 months at 4 months old, so she can reach the bottom of the activity center,” she continued, “and her neck strength is 💯.”

Munn and Mulaney were first spotted together in June 2021, about five months before they welcomed Malcolm, and later tied the knot in an intimate New York wedding in July 2024. Only their son and a witness were in attendance.
The couple welcomed Méi months after the ceremony in September 2024 and announced the happy news in an Instagram post, which also revealed the meaning behind their daughter’s name.
“I am so proud of my little plum, my little dragon for making the journey to be with us. My heart has exploded,” Munn wrote in part. “Méi (pronounced may) means plum in Chinese 梅💜.”
At the time, a source close to the couple told PEOPLE that they were “in total bliss” with their two children, adding that “after everything they have been through there’s no tighter, closer little family.”
