Since Olivia Munn was diagnosed with breast cancer more than two years ago, the actress has been open about her battle with disease. Now, she’s sharing another intimate memory from the beginning of her fight: A moment she shared with John Mulaney before undergoing a double mastectomy in May 2023.
Olivia shared the sweet moment on Instagram.
In honor of World Breast Cancer Research Day, which fell on Monday, Olivia shared this video of John perched on the end of her hospital bed as they had a tender conversation before she was taken into the operating room for a double mastectomy. We can’t hear the words they’re saying to each other, but it looks like there was a lot of love between them in that moment.
“This was May 2023 right before I was wheeled in for my double mastectomy, the first of 5 surgeries I would have in a determined battled to beat breast cancer,” Olivia wrote, adding, “My breast cancer and my mother’s breast cancer are both very aggressive, fast-moving cancers. And because of funding for breast cancer research we both had a path to survival.”
She called for more funding for breast cancer research.
After explaining that she’s currently on endocrine therapy to manage her cancer, Olivia implored her followers to donate to breast cancer research so that treatments like hers can continue to be developed and improve.
“Funding is still desperately needed to help find cures, perfect the treatments and most importantly determine which patients need them,” she continued. “By donating to breast cancer research you’re directly contributing to saving countless women’s lives. There are many charities that are working hard to eradicate breast cancer.”
Olivia ended her post by encouraging her followers to be proactive about their health.
After sharing her support for fellow cancer fighters, Olivia encouraged her followers to take a breast cancer risk assessment test.
“Every woman over 30 should take this test and know their score,” she said. “Anything above 20% is considered high risk and you should implore your doctor to order a breast MRI for you.”
She has said she has “years” to go in her cancer journey.
When Olivia spoke at Time’s Woman of the Year gala in February 2025, she said that though she’s been “feeling pretty good,” she also knows her fight isn’t over.
“I have years to go in my cancer treatment, but on that Friday, my joints didn’t ache, and I wasn’t too hot or too cold from going into a surgical menopause, and my brain fog had cleared — at least for that day, anyway,” she said at the gala, via USA Today.
Here’s hoping things only continue to get better for Olivia, and that by sharing her story, she’s able to help more women get diagnosed early so they can be on the road to recovery, too.
