Olivia Munn revealed Wednesday that she was diagnosed with breast cancer nearly a year ago, and that she has since undergone a double mastectomy.

“In February of 2023, in an effort to be proactive about my health, I took a genetic test that checks you for 90 different cancer genes,” Munn wrote in a lengthy statement posted on her social media.

“I tested negative for all, including BRCA (the most well-known breast cancer gene). My sister Sara had just tested negative as well. We called each other and high-fived over the phone. That same winter I also had a normal mammogram. Two months later I was diagnosed with breast cancer.”

Munn added, “In the past ten months I have had four surgeries, so many days spent in bed I can’t even count and have learned more about cancer, cancer treatment and hormones than I ever could have imagined. Surprisingly, I’ve only cried twice. I guess I haven’t felt like there was time to cry. My focus narrowed and I tabled any emotions that I felt would interfere with my ability to stay clearheaded.”

The actress credited her OBGYN for encouraging her to calculate her Breast Cancer Risk Assessment Score. “I wouldn’t have found my cancer for another year — at my next scheduled mammogram” if not for the OBGYN’s advice. After calculating her risk score — 37 percent in her lifetime — Munn got an MRI, then an ultrasound, and then a biopsy that showed she had Luminal B cancer — “an aggressive, fast moving cancer” — in both breasts.

Thirty days after the biopsy, she had a double mastectomy, Munn wrote. “I went from feeling completely fine one day, to waking up in a hospital bed after a 10-hour surgery the next.” However, Munn said that she was “lucky” to catch the cancer in time to still have treatment options.

As for why she kept her battle secret, Munn added, “I’ve kept the diagnosis and the worry and the recovery and the pain medicine and the paper gowns private. I needed to catch my breath and get through some of the hardest parts before sharing.”

Munn also thanked her friends, family, and team of doctors for helping her throughout her battle, as well as John Mulaney, with whom she shares a son named Malcolm; Munn was thankfully well enough to accompany Mulaney to the Oscars this past weekend. “Thank you for fighting so hard to be here for us,” Mulaney wrote in the comments of Munn’s post. “Malc and I adore you.”
