Revealing a Life-Altering Fibromyalgia Diagnosis
Before her battle with cancer, Olivia Munn faced another significant health challenge: fibromyalgia. Diagnosed in early 2019, Munn described her experience as bewildering, recounting years of unexplained ailments, fatigue, and pain. In an interview with People, she shared, “I wasn’t really sure what was going on with me. I was going through a lot of different ailments for years and not knowing what was happening.” Fibromyalgia, an incurable disorder, brings with it chronic muscle pain, sleep disturbances, and memory issues, significantly impacting the lives of those who suffer from it.
To combat the effects of the disorder, Munn had to overhaul her lifestyle entirely. She adopted a gluten-free, dairy-free, and sugar-free diet, despite how challenging it was to let go of familiar comfort foods. “I had no choice,” she admitted. “It was either continue down a path leading to multiple autoimmune diseases or make the necessary changes to feel better.” Stress management also became a priority, as stress can exacerbate fibromyalgia symptoms. Through determination and a commitment to her wellness, Munn found a way to navigate the challenges of the disorder.
A Courageous Battle Against Breast Cancer
In March 2024, Olivia Munn revealed another life-altering diagnosis: breast cancer. The disease, described as aggressive and fast-moving, required immediate and extensive medical intervention. Munn underwent a double mastectomy in May 2023, a procedure that marked the beginning of a long and arduous journey. In addition to the mastectomy, she later had a hysterectomy, further underscoring the severity of her diagnosis.
On August 18, 2025, in honor of World Breast Cancer Research Day, Munn took to Instagram to share a deeply personal video documenting a tender moment with her husband, comedian John Mulaney, just before her surgery. In the video, Mulaney is seen comforting her, his forehead resting against hers as she prepared to be wheeled into the operating room. The emotional post resonated with fans and followers, many of whom praised her bravery and transparency.
In her caption, Munn emphasized the critical role of breast cancer research in her and her mother’s battle with the disease. She wrote, “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.” Munn, now on an endocrine therapy treatment plan, highlighted how advancements in medical research have been pivotal in developing lifesaving treatments, urging her followers to support research efforts.
