Olivia Munn Shares Breast Cancer Diagnosis

Olivia Munn has revealed she was diagnosed with breast cancer last year, in the hope of helping others going through it too.

The Newsroom star shared a moving post on Instagram explaining that despite being tested for cancer genes in February 2023 and having a normal mammogram, 2 months later she received her diagnosis, leading to four operations.

“Luminal B is an aggressive, fast moving cancer. Thirty days after that biopsy, I had a double mastectomy. I went from feeling completely fine one day to waking up in a hospital bed after a 10-hour surgery the next.”

Olivia added, “I’m lucky. We caught it with enough time that I had options.

In her post, she thanked her family, friends, doctors, nurses and hospital staff, as well as her husband, comedian John Mulaney.

“I’m so thankful to John for the nights he spent researching what every operation and medication meant and what side effects and recovery I could expect. For being there before I went into each surgery and being there when I woke up, always placing framed photos of our little boy Malcolm so it would be the first thing I saw when I opened my eyes.”

“Thank you to the friends who’ve had breast cancer and the friends who connected me to friends who’ve had breast cancer for guiding me through some of my most uncertain and overwhelming moments. ”

Olivia, who walked the red carpet with John at the recent Oscars, captioned her post, “I hope by sharing this it will help others find comfort, inspiration and support on their own journey.”

According to Breast Cancer Network Australia, some signs/symptoms to look out for include:

  • a lump in your breast or underarm (armpit)
  • thickening, swelling or changes in the size or shape of your breast
  • irritation or dimpling of your breast skin
  • pain in any area of your breast
  • indentation (puckering) of part of the breast when you lift your arms
  • redness, crusting or flaky skin in your nipple area or your breast
  • inverted nipple or pain in your nipple area
  • nipple discharge other than breast milk .
