Free Test Reveals Hollywood Actress’s Symptom-Free Breast Cancer: ‘I’m So Lucky’

A free online risk assessment flagged a high cancer risk for Olivia Munn despite no symptoms. The Hollywood actress told CBS Sunday Morning she had a clear mammogram and ultrasound.

How the risk was discovered

The assessment, available through the National Cancer Institute, calculated a 37.3 percent lifetime risk. The free test reveals risks that standard imaging had missed in this case.

Munn learned she had luminal B breast cancer in April 2023. She kept the diagnosis private for about a year before speaking publicly in March 2024.

Treatment and surgeries

She underwent five surgeries, including a double mastectomy and a hysterectomy. Those procedures aimed to reduce her future risk score to zero.

Munn is now on hormone therapy. She has described the medication side effects as tough and exhausting.

Support and personal life

Her husband, comedian and actor John Mulaney, attended every medical appointment. She credited him for steady support and levity during treatment.

At 45, Munn is cherishing small moments with her two children. She is balancing recovery with a professional return to the series Your Friends and Neighbors.

Public message and awareness

In interviews, Munn urged other women to check their own risks. She wanted to highlight that symptom-free breast cancer can be missed by routine scans.

She summed up her feelings with the words “I’m so lucky.” Her decision to go public aimed to encourage testing and early assessment.
