Olivia Munn has for more than a year been speaking out about the importance of a breast cancer risk assessment test that helped lead to her diagnosis in 2023, and she has now shared that that very same test also led to her mother’s breast cancer diagnosis.

Olivia Munn has revealed her mother has been diagnosed with breast cancer, more than a year after the actress shared her own cancer diagnosis.

Breast cancer survivor Olivia Munn says her mother Kim is battling the same disease. "My mother was diagnosed with breast cancer," the Newsroom and Your Friends and Neighbors actress, 45, wrote on Instagram Wednesday.
