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.

Munn urged others to take the free, online risk assessment that she credits with saving her and her mother's lives.

Olivia Munn revealed that her mother was diagnosed with breast cancer after encouraging her to take the same Tyrer­-Cuzick breast cancer risk assessment that “saved my life.”
