Munn was diagnosed with bilateral breast cancer in April 2023 after tests revealed she had luminal B — a fast-moving, aggressive cancer — in both breasts. She has since had five surgeries including a lymph node dissection, a double mastectomy and a hysterectomy.

Olivia Munn starred in a new SKIMS campaign with her mastectomy scars on display. The actress shared her luminal B breast cancer diagnosis earlier this year. She discovered her cancer thanks to a breast cancer risk assessment and encourages other women to calculate their score.
