Overview
- Munn, in a Sunday CBS Sunday Morning interview, said her public posts led to a 4,000% rise in people taking the Lifetime Risk Assessment.
- She said her modeled risk now reads zero after a double mastectomy, an ovariectomy, and a partial hysterectomy.
- She first learned she had Stage 1 breast cancer in April 2023 when the online questionnaire estimated a 37.3% lifetime risk despite a clear mammogram and ultrasound.
- The Lifetime Risk Assessment is a short web-based survey that flags elevated lifetime risk, which can guide next steps when imaging alone misses an early tumor.
- She credited husband John Mulaney for steady support through appointments as they raise two young children, and she is back at work on Apple TV+'s Your Friends and Neighbors, which returns Friday, April 3, 2026.
