Olivia Munn’s Risk Assessment Leads to Mother’s Early Breast Cancer Diagnosis

A high-risk 26.2% score on the assessment led to an MRI-confirmed Stage 1 HER2-positive diagnosis; her mother completed chemotherapy, underwent a double mastectomy, with monthly Herceptin scheduled through fall.

Overview

  • Kim Munn scored 26.2% on the Tyrer-Cuzick lifetime risk assessment despite clear mammogram results, leading Olivia to insist on an MRI that diagnosed Stage 1 HER2-positive cancer.
  • Kim has completed 12 rounds of chemotherapy, undergone a double mastectomy and is scheduled to receive monthly Herceptin infusions through fall.
  • Olivia and Kim share the same oncologist, and Olivia has been at her mother’s side during treatments, describing caregiving as even more heartbreaking than battling her own cancer.
  • The test first led to Olivia’s Luminal B breast cancer diagnosis in 2023 and now guided her mother’s early detection, showcasing the tool’s life-saving potential.
  • Olivia urges gynecologists to integrate lifetime risk assessments with mammograms to spot high-risk cases, particularly in women with dense breast tissue or family histories.
