Olivia Munn shared an update on her "tough" breast cancer journey during a sit-down interview on Good Morning America on Monday, March 30th. The 45-year-old Your Friends & Neighbors star spoke candidly with hosts Robin Roberts, George Stephanopoulos, and Lara Spencer about her experience.
In March 2024, Munn revealed that she had been diagnosed with bilateral breast cancer the year before. Despite having had a "clear mammogram" and "no symptoms," tests revealed that she had luminal B, a fast-moving and aggressive form of cancer, in both breasts.

During the interview, Roberts thanked Munn for being so open about her journey and asked how she's been doing. "I'm doing great," Munn replied. "The impetus for wanting to talk about it was that I had something that I knew would help women - something that was free, like the lifetime risk assessment test."
Munn, who underwent five surgeries including a lymph node dissection, a double mastectomy, and a hysterectomy, said she has some side effects from her medication, including nodules that developed on her neck. She admitted that she's been struggling to compare herself to other people who have had the same cancer and medications as her because they haven't been struggling the way she has.
"I say all that to kind of bond with anybody out there who's going through that or finding comfort in their own journey, because it's not something that I've easily found," Munn shared. "But I'm doing great, and my mom is doing great. She was diagnosed about a year after I was."
Munn has since been urging women to take the breast cancer risk assessment, which estimates a woman's risk of developing invasive breast cancer within the next 10 years and within her lifetime based on various factors such as family history, the date of a woman's first period, breast density, and age when her first child was born. A lifetime risk score of 20 percent or more suggests high risk and may require additional diagnostic screening.
