Olivia Munn said Wednesday that her mother was diagnosed with and underwent treatment for breast cancer, revealing the news more than a year after she announced her own diagnosis.

Munn wrote on Instagram that after her own breast cancer diagnosis, she encouraged her mother, Kim Munn, to take a lifetime breast cancer risk assessment. It's the test that Munn's own doctor encouraged her to take, which led to a score that prompted an MRI test and, ultimately, a biopsy.

Munn, the "Newsroom" actor was found to have luminal B cancer in both breasts in 2023, she said last year.

wrote that her mother had a score of 26.2%, and although mammograms came out fine, she insisted her mother get an MRI.

"Shortly after that MRI, my mother was diagnosed with Stage 1 Her2 breast cancer," Munn wrote. "She has since completed 12 rounds of chemo and will continue monthly Herceptin transfusions until this fall."
