Olivia Munn'smother has been diagnosed withbreast cancer. The "Newsroom" star, 45, shared the news in anInstagram post on Wednesday, July 9, more than a year afterrevealing her own breast cancer diagnosis. Munn said that after being diagnosed with breast cancer herself in 2023, she urged her mother to take a breast cancer lifetime risk assessment test.

"From my mom being there after my double mastectomy to me being there after hers," Munn wrote in her post. "From me having to find an oncologist, to my mom and I sharing one. I can tell you this: going through cancer is really hard. But there's something about watching a loved one go through it that is even more heartbreaking."
