Olivia Munn has updated her fans on her breast cancer diagnosis.

The X-Men actress took to Instagram to post a video of her timeline. She was previously diagnosed with bilateral breast cancer in April 2023.

“I’ve gotten lots of DMs and questions about my breast cancer timeline so I thought that I should clearly lay it out for you guys,” she said. “I hope that by doing so it helps others who have gone through it or are going through it right now.”

“Maybe feel a little comforted and knowing that I’ve gone down the same path and I’m doing okay,” she added.

In the clip, she laid out key dates. After having mammograms in Jan. 2022 and Jan. 2023, she took a genetic test in Feb. 2023 that revealed she had a zero chance of having genetic cancer. However, two months later, she received her diagnosis.

She also had an MRI, ultrasound, and biopsies in March and April 2023, followed by a "nipple delay, lymph node dissection, and double mastectomy” that May.

She decided to have an egg retrieval the following month, then had a breast reconstruction in Sept. 2023, a lupron treatment in Nov., a partial hysterectomy/oophorectomy in April 2024, and an Arimidex treatment in Aug. 2024.

Munn and her husband, John Mulaney share one son, 2-year-old Malcolm. According to People, she froze her eggs when she was 33 and 39 years old, and decided to do it once more after her diagnosis.
