American actress and model Olivia Munn, 43, revealed Wednesday that she underwent a double mastectomy last year after being diagnosed with an “aggressive and fast-progressing” form of breast cancer. On her Instagram account, after appearing at the Oscars in Hollywood on Sunday with her partner – American comedian John Mulaney – Olivia Munn wrote: “I hope that by sharing this, it will help others find comfort, inspiration and support for their own journey” with this disease.

The actress, known for her roles in the franchises Iron Man, Lego, negative” for cancer risks and a “normal mammogram”. Despite this result, her gynecologist preferred two months later to have her undergo a statistical assessment on her risks of contracting breast cancer taking into account her family history, or the age at which she had her child. The result showing a probability of 37%, Olivia Munn then underwent an MRI, an ultrasound and a biopsy which “revealed luminal B cancer in both breasts”, an “aggressive and rapidly progressing” form of cancer.

“Thirty days after this biopsy, I had a double mastectomy, going from a state where I felt perfectly fine to waking up in a hospital bed after ten hours of surgery,” says the actress in posting photos of herself in the hospital, also explaining that she had undergone four operations in total. In May 2013, American superstar Angelina Jolie made global headlines by also revealing that she had undergone a double mastectomy.
