Actress Olivia Munn revealed on social media that she was diagnosed with an aggressive form of breast cancer last year and underwent a double mastectomy as part of her treatment. The 43-year-old star, known for her roles in movies and TV shows like "The Newsroom," shared in a heartfelt post that she had tried to be proactive about her health by taking a genetic test that checked for 90 cancer genes in February 2023. Despite testing negative for all of them, including the well-known BRCA gene, Munn was later diagnosed with luminal B breast cancer.

Over the past ten months, Munn has undergone four surgeries and spent countless days in bed, learning more about cancer, treatment, and hormones than she ever imagined. She expressed gratitude for her doctors, friends, and family, including her partner John Mulaney, who supported her through research on her operations and medications. Munn's risk assessment score, which took into account factors like familial breast cancer history and age, helped identify her cancer early, leading to a biopsy that confirmed the diagnosis.

Despite her struggles, Munn has maintained a positive attitude and shared many happy moments on social media, including glamorous photos from events like the Oscars, where she appeared with Mulaney. She emphasized the importance of being open about her journey with breast cancer in hopes of providing comfort, inspiration, and support to others facing similar challenges. Through her brave and candid post, Munn highlighted the importance of proactive health measures and the invaluable support of loved ones during difficult times.
