When actress Olivia Munn isn’t on set filming Apple TV’s Emmy nominated series Your Friends & Neighbors, appearing on a late-night talk show, or spending time with her family, she’s probably talking to a group of women about her breast cancer journey. Most often, women approach her first, asking specific questions about her diagnosis while reflecting about their own, hoping for a path forward after hearing the words, “You have cancer.” For Munn, retelling her story is never easy, but after her diagnosis, she decided to dedicate the rest of her life to advocating for women, especially those facing breast cancer. “I’ll tell my story as many times as I need to because that’s what spreads awareness and lets other women know they’re not alone,” Munn says. Read the full conversation with Olivia Munn on her journey with breast cancer, her advocacy work, and how leaning into gratitude and the reality of her own fierce resilience has helped her to heal by tapping the link: webmd.com/breast-cancer/feat…
