Olivia Munn opened up about her breast cancer journey, sharing an honest look into her experience with the hope of helping anyone going through the same thing. "Welcome to the worst club with the best members. I heard that after I was diagnosed with breast cancer and it turned out to be true. The sisterhood I’ve found of women who have battled/are currently battling the same fight are the most incredible, generous, supportive people I’ve ever met," wrote the actress, 46, incredibly grateful for the supportive community she has found 🤍🩷 📽️ : #oliviamunn #breastcancer #healthjourney #cancerjourney
