While filming the third season of the hit show, How I Met Your Mother, actress Cobie Smulders learned that she had ovarian cancer. However, she chose to keep the diagnosis to herself and underwent several surgeries over the next two years to remove the affected tissue, before finally opening up about her experience in an interview with Women's Health in 2015.
"I had tumors on both ovaries," the Avengers star told the magazine. "The cancer had spread into my lymph nodes and surrounding tissues." Despite beating the disease, Smulders added, "I don't think I'll ever feel like I'm cancer-free. Now that I'm five years out, I'm trying to think of it as a positive thing and what can I learn from it. And if I can create more awareness, I'll do it."
