— -- “Avengers: Age of Ultron" star Cobie Smulders revealed on “Good Morning America” that the reason she chose to go topless on the cover of Women’s Health magazine was to help spread awareness about ovarian cancer, a disease she was diagnosed with at the age of 25.

The mother of two said it took two years and multiple surgeries to remove the cancer.

"I don't think I'll ever feel like I'm cancer-free," she told the magazine. "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.”

She is now keeping busy reprising her role as Maria Hill in the new “Avengers” film, which opens nationwide on Friday.
