She makes us laugh with her cheeky antics of HBO’s monster hit Curb Your Enthusiasm, but now Wanda Sykes is making headlines for a far more serious matter. The  47-year-old just revealed that she was diagnosed with breast cancer and underwent a double mastectomy, in an interview with Ellen DeGeneres, set to air Monday.

Cindy Geoghegan from the Y-Me.Org National Breast Cancer Organization has praised the actress/comedienne for going public with her battle, hailing it as an “act of heroism.”

“We are so grateful that Wanda has gone public with the news of her cancer. Breast cancer is a very personal thing and most people don't come forward, so it was really an act of heroism,” Cindy said in an exclusive interview with RadarOnline.com. “It raises awareness and sends a message to the public, ‘If it can happen to me, it can happen to anyone.’”
