Martina Navratilova Announces Breast Cancer Diagnosis on Good Morning America

Hall of Fame tennis player Martina Navratilova went on ABC's Good Morning America today and announced she was diagnosed with breast cancer.  The 53-year-old tennis great told Good Morning America anchor Robin Roberts, herself a breast cancer survivor, that she was "devastated" upon hearing the news.

Navratilova was originally diagnosed in February and underwent a procedure to clear her of the initial cancer.

Navratilova said there is a "very small chance of it coming back." 

"It is just in that one breast," Navratilova said. "I'm okay and I'll make a full recovery."

Navratilova said she will be treated with six weeks of radiation therapy in May. She told Roberts she feels good physically, but has troublesome days handling the emotions of it all.

"I'm this healthy person, I've been healthy all my life, and all of a sudden I have cancer, are you kidding me?" she said.

Navratilova said she is using her diagnosis as a means to spread the message about the importance of mammograms.

"The reason I wanted to speak about this is to encourage these woman to have mammograms," she said. "I just want to encourage women to have that yearly check-up."

"I was feeling absolutely 100 percent fine (at the time of her diagnosis)," she said.
