Martina Navratilova Says She's 'Cancer Free' In Moving Piers Morgan Interview

The former Czech-American pro saw a video of her ringing a bell at the clinic to signify the end of her cancer treatment, during which she broke down in tears. She explained, "I'm crying just watching it again because you can't wait to ring."

Navratilova underwent radiation therapy every day for three weeks, mixed with three weekly bouts of chemotherapy, which she said was "certainly the hardest thing I've ever done".

"That was the hardest part because the first week was both chemo and radiation. When you start to feel bad, you don't know if it's from the chemo or the proton. I didn't didn't really feel the proton until the third week, but then your mouth hurts and your throat starts to close up. Everything is swollen and very uncomfortable, and the proton makes your saliva feel weird.

"You don't really taste things the right way. Chemo does the same thing to your throat but then it dries it up. So you just get hit all over the place and I don't think doctors do a pretty good job of telling you how the shit is going to hit the fan."
