She is the winner of 59 Grand Slam tennis titles, and now that she’s retired from the game, you can often find her skiing in Aspen. But, unfortunately, we have some sad news to report about tennis legend Martina Navratilova, as she has been diagnosed with breast cancer. The good news is that the disease was detected early, and her prognosis is excellent. Navratilova has a non-invasive form of breast cancer, and it is said to be the “best-case scenario” when detecting the disease. She has already had a lumpectomy and will begin six weeks of radiation treatment in May. Our best wishes go out to Martina for a quick and speedy recovery!
