Martina Navratilova said Wednesday that she has been diagnosed with a noninvasive form of breast cancer and her prognosis is excellent.
The 59-time Grand Slam champion (18 singles, 31 doubles, 10 mixed doubles) had a lump found during a routine mammogram in January. A biopsy later determined it was a treatable form of cancer called ductal carcinoma in situ.
People Magazine first reported the news. A doctor friend of Navratilova's was quoted in the article as saying that the detection of this cancer was a "best-case scenario." Navratilova will undergo six weeks of radiation therapy beginning next month.
"I cried," Navratilova said of finding out about the positive biopsy. "It knocked me on my ass, really. I feel so in control of my life and my body, and then this comes, and it's completely out of my hands."
Navratilova won a record nine Wimbledon titles, won a record 167 career singles titles, finished 1983 with an 86-1 record and won a record 74 straight matches in 1984. Bud Collins has called her "arguably, the greatest tennis player of all time."
