Martina Navratilova, one of the greatest athletes in history, has been diagnosed with Stage 1 throat cancer.
In addition, an unrelated form of breast cancer, still in its early stages, was discovered during throat examinations. Navratilova was previously diagnosed with non-invasive breast cancer—ductal carcinoma in situ, or DCIS—in 2010.
“This double whammy is serious but still fixable, and I’m hoping for a favorable outcome,” Navratilova said. “It’s going to stink for a while, but I’ll fight with all have I got.”
The 66-year-old will begin treatment this month, with a strong prognosis considering a history of positive outcomes for these cancers. The throat cancer is type HPV, which responds well to treatment. Six months after her breast cancer diagnosis in 2010, Navratilova was deemed cancer-free following a lumpectomy and six weeks of radiation.
“I really didn’t talk much about breast cancer before I had it,” Navratilova told PEOPLE. “Now, I’m approached by women and we share our stories. It’s encouraging to see that there’s life after cancer.”
