Just four months after being diagnosed with Stage 1 breast and throat cancers, tennis legend Martina Navratilova announced she is now cancer-free.

“As far as they know I’m cancer-free,” Navratilova said in an interview with TalkTV. “I still need to do the right breast probably with radiation but only for a couple of weeks and that’s more preventative than anything else.”

The radiation treatment should last about two weeks, Navratilova noted.

The 66-year-old was diagnosed with cancer in November and told the world on Jan. 3 about her treatment plans. She also previously was diagnosed with breast cancer in 2010 and underwent a lumpectomy.

Navratilova did not mention anything about her potential return to Tennis Channel, where she helps with various tournament coverage. She missed January’s Australian Open broadcasts. The next Grand Slam is the French Open, which begins on Sunday, May 28. 

The former world No. 1 is best known for holding the open-era record for the most combined Grand Slam titles. She has won 18 singles Grand Slam titles, 31 women’s doubles titles and 10 mixed doubles titles, for a record total of 59 major titles.
