Tennis legend Chris Evert has been diagnosed with stage 1 ovarian cancer.

In a Twitter post linking an ESPN article Evert co-wrote with ESPN journalist Chris McKendry, Evert said she wanted to share her diagnosis and story “as a way to help others.”

“I feel very lucky that they caught it early and expect positive results from my chemo plan

“Thanks to all of you for respecting my need to focus on my health and treatment plan,” Evert wrote in a statement posted on Twitter.

67-year-old added that she will appear from home at times during ESPN’s coverage of the Australian Open, which begins January 17.

After Evert’s announcement, the Australian Open’s official Twitter account posted, “Thinking of you here and wishing you a speedy and full recovery.”

“We are all with you and behind you Chrissie, you are a true champion and I have no doubt you will conquer this nasty opponent,” another tennis great and longtime rival of Evert, Martina Navratilova, said.

Evert has won 18 Grand Slam singles titles and three Grand Slam doubles titles in her career.
