Tennis great Chris Evert has revealed she is cancer-free, just over a year after she began her fight against the illness.

Evert began chemotherapy in January 2022 after she was diagnosed with ovarian cancer.

Doctors caught Evert's cancer early after she had a preventative hysterectomy following the death of her sister, Jeanne, from the same disease.

The 68-year-old, who concluded her course of chemotherapy last May, confirmed the positive news on Tuesday, writing for ESPN: "A year ago, I started a journey to protect myself and my loved ones from the risks associated with the BRCA-related ovarian cancer that took my sister Jeanne's life. 

"It is only because of the genetic road map my sister left behind and the power of scientific progress that we caught my cancer early enough to do something about it.

"My doctor said if left undiscovered, in four months' time I would probably have been Stage Three like Jeanne, with very few options. Instead, I was diagnosed with Stage Three ovarian cancer, and I immediately began six rounds of chemotherapy.

"Today, I'm cancer-free, and there's a 90 per cent chance that the ovarian cancer will never come back."

However, Evert added her "story isn't over" and confirmed that on December 1, a year to the day since her hysterectomy, she underwent a double mastectomy in order to reduce the risk of developing breast cancer.

Evert said she is "well on the road to recovery".

She explained: "I have one more surgery left to complete reconstruction. They say this part is easy, but I can assure you, the last five years have not been.

"As relieved as I will be to get to the other side of this, I will always have a heavy heart. I will never heal from losing Jeanne, and I will never take for granted the gift she gave me in the process.

"My sister's journey saved my life, and I hope by sharing mine, I just might save somebody else's."

Evert won 18 grand slam titles across her illustrious career and enjoyed an on-court rivalry with Martina Navratilova.

When Navratilova confirmed her own cancer diagnosis earlier this year, Evert was among those to offer their support.

Evert posted on Twitter: "Thinking of @Martina today and supporting her journey, like she did mine, with love and prayers. This is a woman who takes on challenges with strength and resilience…You got this, Martina."
