In the ESPN article, McKendry recalled learning of Evert's cancer diagnosis: "It was short, simple and yet so damn complicated."

"I read the text five times before it sunk in," McKendry said. "At first, [Evert] needed more information. She needed privacy to process it. And she needed to physically recover from two surgeries," she continued. "Then, she needed to tell her story. In good times and bad, Chrissie has always owned her story. So, here we are." According to McKendry, Evert has stage 1C ovarian cancer that is in "an early stage." The cancer, she added, was found following a preventive hysterectomy. "Cancer has not been detected elsewhere in her body," she noted. Evert also told McKendry that her annual exams, "including tests for the amount of cancer antigen 125 protein in her blood, her ultrasounds and MRI with contrast were all negative," per the ESPN story.

But, I have comfort in knowing the chemotherapy is to ensure that cancer does not come back," said Evert. "As someone who has always had control over my life, I have no idea how I'll respond to chemotherapy. I have to give in to something higher." Evert, whose sister Jeanne Evert Dubin died from ovarian cancer in February 2020 at age 62, added: "Be your own advocate. Know your family's history. Have total awareness of your body, follow your gut and be aware of changes. Don't try to be a crusader and think this will pass."
