Lemigova and Navratilova tied the knot in 2014. They're the first same-sex couple eve to appear as full-time cast members on the Real Housewives franchise since it launched in 2006.

On Monday, PEOPLE confirmed nine-time Wimbledon singles champion Navratilova, 66, has been diagnosed with two, separate cancers. A spokesperson for the retired athlete shared that Navratilova sought medical attention for a swollen lymph node in her neck — which was found to be cancerous.

At the time, a mass was also found in her breast, which also turned out to be cancerous.

The spokesperson told PEOPLE, "The cancer type is HPV and this particular type responds really well to treatment," and added that the cancers are both in "early stages."
