In a new interview with People, former “Desperate Housewives” star Marcia Cross talks about being diagnosed with anal cancer a year and a half ago and the “gnarly” treatment she underwent for three months.

“I want to help put a dent in the stigma around anal cancer,” Cross says. “I’ve read a lot of cancer-survivor stories, and many people, women especially, were too embarrassed to say what kind of cancer they had. There is a lot of shame about it. I want that to stop.”

After discovering the cancer, Cross went through six weeks of radiation and chemotherapy.

“Surgery wasn’t recommended, which was a relief. You want to preserve sphincter muscles if possible,” she says. “Having woken up to its importance, I am now a big fan of the anus!”

Cross has now been in remission for almost a year, and her doctor says there is little chance of the cancer recurring.

“Every time I go to the bathroom, I think, That’s awesome! Thank you, body,” Cross says.

She also has a message for fans: “If something doesn’t feel right, listen to your body and talk to your doctor. Don’t let it go. It’s a very curable cancer if caught early, which mine was.”
