Shannen Doherty revealed that her breast cancer diagnosis has returned and reached stage 4 in an interview with Good Morning America Tuesday.

Doherty, 48, was first diagnosed with breast cancer in 2015 and underwent treatment for about two years before announcing in 2017 that she was in remission.

The actress, who starred in Charmed and Beverly Hills 90210, has been open about her battle with cancer since she first detailed her diagnosis.

“I don’t think I’ve processed it,” Doherty said. “It’s a bitter pill to swallow in a lot of ways… I definitely have days where I say why me? And then I go, well, why not me? Who else? Who else besides me deserves this? None of us do.”

She said that after both the initial diagnosis and the more recent one, “my first reaction is always concern about, ‘How am I going to tell my mom? My husband?'”

“My mom is a ridiculously strong, courageous human being. So is my husband, but I worry about him,” Doherty said.

“I’m petrified. I’m pretty scared,” she added.

“There are definitely days where I say, ‘Why me?’ And then I go, ‘Why not me? Who else?'” Doherty said. “Who else besides me deserves this? None of us do.”

She kept filming, working 16-hour days, to prove she “can work, and other people with stage 4 can work, too.”

“You know, our life doesn’t end the minute we get that diagnosis. We still have some living to do,” Doherty said. But still, “I had moments of great anxiety where I thought I can’t really do this.”
