Actress Shannen Doherty revealed Tuesday her cancer is back.

During an ABC News appearance, the 48-year-old "Charmed" actress said the breast cancer is at stage 4.

"It's going to come out in a matter of days or a week that I have stage 4," Doherty said during the interview. "So my cancer came back and that's why I'm here."

She was initially diagnosed in 2015 and announced in 2017 she was in remission.

Doherty said she's quietly been battling cancer once again for more than a year and is having a hard time processing that the cancer is back.

"I don't think that I've processed it," she 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 beside me deserves this?' None of us do. I would say that my first reaction is always concern about how am I going to tell my mom, my husband."

The reason she decided to make the announcement is due to a court filing that will be released within the coming weeks over a legal battle with an insurance company, she said.

"I'd rather people hear it from me."
