A tearful Shannen Doherty revealed on Tuesday that her cancer has returned, and is now stage 4.

“I’m petrified,” the Beverly Hills 90210 actress told Amy Robach on Good Morning America (as seen in the clip below).

Shannen, who also appeared in Charmed, first received a breast cancer diagnosis in 2015 and chronicled her battle with the disease on social media.

Remission followed in 2017, but Shannen got word from doctors that the cancer had returned about a year ago.

“I don’t think I’ve processed it. It’s a bitter pill to swallow,” she said to the Good Morning America host, herself a breast cancer survivor.

The 48-year-old said she initially kept the diagnosis a secret, telling only one colleague on the upcoming Beverly Hills 90210 reboot, Brian Austin Green.

Brian became her confidant on set as she also had to confront the sudden death of former co-star Luke Perry while she faced her own difficult prognosis.

Shannen, who has been married to Kurt Iswarienko since 2011, said she was going public with her condition because it was going to be revealed in court documents for a lawsuit she filed against State Farm over fire coverage.

Her home sustained damage in the 2018 Woolsey fire.

“I want to control the narrative,” she said.
