The Charmed alum—who shared her stage 4 breast cancer diagnosis in 2020—recently opened up about the emotional process she endured while having to undergo surgery earlier this year.

"January 16, 2023," she wrote alongside a June 13 Instagram video of herself in the hospital. "Surgery. I had a tumor in my head they wanted to remove and also biopsy. I am clearly trying to be brave, but I am petrified. The fear was overwhelming to me."

That fear also extended to those closest to Doherty.

"Scared of all possible bad outcomes, worried about leaving my mom and how that would impact her," she noted. "Worried that I would come out of surgery not me anymore. This is what cancer can look like."

Doherty was diagnosed with breast cancer began in 2015 and went into remission two years later. However, in February 2020, the 52-year-old shared that her cancer returned the year before and was categorized as stage 4.

"Our life doesn't end the minute we get that diagnosis. We still have some living to do."
