Charmed alumni Brian Krause and Drew Fuller are showing admiration and support for their co-star. 

The actors exclusively gave an update on Shannen Doherty's health and well-being. Shannen, who was first diagnosed with breast cancer in 2015 before later going into remission, confirmed in February 2020 that her cancer had returned. In Brian and Drew's eyes, she is a perfect example of strength.

"She's amazing. She's a f--king warrior," Drew exclusively told E! News at That's 4 Entertainment 90s Con 2023, which was held March 17 through March 19. "She is so cool and calm and powerful. I'm in awe of her strength, and I'm constantly inspired by her."

At the time, Brian shared a similar message, noting she teaches him "that you got to keep throwing punches."

"I think she's underestimating how strong she is and strong-willed and determined," he added. "She's an inspiration, for sure."

Since her cancer diagnosis, Shannen has continued to work in the entertainment industry. She has also used her voice to spread awareness about the reality of her cancer battle.

"I feel like I have a responsibility in my more public life, which I separate from my acting life, to talk about cancer and perhaps educate people more and let people know that people with stage 4 are very much alive and very active," she said in 2021 during a panel for her film List of a Lifetime, per People. "My husband [Kurt Iswarienko] says that you would never know that I have cancer. I never really complain. I don't really talk about it. It's part of life at this point."

At the time, Shannen noted that she doesn't have a bucket list, but rather one larger plan on her agenda.

"I'm very much like there's no bucket list because I'm going to be the longest-living person with cancer," she said, per the outlet. "If I had to say one, it would just be living. That's the only thing on my list at this point." 

Shannen joined her fellow Charmed stars Drew, Brian, Dorian Gregory, Rose McGowan and Holly Marie Combs on stage at 90s Con 2023, which made for a nostalgic cast reunion. To see other stars who attended the multi-day event, keep reading..
