Shannen Doherty broke down in tears as she gave fans a health update during a 90210 panel with her former castmates.
The actor, who has stage 4 breast cancer, was joined by the likes of Tori Spelling, Jason Priestley, Jennie Garth, Ian Ziering, Brian Austin Green and Gabrielle Carteris to discuss the hit '90s show.
The Florida panel was hosted PEOPLE Senior Editor Breanne L. Heldman and the cast got to reflect on the cult phenomenon that was their show.

However, at one point during the discussion, Doherty received a standing ovation from the fans.
The crowd jumped to their feet with rapturous applause and it left the actor in tears, with the 52-year-old saying: "Thank you so much.
"You guys know how much I love crying constantly. And I do, it seems. So, thank you."

Doherty is in the middle of a cancer battle, with her first being diagnosed with breast cancer back in 2015.
After going into remission following treatment, Doherty later revealed in 2020 the cancer had aggressively returned as stage four, with some cancer cells now spreading to her brain.
Doherty said she had kept the news out of the public domain for a year, adding: "I don’t think I’ve processed it. 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.

"But I would say that my first reaction is always concern about how am I going to tell my mom, my husband."
In June this year, she tragically revealed the cancer had metastisized to her brain and is now terminal.
Initially, Doherty largely kept her diagnosis to herself and continued working on the BH90210 reboot. However, one of the few people that she confided in was her co-star Brian Austin Green.

“I had moments of great anxiety where I thought, ‘I can’t really do this,’ and Brian was the one person who - of that group of people that knew - that I told, like, pretty quickly and said, ‘Here, this is what I’m dealing with',” she said.
“So prior to shooting he would always call me and say, ‘Listen, you know, whatever happens, I have your back.’ He would look at me and be like, ‘We got this, kiddo’…so Brian helped me through a lot.”
