Battling cancer, Shannen Doherty appeared at ‘90s Con in Tampa. See the fans’ reaction

For anyone who longs for the days without Instagram, smart phones and reality TV, ‘90s Con in Tampa, Florida, over the weekend, was quite literally a blast from the past.

A bunch of celebs who used to smile at you from posters hung in your bedroom at your parents’ house were right there, in the flesh, at the Tampa Convention Center.

TV stars from shows like “Boy Meets World,” “Charmed,” and “Saved By the Bell” mixed and mingled with music stars like girl group TLC and boybanders N’ SYNC and the Backstreet Boys.

But peak nostalgia was reached Sunday, when “90210’s” Shannen Doherty had a moment at the end of a panel with fellow costars Brian Austin Green, Ian Ziering, Jason Priestley, Jennie Garth, Gabrielle Carteris and Tori Spelling.

The 52-year-old actress, who has been public about her ongoing treatment for Stage 4 breast cancer that has metastasized to her brain, teared up when the cast and audience gave her a standing ovation.

“You guys know how much I love crying constantly, and I do, it seems. So, thank you,” she joked, adding, on a serious note: “I have a fight for my life that I deal with every day.”
