Shannen Doherty’s former “Beverly Hills: 90210” castmate has given fans a positive new update on her health.

Ian Ziering opened up about Doherty’s strength in a recent interview with E! News.

“You know, Shannen is so resilient,” said the actor. “If I was ever going to war, I would want her on my side, because that woman is a fighter and she gets it done.”

He continued, “Knowing Shannen, she’s got her finger on the heartbeat of whatever the cutting-edge science is. I’m really not too worried about it because she’s doing great.”

Meanwhile, Jason Priestley also addressed the actress’s cancer battle in an interview with Australia’s Studio 10.

Doherty revealed in February that she has stage 4 terminal cancer, telling “Good Morning America” at the time, “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.”

The 49-year-old actress was first diagnosed with cancer in 2015 and had been in remission until the disease returned.
