Pauly Shore is still reeling after discovering he had a benign tumor inside his pancreas during a preventive body scan several months ago.

The “Encino Man” star, 57, told fans about his health scare in a Wednesday Instagram video, which captured him right before surgery and several weeks after.

Recording from a hospital bed, Shore explained how he decided to get a preventive scan on a whim, only to learn he had a small tumor that doctors told him could have been in his body for as long as “15 to 20 years.”

“It’s like a devil that’s in me,” he joked to a nurse in his pre-op message. “Get it out.”

Though the tumor didn’t pose an immediate emergency, the actor said his diagnosis had an intense affect on his mental health.
