According to his representative, Diamond, who was best known for his portrayal of Screech on the much-loved sitcom, Saved by the Bell, died on Monday morning just weeks after he was diagnosed with cancer.

We're told Dustin's family has a history of cancer -- his mother died of breast cancer -- but it's unclear what kind of cancer they suspect in his case." It was later confirmed that Diamond was battling stage four small cell carcinoma, a form of cancer, and was undergoing chemotherapy in a bid to prolong his life. The actor was most famous for playing Screech in Saved By The Bell but he wasn't part of the cast in Peacock's recent revival of the NBC sitcom.
