The 44-year-old Screech actor has been in the hospital since over the weekend. "Our sources say his medical team is concerned it's cancer, and they're conducting a biopsy to get answers," reports TMZ. "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."
