Saved By The Bell star Dustin Diamond has been diagnosed with stage four cancer, his representatives have confirmed.

The 44-year-old was hospitalised in Florida last weekend after complaining of pain all over his body - and at the time he suspected cancer as the cause due to his family health history.

Following tests, his team posted an update on his official Facebook page which read: "At this time we can confirm that Dustin does have cancer. Dustin will disclose more information once it is available and a plan moving forward is made."

Confirming that his cancer is stage four, meaning that it has spread to multiple parts of his body, Diamond's spokesperson told EW: "He's undergoing chemo so he will be there at least another week and then we will figure out when he gets to come home.

"By next week, we'll have a much better understanding of the severity of his condition and what treatments he will need so that he's comfortable."

Diamond appeared as Screech in Saved By The Bell and multiple spinoffs for 12 years.
