As for what type of cancer, they said the actor will release a statement when a formal diagnosis has been made. They called the diagnosis “serious” and said he has started chemotherapy.
“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,” his rep tells EW. “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 is feeling “fine” today, according to the rep, and better than when he was admitted to the hospital.
