The former Monty Python trouper says it was "incredible luck" that he was diagnosed very early on in the stages of bowel cancer, The Mail on Sunday reported.
"They stuck a camera inside me and found a tumor. I was taken straight into hospital to have it removed and I recovered extremely quickly after that," he said.
Now, after undergoing both surgery and chemotherapy, he says he is fully recovered and spending time with his 23-year-old girlfriend, Anna Soderstrom.
"I'm in great health and great spirits. I feel incredibly lucky that the illness was spotted so early," he said. "I urge all men over the age of 50 to go for a routine colonoscopy. This would save lives. Colon cancer is incredibly common and you don't necessarily have any symptoms; you don't feel ill."
