The 60-year-old TV and film star had an operation in early January and said on his website ‘They took the prostate out,’ before adding ‘So fas as we know it’s all been got.’
Despite confirming that it was ‘an aggressive cancer,’ the formerQI presenter says that it ‘doesn’t seem to have spread.’
In the video on his site, he said: "You have to recover and that's what I've been doing."
"For the moment I'm fit and well and happy and I just wanted to let you know because rumours had started to swirl."
He said his family and "my darling, darling husband" Elliott Spencer had been "just marvellous".
"Here's hoping I've got another few years left on this planet because I enjoy life at the moment and that's a marvellous thing to be able to say, and I'd rather it didn't go away," he added.
According to the BBC, Fry’s condition was given a Gleason Score - a scale used to rate the aggressiveness of prostate cancer - of nine out of 10 before the operation, in which surgeons removed 11 lymph nodes.
"I know it's an old cliché but you don't think it's going to happen to you,’ he added.
