Stephen Fry has opened up about his prostate cancer diagnosis.

The 60-year-old actor and LGBTQ activist revealed that he was diagnosed with the disease just before Christmas when he went to get a flu jab, and his doctor recommended a check-up.

“For the last 2 months I’ve been in the throes of a rather unwelcome and unexpected adventure,” he wrote on Twitter. “I’m sorry I haven’t felt able to talk about it till now, but here I am explaining what has been going on.”

The former QI host went into more detail about his diagnosis and treatment in an emotional YouTube video.

“One option was radiotherapy but it’s a long process,” he explained. “The other was to get rid of the prostate by sending little robots in through tiny holes in the stomach.

“They took the prostate out, [and] they took out eleven lymph nodes. It was an aggressive little bugger.

“In case you’ve been wondering why I’ve been out of the public eye – I’m sure you haven’t – I have been keeping my head down as much as possible because obviously you want to get better.”

He confirmed that the operation was a success, adding: “So far as we know, it’s all been got.”
