Comedian Rhod Gilbert has announced he is being treated for cancer and will be "disappearing for a while" to focus on his recovery.
The 53-year-old Welsh stand-up shared a message on his official Facebook page thanking the staff at Velindre Cancer Centre in Cardiff, where he is being treated.
Gilbert said that prior to his diagnosis he had been a patron of the centre for a decade but "never imagined" he would become a patient there.
He did not confirm the type of cancer for which he's being treated.
A regular guest on panel shows such as Would I Lie to You?, QI and Mock the Week, Gilbert also hosted the final season of Never Mind the Buzzcocks in 2015.
He said: "As a proud patron of Velindre Cancer Centre, I've trekked the world, hosted chaotic quizzes and star-studded comedy nights.
"I’ve met and made friends with so many inspirational staff, patients and their families. It has been a huge part of my life for the last ten years.
"So while I never imagined that I would be a patient here, I know better than anyone that I am in the best possible hands. The NHS care I’m receiving is incredible.
"I wouldn’t wish this on anyone … but who knows, maybe I’ll come out the other end with a new stand-up show and a 40-minute rant about orange squash."
Gilbert thanked his close friends and family for their support "over the last few weeks and months (and years)".
He added: "I’ll be disappearing for a while and won’t be commenting further, at least not for now, whilst I focus on my recovery."
Gilbert married his long-term partner, writer and comedian Sian Harries, in 2013.
