Last January, the 66-year-old actor revealed that scans had caught a cancerous tumour in his lung early and he had subsequently undergone an operation to have it removed, followed by chemotherapy.
During his chemo, another tumour was discovered in his liver, he said, but luckily, it was unconnected to the lung cancer and treatable.
He had a procedure called TACE to deal with it, which is where the blood supply to a tumour is blocked after anti-cancer drugs are given in blood vessels near the tumour.
Then in May, the star, who played Mickey Pearce in the classic BBC sitcom, announced that he was cancer free and thanked Sir David Jason for his support.
However, on Thursday (12 January), the actor confirmed that his cancer has returned several months after going into remission.
Taking to Twitter, he penned: “I am going home today. Minus half a liver and a tumour that the wonderful Prof Heaton removed last week.
“I kept this under my hat that they’d discovered another primary cancer last year. I am a two person, that’s for sure. High fives to all at Kings College Hospital.”
After revealing the news, Murray was inundated with messages of support on social media.
A social media user tweeted: “Oh Pat, Gutted to read that BUT a positive start for 2023 and I really hope you make a speedy recovery with a clean bill of health for the future.
“Onwards and upwards love, thinking of you and sending love and positivity only.”
“You’ve certainly been through a lot,” another commented. “Best wishes for a speedy recovery.”
A third remarked: “Glad your back home now. Huge thanks to the amazing Prof Heaton and all the staff at King’s College Hospital for taking such great care of you.
“Sending lots of Millwall love and positivity your way!”
