Only Fools and Horses actor Patrick Murray has been diagnosed with cancer.
The Mickey Pearce actor, 65, revealed on Twitter that he has a tumour in his lung.
He wrote: "Naturally I wanted to keep my own health problems private, but failing to fully endorse this ad would be selfish.
"Thanks to my ultrascan I have a fighting chance.
"It showed my organs needed further investigation and tumours were spotted.
"This led to a PET scan which covers a much larger area.
"To my wonderful surprise these lesions were not cancerous but the scan did find an early-stage cancerous tumour in my lung. This has since been removed.
"I am tweeting now, which wouldn’t be the case if I hadn’t had the ultrasound all those months ago.
"A lot of people put these symptoms down to age and the discomfort to simply having a weak stomach.
"Please don’t ignore it if it persists.
"As for me, and thanks to the NHS, I can now see the same beautiful horizon as you."
Patrick appeared in a total of 20 episodes of Only Fool And Horses, which also starred David Jason as Del Boy and Nicholas Lyndhurst as Rodney Trotter.
Since the show finished in 2003, Patrick has landed roles in big-screen productions, including The Firm and Curse Of The Pink Panther.
After a couple more years of acting, Patrick eventually retired and became a taxi driver in Kent.
He was then forced to quit working altogether amid his battle with Chronic obstructive pulmonary disease.
The condition causes a large number of breathing difficulties for those effected.
Patrick married his wife Anong, 36, in Pattaya, Thailand in 2016.
The lovebirds, who share five-year-old daughter, Josie together, were dragged into a visa row after the Home Office denied his wife and daughter's application to come to the UK in 2017.
At the time, he appeared on Loose Women to discuss the issue.
Patrick told the panelists: "I wanted to get her a visa but it was hard so I had to come back here.
"Being out of the industry for so long, the work dried up so I went back to driving an executive car, a Mercedes, to do it.
"I only saw my baby on the phone for two years, I was a Skype dad."
Thankfully, the actor was reunited in Britain with his family in 2018 after the successful battle with the Home Office.
