Labour’s Kevin Brennan said he is recovering from prostate cancer surgery last week.
He tweeted that he was “recovering very well and needing no further treatment”.
The Cardiff West MP said the surgery was carried out at the University Hospital of Wales, where the staff he thanked for “incredible skill, professionalism, dedication and humanity”.
“I was a healthy man and had no symptoms prior to my diagnosis,” he said.
“Over 50, ask your GP for PSA tests and scans if indicated as I did – early diagnosis means you can monitor changes and intervene only if needed necessary.”
He said he will be working from home for the next few weeks.
The 62-year-old finished with: “Seize the day – cherish your family and loved ones – help others – be kind and enjoy life!”
Prostate cancer is the most common disease in UK men and around one in eight will develop it in their lifetime.
It mainly affects men over the age of 50, and the risk increases with age. The risk is also higher for black men and those with a history of prostate cancer in their families.
Many men with early-stage prostate cancer do not develop symptoms, but things to look out for include changes in the way you urinate.
Examples include a weak flow, difficulty initiating or emptying the bladder, and the need to have a bowel movement more often – especially at night.
