Feargal Sharkey has revealed he was diagnosed with prostate cancer.
The A Good Heart singer has urged men everywhere to get tested, sharing that he was given the news after visiting his GP about a sore throat.
The environmental campaigner and former lead singer of punk band the Undertones said the health problem was "resolved" a year ago.
Speaking to the Daily Express, he shared: "About a year and a half ago, I randomly went to see my GP with a sore throat.
"So my doctor, being the beautiful, wonderful, awkward, cantankerous old man that he is, went: 'Oh Feargal, by the way, you're 65 now, I'm going to run the full battery of tests.'
"Two days later, it turns out, I began a journey which led to prostate cancer.
"Thankfully, that's all now been resolved a year ago. But here we are, had it not been for that random visit to my local GP, I would never have known that I was at that point carrying prostate cancer, and if it had not been seen to, it could have been a very different ending and a very different outcome to my life."
Sharkey was the lead vocalist of the Undertones in the 1970s and 1980s, and charted as a solo artist with hits such as You Little Thief in the 1980s.
