Feargal Sharkey has revealed he has been diagnosed with prostate cancer after a routine visit to the doctor for a sore throat.

The former rockstar turned water campaigner says he is now 'doing very well' and has vowed to 'continue the fight' for clean rivers following the health scare that was 'resolved' a year ago.

For the first time, the Undertones frontman, 66, has shared his experience publicly, hoping to motivate other men to undergo cancer screenings.

He revealed that around a year and a half ago, he went to see his GP for a sore throat.

Knowing him well, the doctor insisted on running a full set of tests, noting Feargal's age and sensing something more serious might be going on.
