Chat show legend Sir Michael Parkinson has revealed that he is suffering from prostate cancer.

The 78-year-old told The Sun that he is undergoing radiotherapy for the disease, and that he expects to make a full recovery.

He added that the diagnosis came as a ‘great shock’ – but was determined to remain optimistic.

“Of course mortality is on the mind, but I’m not afraid,” he said.

“My wife Mary has been a tremendous support and while she has been, of course, very upset, she can see how I have approached this.”

He added: “I don’t feel ill.And I will keep working. I have no intention of stopping working.”

Michael also said he was backing a campaign to raise awareness of the disease, in the hope that men would have any suspicious symptoms checked by their doctor.

“I’m not a softy,” he said. “If you show the symptoms of this dreadful disease, get help.

“Men need to get themselves checked. It will save lives.”
