Lloyd Webber, 61, said in a health diary published on his website that he noticed the first symptoms of his cancer last summer and underwent an operation to remove his prostate gland after a biopsy came back positive.

He was told the cancer had been caught early and the treatment was successful, but he then battled an underlying e-coli infection that had been there all along.

“If that infection had been found and cured, I could have been blissfully unaware that I had a cancerous tumor that was on the verge of breaking loose around the rest of my body. I could have thought that my frequent peeing was due to a weak bladder. I have been bloody lucky,” wrote Lloyd Webber.

“I say to every red-blooded male, if you do begin to have a problem down under, however embarrassing, go to your GP at once. Even if you don’t have any symptoms, if you are over 50 get regular PSA (prostate specific antigen) tests.”

Lloyd Webber, the composer behind hit musicals including “Jesus Christ Superstar,” “Cats” and “Starlight Express,” is staging a sequel to “The Phantom of the Opera” called “Love Never Dies” that is due to open in London in March this year.

He has also just kicked off a search for Dorothy to star in his West End production of “The Wizard of Oz” with his search to be the topic of a BBC television talent show.
