In 2012 the musician was diagnosed with lymphoma but in August this year (16) the musician revealed the cancer had gone into remission.

Although he's battled back well from the disease the Paranoid musician, 68, says he will take time out from preparing for Black Sabbath's 2017 tour to have surgery on his throat to ensure his cancer has not returned.

"I went for a check four weeks ago and the doctor said that, at the moment, there's no activity where I had the cancer before - but there is activity in the throat," he told the Irish Times.

"When I get back to England I have to have an operation to remove this thing at the back of my nose. The doctors found a lump and we don't know if it's cancer or what. But I feel okay at the moment."

Tony explained how receiving his original cancer diagnosis "knocked him for six" but made him realise he has to make more time for family life rather than constantly being on the road.

"It really did change my life as far as what I have to do now," he added. "I have to live what life I’ve got because I have been on the road nearly 50 years. I need to be at home more and I need to pay more attention to my friends and family."

Black Sabbath return to the road on 17 January (17) with a concert at the Lanxess Arena in Cologne, Germany.
