Tony Iommi believes he was saved by music during his battle with cancer.
The 78-year-old Black Sabbath guitarist was diagnosed with non-Hodgkin lymphoma back in 2012 and underwent months of gruelling treatment while working on the band's 2013 album 13 with the rocker flying back and forth between the UK and Los Angeles - and he's convinced throwing himself into making the record helped him through the difficult time.
