Black Sabbath guitarist Tony Iommi has posted a message to fans at his official website, hinting that his next round of treatments for cancer might be his last for a while. Iommi has had to go back to England every six weeks for treatment ever since being diagnosed with lymphoma in 2012, forcing him and Sabbath to work around both the treatments and the recovery time needed afterward.

Now he has written, "We’ve some good things lined up for the coming year, firstly the Grammys, then some dates in the U.S. and Canada, and in the summer a quick trip round Europe. I should also be finishing my regular treatment and I’m hoping to not get so tired -- all positive.”

Last year, Iommi said that his ongoing treatments and their physical side effects could severely restrict Sabbath's activities, explaining, "I can’t commit to doing another two years or anything like that. I have to play it as it comes now.”

But in his new message, Iommi sounded more upbeat, saying, "After such a brilliant 2013, it's going to be difficult to match it this year but we’ll be having a go." He also thanked his bandmates, producer, management, record label, road crew and assistants for helping the band.
