Tony Iommi says his cancer treatment hasn't stopped him from writing almost every day with Black Sabbath.
The guitarist was diagnosed with lymphoma in January, forcing the band to cancel tour plans and move production of their new album to the UK where he would receive treatment for his illness.
He updated fans with a statement on his site:
"Well, I've had the last dose of chemotherapy so hopefully my body will start to get back to normal soon, the steroids were the worse [sic]. I've now got three weeks of radiotherapy coming up which I'm told can be very tiring so we'll see.
"A big thanks to Ozzy and Geezer for coming over to England, it was a big incentive for me, we managed to work most days and have some great new tracks."
Despite scrapping their tour plans, with European festival dates being replaced by Ozzy + Friends, Black Sabbath is still scheduled to headline Download Festival in the UK.
Meanwhile, it appears that Bill Ward is yet to re-negotiate with his former bandmates, after turning down a contract to join their latest reunion.
