Black Sabbath guitarist Tony Iommi has been diagnosed with the early stages of lymphoma, and is currently working with doctors to determine the best possible treatment routine.

WebMD defines lymphoma as “cancer of the lymphatic system, a network of lymph nodes connected by blood vessels that drain waste products and strain cancerous cells from the body.” According to the band’s official statement, Iommi remains “upbeat and determined to make a full and successful recovery.”

Of course the music legend’s health is far and away the most important concern going forward, and while no mention is made of any changes to the newly reunited Black Sabbath’s already scheduled touring plans, currently set to start May 18 in Moscow, it would be certainly be understandable if postponements or delays were announced in the future.

It does seem as though the band is determined to continue work on the first Sabbath album to feature the original lineup (Iommi, singer Ozzy Osbourne, bassist Geezer Butler and drummer Bill Ward) since 1978′s ‘Never Say Die.’ According to the statement, the band will now join Iommi in the UK to continue work on the new Rick Rubin-produced record.
