Legendary Black Sabbath guitarist Tony Iommi has reportedly been diagnosed with lymphoma, according to a statement released Monday, but doctors found the cancer in its early stages so the odds of a complete recovery are good.  Iommi will continue to work with the rest of Sabbath's original lineup for their first album together since 1978, though it is unknown how his illness will impact their plans for a tour, for which many of the dates have already been scheduled.  The band will continue to write and record the record, which will be helmed by Rick Rubin and is expected to be in stores in the fall.
