Beastie Boy Adam Yauch has been diagnosed with cancer of the salivary gland and will undergo treatment, Billboard reports. The surgery and radiation forced the group to cancel summer tour dates and postpone the release of a new album. The outlook, though, is good. “It’s a pain in the ass, but … very treatable,” says Yauch, aka MCA. “It’s only localized in this one area, and it’s not in a place that affects my voice.” (More Beastie Boys stories.)
