Adam "MCA" Yauch has a cancerous tumor in his left salivary gland and an adjacent lymph node. In an online video, the Beastie Boy revealed that the tumor is located in his neck, so it won't affect his vocal cords, and is "very treatable in most cases." The rap group has canceled their upcoming fall concerts while Adam recovers from surgery and undergoes radiation treatments. "I apologize to everybody for anyone who's made plans or was psyched to come to these shows that are coming up," he said, adding: "We'll be back doing this, so that's what's up." The group is also pushing back the release of their latest album, Hot Sauce Committee Part 1, which was going to be released on September 15.
