Beastie Boy and upstart independent-film distributor Adam Yauch has been diagnosed with a cancerous tumor in his left salivary gland, he announced today in New York. He is expected to undergo surgery immediately and make a full recovery. Yauch, who turns 45 on Aug. 5, disclosed the news in a video with his bandmate Adam Horovitz; it accompanied an announcement that the Beasties had canceled its summer tour itinerary, including performances at Lollapalooza, All Points West and a September date at the Hollywood Bowl. Meanwhile, business at Oscilloscope Pictures, which last week acquired the Oscar hopefuls No-Impact Man and The Messenger, will continue without interruption. We at Movieline wish Yauch all the best and hope to see him healthy at the Toronto Film Festival in September. [THR]
