It’s just been released this morning that Beastie Boys‘ latest tour has been canceled as Adam Yauch (a.k.a. MCA) has just been diagnosed as having a cancerous tumor in his left parotid (salivary) gland. The cancer is considered very treatable, but will require Yauch to undergo surgery and several weeks of treatment.

Yauch said in a press statement, “I just need to take a little time to get this in check, and then we’ll release the record and play some shows. It’s a pain in the neck (sorry, had to say it) because I was really looking forward to playing these shows, but the doctors have made it clear that this is not the kind of thing that can be put aside to deal with later.”
