In a video posted on the band’s official website earlier today, Adam “MCA” Yauch of the Beastie Boys revealed that he has been diagnosed as having a cancerous tumor in his left parotid (salivary) gland. Fortunately, because it was caught early, doctors believe it is very treatable, though Yauch will need surgery and several weeks of additional treatment.

As a result, the Beastie Boys have canceled all upcoming concert appearances, including scheduled headlining spots at Lollapalooza, All Points West and the Austin City Limits Festival. Furthermore, the group has decided to push back the release of its forthcoming record, Hot Sauce Committee Part 1.

More as it becomes available.

We’d like to wish Yauch the speediest of recoveries. He is in our thoughts.
