NEW YORK — Beastie Boy Adam Yauch has what is described as a “very treatable” cancerous tumor in his salivary gland.

An announcement came Monday from the group, which is canceling its tour dates and postponing an album release.

A statement says the tumor was found early. It’s confined to one area and is considered very treatable.
