Adam Yauch, better known as MCA, released some sad news to his fans via their website yesterday. The 44-year-old rapper announced that a cancerous lymph node was found in his left parotid (salivary) gland. He discovered it as a lump growing several months ago. His prognosis is excellent, and because it has not metastasized, it will be easily treatable with surgery and radiation. In addition (and relief to fans everywhere), it is not in an area where his vocal cords will be affected.

As a result, the Beastie Boys’ summer tour dates have been cancelled, and will also prevent the release of their newest album Hot Sauce Committee Part I.
