I get the Ozzy Osbourne newsletter via email which keeps you posted of his events, etc. Yesterday's read:

Sharon Osbourne has been diagnosed with a
treatable form of cancer. Mrs. Osbourne
underwent surgery this afternoon and is
expected to make a full recovery. She has
the loving support of her husband and three
children who are by her side at this time.

Well-wishers may send their thoughts to
Sharon via the Osbourne's P.O. Box:
