Etheridge Fighting Cancer

Rocker undergoes treatment for breast cancer, cancels tour

Melissa Etheridge, 43, has cancelled her upcoming seven-city tour to undergo surgery for breast cancer in Los Angeles, where she lives with her partner, actress Tammy Lynn Michaels.

"I am fortunate to be under a wonderful doctor's care and thankful that this was caught early," said the singer in a statement released yesterday.

Last month, Etheridge released Lucky Live, a CD/DVD of her April performance at New York City's Roseland Ballroom, and she is slated to star as a gay mom in an ABC sitcom.
