The Runaways rocker Sandy West has lost her battle with lung cancer. She was 47. West formed the all-girl rock group with Joan Jett, Lita Ford and Cherie Currie, paving the way for other girl power acts like The Bangles and the Go Gos.

In a statement from Jett, the singer says, "I am overcome from the loss of my friend... She was an exuberant and powerful drummer."
