Carly Fiorina topped Fortune‘s Most Powerful Women list for seven years, from its launch in 1998 (when she was heading the biggest division at Lucent Technologies) until 2004, shortly before she was fired from the CEO position at Hewlett-Packard . The news broke today that Fiorina, 54, was diagnosed with breast cancer on February 20 and underwent surgery yesterday at Stanford Hospital.

The buzz around Washington and California lately is that she has been gearing up to run for the U.S. Senate, to vie for Barbara Boxer’s seat in 2010. We at Fortune have come to know Fiorina well over the years. We know what a fighter she is, and we wish her a full and fast recovery.
