According to recent reports, former Hewlett-Packard Co. Chief Executive Carly Fiorina has been diagnosed with breast cancer. She found out about the disease on February 20, the day before she appeared at a GOP convention in Sacramento.

Carly Fiorina underwent surgery at Stanford University Hospital Monday for breast cancer, her chief of staff said Monday evening, according to the San Francisco Chronicle.

Fiorina is “doing great” and has an excellent prognosis for a full recovery, Mercury News cited Deborah Bowker as saying. She is expected to start a course of chemotherapy and intends to restrict her activities and air travel over the next few months, according to Bowker. During the meeting, she urged the party to offer voters a positive agenda of lower taxes and less government.

The “most powerful woman in business,” as she was named by the “Fortune’ magazine in 1998, served as an executive vice president at AT&T and organized the initial public offering of Lucent. The event became the most successful initial public offering in United States history up to that point in time.

Carly Fiorina, 54, served as an adviser to Sen. John McCain’s presidential campaign and has been considered a possible candidate for the seat held by California Democratic Sen. Barbara Boxer. She now sits on several corporate boards of directors, is an Honorary Fellow of the London Business School, and is a member of the Board of Trustees for the Massachusetts Institute of Technology.
