Secretary of State Robin Carnahan hopes her struggle with breast cancer prompts other women to have breast cancer screenings. Carnahan was diagnosed after discovering a lump in her breast. Chemotherapy treatment will begin soon, followed by surgery and radiation. Carnahan spokesman Stacie Temple says Carnahan’s prognosis is excellent, primarily because she caught the cancer early. She hopes the publicity generated by her diagnosis spurs other women to go to the doctor. Carnahan won her first run for political office when she won the Secretary of State’s race in 2004. She is the daughter of the late Governor Mel Carnahan and former US Senator Jean Carnahan. Her brother is St. Louis area Congressman Russ Carnahan.
