 Former Minnesota Senator Norm Coleman says he is being treated for lung cancer. The 68-year-old Republican announced his condition Tuesday in a posting on Facebook. It comes about two and a half years after he was diagnosed with throat and neck cancer. Coleman underwent surgery, chemotherapy and radiation after his initial diagnosis. He had eventually been pronounced cancer-free. Coleman says he has never felt in better shape and he has hopes and prayers for a very long time. Coleman served a single term in the U.S. Senate before being defeated by Democratic Senator Al Franken in 2008 in a race that required a months-long recount. Coleman is now a lobbyist in Washington.
