Former U.S. Sen. Norm Coleman has announced he's cancer-free.
Doctors told him right away his cancer was serious, but "very treatable."
According to KSTP, Coleman participated in a clinical trial at Mayo Clinic – it reduced the usual seven weeks of treatment to two weeks. He told the station he's the 52nd patient to try it.
Coleman served as the mayor of St. Paul from 1994-2002. In 2002, the Republican ran for the U.S. Senate and won, representing Minnesota from 2003-2009.
In 2008, Coleman narrowly lost to current Sen. Al Franken, after a recount that took months to complete.
