Norm Coleman has cancer.
The former U.S. Senator, who represented Minnesota from 2003-2009, wrote in a private Facebook post Monday he was diagnosed with throat cancer, MPR News reports.
The 66-year-old called it "very treatable" while noting the prognosis is "extremely positive," the Pioneer Press writes.
He was diagnosed after having a sore throat for a long period of time, then noticing a lump on his neck, the Star Tribune writes.
He's being treated at the Mayo Clinic, KSTP notes, but expects to continue working throughout.
Prior to his stint as a U.S. lawmaker, Coleman served as mayor of St. Paul from 1994-2002. He ran for the U.S. Senate in 2002 on the Republican ticket, defeating Walter Mondale – a replacement for incumbent Sen. Paul Wellstone, who died in a plane crash just days before the election.
Coleman very narrowly lost to current Sen. Al Franken in the 2008 election, after a recount that took months to complete.
