Singer-songwriter and former rodeo champion Chris LeDoux has been diagnosed with cholangiocarcinoma, a slow-growing malignancy of the bile duct. LeDoux announced Thursday (Nov. 4) that he has cancelled three shows while undergoing radiation for cancer. In 2000, LeDoux was diagnosed with a liver disease that eventually required him to undergo a liver transplant. A spokesperson said Monday (Nov. 8), "Chris will begin treatment in about a week and a-half. The prognosis looks good."
