TULSA -- A spokesman for Oklahoma Sen. Tom Coburn says the lawmaker has had a recurrence of prostate cancer and is undergoing further evaluation and treatment.
Spokesman John Hart said in a brief statement to The Associated Press on Tuesday that the 65-year-old Republican will be out for the rest of the week but will be back "as soon as he's able, hopefully next week."
Coburn was treated for the same thing in 2011 and returned to work within days. He's also survived malignant melanoma and colon cancer.
Coburn's fellow U.S. senator from Oklahoma, Jim Inhofe, underwent emergency quadruple bypass surgery in Tulsa last month. Inhofe's campaign manager says the 79-year-old senator spent his first day back in Washington on Monday.
