Democratic U.S. Senator Ron Wyden has been diagnosed with prostate cancer. Thursday afternoon Wyden made the announcement and plans to have surgery this Monday at John Hopkins Hospital in Baltimore. Wyden was diagnosed with early stage prostate cancer during his annual physical in November. Wyden says that he reviewed all the options with several doctors and decided to take a pro-active approach and have the surgery.  He says thanks to routine screening the cancer was diagnosed very early. Wyden could miss some key votes; he says he scheduled the surgery awhile back anticipating that the Senate would have recessed for winter break.
