(Buffalo) The office of Jack Kemp says the former congressman and Bills QB has been diagnosed with cancer. A statement issued in Buffalo, N.Y., says Kemp is undergoing tests to assess the origin of the disease and the best treatment. The statement issued Wednesday did not disclose the type of cancer. Kemp, 73, says he will continue to serve as chairman of his Washington-based Kemp Partners consulting firm and will remain involved in charitable and political work. After his football career, Kemp represented western New York for nine terms in Congress. He ran unsuccessfully for president bid in 1988, then later was President George H.W. Bushs housing secretary and ran for vice president as Bob Doles running mate. Kemp quarterbacked the Bills to the old AFL Championship in 1964 and 1965.
