In the last two decades, it has become clear that exercise plays a vital role in cancer prevention and control (2,5). Courneya and Friedenreich (1) proposed a Physical Activity and Cancer Control Framework that highlights specific phases along the cancer continuum where exercise has a logical role and identifies two distinct periods before diagnosis and four periods after diagnosis with objectives for exercise programs in each phase. There is a growing body of evidence suggesting that exercise decreases the risk of many of cancers (4,5), and data to support the premise that exercise may extend survival for breast and colon cancer survivors are emerging (3).
