An Aspirin a Day to Prevent Colon CA

Several studies have evaluated the correlation between low-dose aspirin and NSAID use and the development of colorectal cancer. In 2007, the U.S. Preventive Services Task Force (USPSTF) recommended against the use aspirin for the prevention of colorectal cancer in most adults. However, there is mounting evidence that daily, long-term aspirin use may prevent colorectal cancer in patients aged 50-69. Could something as simple as an aspirin a day prevent colon CA?
