Abstract:A large number of studies show that aspirin and other non-steroid anti-inflammatory drugs (NSAID) have chemopreventive effects on several cancer types, and more specifically in colorectal cancer. Aspirin can help prevent colon cancer, which has the specific advantage ofdrug prophylaxis. Studies found that aspirin play the different roles on high-risk, moderate-risk and low-risk populations in time and dose. There is limited evidence about the influence on incidence of adenoma among the general risk populations.
