Long-term regular aspirin use is also associated with reduced risk of obesity- and inflammation-associated cancers, particularly colorectal cancer (CRC) (2,3). Numerous follow up trials have consistently demonstrated significant reductions in risk in GI cancers – the NIH-AARP (4), the Nurses Health Study (5) and the Health Professionals Follow-up study (6,7).…
