Pick an NSAID, Any NSAID
A large study of the 19 different non-steroidal anti-inflammatory drugs (NSAIDs) involving over 300,000 people found they all decreased the risk of colorectal cancer. Taking NSAIDs everyday decreased the risk of colon cancer by 28 percent but monthly use cut the reduced risk in half. People with family members who had it lowered their risk by 28 percent when they took an NSAID every day, but only by 11 percent when taken weekly. Aspirin reduced the risk of rectal cancer by 62 percent but did not affect the risk of developing colon cancer while non-aspirin NDSAIDs lowered the risk of colon cancer by 56 percent but did not lower rectal cancer risk. There were several limitations to the study and researchers want to understand which types of colon cancer will benefit the most from aspirin.
