A meta-analysis through 2019 said that there was an association between taking aspirin and lower risk of cancer of the colorectum, esophagus, and stomach. [138] In 2021, the U.S. Preventive services Task Force raised questions about the use of aspirin in cancer prevention.
Aspirin helps prevent blood clots from forming, which is the leading cause of heart attack and stroke, but the drug also carries a risk of bleeding. That risk can outweigh aspirin’s benefits in ...
Finally, aspirin may additionally influence the immune response against cancer cells and block the development of blood vessels that supply nutrients to growing cancer cells.” — Andrew T. Chan ...
Blood thinners are used to prevent clots, these blood thinners have different effectiveness and safety profiles. A 2018 systematic review found 20 studies that included 9771 people with cancer. The evidence did not identify any difference between the effects of different blood thinners on death, developing a clot, or bleeding. [2]
Overall, the risk of developing colorectal cancer over a 10-year period was 1.98% among participants who used aspirin regularly, compared with 2.95% for people who didn’t use aspirin regularly.
Each drug has a benefit-risk profile and balancing the risk of no treatment with the competing potential risks of various therapies should be considered. [49] For people over the age of 65 years old, the balance between the benefits of pain-relief medications such as NSAIDS and the potential for adverse effects has not been well determined.
According to new research, taking aspirin on a regular basis may help reduce the risk of colorectal cancer—especially for people with less-healthy lifestyles.

[1] This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2]
