Researchers have found that taking a low dose of aspirin daily may reduce the risk of developing cancer, opening a new debate over the benefits of this widely used medication.

Aspirin, one of the most common drugs in the world, is typically used as a pain reliever and fever reducer. Previous studies have indicated its potential in lowering the likelihood of colon cancer. A new Australian study, which followed nearly 10,000 individuals aged 71 to 77 over five years, revealed that taking 100 mg of aspirin daily reduced cancer risk by 15%.
The results showed that the protective effect of aspirin was greater among non-smokers, people with a lower body mass index, and those with a family history of cancer. The benefit was particularly noticeable in individuals with a condition called Clonal Hematopoiesis of Indeterminate Potential (CHIP), an age-related change in blood cells that increases the likelihood of tumors.
Researchers noted that the presence of CHIP in roughly 10% of blood cells may indicate a clear benefit from aspirin intake, as it seems to influence inflammatory pathways linked to cancer. However, they stressed that more research is needed before recommending widespread use, especially since the study focused only on healthy elderly individuals.
Timing of aspirin use may also be important, as other studies suggest that starting it at a younger age could produce different results than starting later in life.
Despite these positive indications, experts warned about potential risks of long-term aspirin use, such as stomach ulcers and bleeding. They emphasized that any preventive use of aspirin for cancer should carefully weigh benefits against possible complications.
Aspirin is already widely used to reduce the risk of heart attacks and strokes, especially in patients with coronary artery disease. Nevertheless, evidence regarding its long-term efficacy and safety remains limited, highlighting the urgent need for further studies.
