Benefits and Risks of Daily Aspirin Use
Benefits of Daily Aspirin Use
Reduction in Cancer Risk
Daily aspirin use has been shown to significantly reduce the risk of several types of cancer, particularly gastrointestinal cancers. Studies have demonstrated that long-term aspirin use (5 years or more) can lower the risk of colorectal cancer and other gastrointestinal cancers, with benefits becoming apparent after 5 years of continuous use . Additionally, aspirin use has been associated with a reduced risk of ovarian cancer, especially among daily users of low-dose aspirin.
Decrease in Cancer Mortality
Aspirin not only reduces the incidence of cancer but also decreases cancer mortality. Research indicates that daily aspirin use can lower the long-term risk of death due to cancer, with significant reductions observed after 5 years of use . The benefits are particularly notable for adenocarcinomas, a type of cancer that includes many gastrointestinal cancers.
Cardiovascular Benefits
In addition to its cancer-preventive properties, daily aspirin use is well-known for its cardiovascular benefits. Aspirin helps prevent vascular events such as heart attacks and strokes by inhibiting platelet aggregation. This dual benefit of reducing both cancer risk and cardiovascular events makes aspirin a valuable prophylactic agent.
Other Health Benefits
Daily aspirin use has also been linked to a reduced risk of fibrosis progression in patients with nonalcoholic fatty liver disease (NAFLD). Regular aspirin users showed significantly lower odds of developing advanced fibrosis compared to non-users.
Risks of Daily Aspirin Use
Gastrointestinal Bleeding
One of the primary risks associated with daily aspirin use is gastrointestinal bleeding. Studies have consistently shown that aspirin increases the risk of major extracranial bleeds, including gastrointestinal bleeding and peptic ulcers . The risk of bleeding is particularly high during the initial years of aspirin use but tends to diminish with prolonged use.
Peptic Ulcers
Daily aspirin use is also associated with an increased risk of developing peptic ulcers. This risk is dose-dependent, with higher doses of aspirin leading to a greater likelihood of ulcer formation.
Stroke
While aspirin is beneficial in preventing ischemic strokes, it can increase the risk of hemorrhagic strokes. This risk must be carefully weighed against the potential benefits, especially in individuals with a higher predisposition to bleeding.
Conclusion
Daily aspirin use offers significant benefits in reducing the risk and mortality of several cancers, particularly gastrointestinal cancers, and provides cardiovascular protection. However, these benefits must be balanced against the risks of gastrointestinal bleeding, peptic ulcers, and hemorrhagic strokes. The decision to use daily aspirin should be made in consultation with a healthcare provider, considering individual risk factors and health conditions.
