The anti-tumor effect of aspirin: What we know and what we expect

Aspirin has been widely used as an antipyretic analgesic drug. More and more evidences have shown that aspirin may be play some role on anti-tumor. In this article, we reviewed the research history of aspirin in the treatment and prevention of cancer. Many epidemiological and clinical studies have shown that aspirin can reduce the risk of a variety of malignant tumors and reduce cancer mortality. In addition, we discuss the specific mechanisms of aspirin in the anti-tumor effects. It has been found that aspirin mainly depends on the COX pathway and non-COX pathway to inhibit tumor cell growth and to curb tumor development. In this article, clinical studies and anti-tumor mechanism studies published in recent years are reviewed.
