Study Links Adult Dose Aspirin To Moderate Drop In Cancer RiskTopics: Medical Science News
A new American Cancer Society study finds men and women who used adult-strength (325 mg or more) aspirin (acetylsalicylic acid) daily for five or more years had an approximately 15 percent lower rate of developing any cancer than those who did not use aspirin. Specific cancers that occurred less commonly in long-term daily aspirin users included colorectal cancer, prostate cancer, and possibly breast cancer. A previous study published in 2005 found that low-dose aspirin (about 100 mg) every other day did not lower risk of any cancer, suggesting that higher doses may be required to help prevent cancer:
During 12 years of follow up, nearly 18,000 men and women in the cohort were diagnosed with cancer. Those who reported daily use of adult-strength aspirin for at least five years had an approximately 15 percent relative reduction in overall cancer risk. The decrease was not statistically significant in women. The researchers looked at specific cancer sites and found men who used aspirin daily had a 20 percent lower risk of prostate cancer and that men and women who used aspirin had a 30 percent reduction in the risk of colorectal cancer. Aspirin use had no effect on the risk of other cancers studied: lung cancer, bladder cancer, melanoma, leukemia, non-Hodgkin lymphoma, pancreatic cancer, and kidney cancer. The researchers also found aspirin use for less than five years was not associated with decreased cancer risk.More here.
