According to a new study, daily dose of aspirin or other "nonsteroidal anti-inflammatory drug" (NSAID) significantly improves the test results of men with prostate cancer.

By taking aspirin, the level of prostate specific antigen (PSA) getting lower than the level of clinical suspicion. This shows that it is helping the body to fight the disease.

PSA test is a method used to measure the level of prostate cancer, with higher blood PSA levels suggesting a higher chance of having prostate cancer.

Dr. Jay H. Fowke and his associates from Vanderbilt University in Nashville collected data from 1,277 men older than 40 years who were referred for a biopsy of the prostate. About 46% of the men reported taking an NSAID, in which 37% took aspirin.

Researchers found that the men using aspirin have 9% lower PSA levels than those who were not using aspirin. Fowke presented the report at an international conference of the American Association for Cancer Research in Washington DC.

Fowke and colleagues wrote, “These results may suggest that aspirin use decreases the ability to detect prostate cancer and may contribute to prior investigations reporting a protective association between NSAID use and prostate cancer risk.”

However, scientists are still not sure that aspirin is really protective against the disease, so more study is needed.
