More evidence that aspirin lowers risk of cancer

MIAMI (AFP) – People who take aspirin regularly have a significantly lower risk of cancer, particularly involving the colon and gastrointestinal tract, according to US research published on Thursday.

The findings in the Journal of the American Medical Association (JAMA) Oncology suggest that aspirin use should complement – not replace – already established preventive screening measures such as colonoscopies.

“We now can recommend that many individuals consider taking aspirin to reduce their risk of colorectal cancer –particularly those with other reasons for regular use, such as heart disease prevention,” said senior author Andrew Chan of the Massachusetts General Hospital.

“Our findings imply that aspirin use would be expected to prevent a significant number of colorectal cancers above and beyond those that would be prevented by screening and may have even greater benefit in settings in which the resources to devote to cancer screening are lacking.”

Previous research has shown that regular aspirin use can help prevent colorectal cancer.

However, the wider effect of aspirin on all cancers was less clear.

So the researchers looked at 32 years worth of data from nearly 136,000 nurses and health professionals who answered health surveys.

People who took either a regular aspirin or a low-dose aspirin at least twice per week showed a three percent lower risk of any type of cancer than those who did not report regular aspirin use.
