What do we know about taking aspirin to prevent cancer?
A number of studies have suggested aspirin may protect against cancer. Latest work in The Lancet that looks at 51 studies involving over 77,000 participants suggests aspirin not only reduces a person's risk of developing cancer but could also help stop cancers spreading around the body. Cancer death rates were also significantly lower among people taking aspirin.
Who should take it daily?
Experts say there is still not enough evidence to recommend that fit and healthy people take aspirin as a precaution against cancer. Similarly, healthy people are not advised to take it to prevent heart disease because the risks of dangerous side effects, although small, outweigh the benefits.
Low-dose daily aspirin is only recommended for those considered to be at risk of having a heart attack or stroke.
But experts say it is worth exploring whether some cancer patients, such as those with bowel cancer, might benefit from daily aspirin.
Anyone considering taking aspirin is advised to talk to their doctor first.
