Taking aspirin every day can reduce the chance of developing or dying from bowel and stomach cancers, a review of all available evidence suggests.
Prof Jack Cuzick, at Queen Mary University of London, who led the research, urged all healthy people aged 50 and above to consider taking a small dose (75mg) of the drug every day for a decade.
Researchers predicted if 1,000 individuals aged 60 took the drug for 10 years, a further decade later there would be:
- 16 fewer deaths from cancer
- One fewer death from heart attack
- Two extra deaths from bleeding
Individual risks
They found benefits continued even when people stopped taking the drug, but say it is unclear exactly how long people should use it for.
As the risk of internal bleeding rises as an individual gets older, they suggest a cut-off point of 10 years.
There is still uncertainty whether other doses of the drug could offer more protection.
Aspirin's well known possible side-effects include bleeding in the stomach and the brain.
Experts warn anyone at high risk of bleeding, including people with blood disorders who take blood thinning medication, or are frequent smokers or drinkers, are more likely to suffer these side-effects.
They recommend anyone considering daily medication should speak to their doctors to discuss individual risks.
