A daily dose of aspirin "is the most important thing we can do to reduce cancer after stopping smoking and reducing obesity", a leading professor said.
Professor Jack Cuzick, head of the centre for cancer prevention at Queen Mary University, said he thought GPs should recommend the drug, adding:
It has long been known that aspirin - one of the cheapest and most common drugs on the market - can protect against certain types of cancer.
But until our study, where we analysed all the available evidence, it was unclear whether the pros of taking aspirin outweighed the cons.
Whilst there are some serious side effects that can't be ignored, taking aspirin daily looks to be the most important thing we can do to reduce cancer after stopping smoking and reducing obesity, and will probably be much easier to implement.
