The case for using aspirin to prevent cancer continues to build, particularly if people are at increased risk of the disease.
Three new studies led by researchers at Oxford University also raise the possibility that a daily low dose of the drug could be effective, not just as a preventative measure, but as an additional treatment for those with cancer.
It follows the finding that aspirin can reduce the chances of tumours spreading to other parts of the body.
The three papers by Professor Peter Rothwell of the Nuffield Department of Clinical Neurosciences and colleagues are published today, two in the medical journal The Lancet and the other in The Lancet Oncology.
Professor Rothwell says: ‘We are not at the stage of recommending aspirin use in everybody, but the guidelines on use of aspirin in the healthy middle-aged population certainly need to be updated in order to take into account the effects on the risk and outcome of cancer as well as on the risk of heart attacks and strokes.’
