Daily aspirin - More benefit than risk?

2018-09-12
Many people take a low dose of aspirin every day to lower their risk of a further heart attack or stroke, or if they have a high risk of either.

While the anticipated benefit is a lower chance of vascular disease, taking daily aspirin is not without danger: for instance it raises the risk of internal bleeding. Hence the important need to discuss beforehand with the doctor, "In my case, doc, should I be taking daily aspirin?"

But this week, the publication of three studies in The Lancet, has added a new benefit to the equation: cancer prevention, and stirred up the pros and cons debate.

In those studies, Professor Peter Rothwell of Oxford University in the UK, a world expert on aspirin, and colleagues, confirm that for people in middle age, a daily dose of aspirin can cut the risk of developing several cancers, with effects starting after only two to three years rather than the ten or so previously thought.
