Yesterday the press reported on a recent series of studies published in the Lancet, suggesting that taking a baby aspirin once a day can significantly reduce both the risks of cancer, and the risk of spreading. Click here for a summary. Here's what the Lancet says:
Aspirin to prevent and treat cancer
A collection of three papers by Rothwell and colleagues add to the
growing evidence base suggesting that daily aspirin can be used to help
prevent and possibly treat cancer. In the first Article
the authors studied individual patient data from 51 randomised trials
of daily aspirin versus no aspirin to prevent vascular events such as
heart attacks. A second Article reports the effect of aspirin on cancer metastasis. Finally, the third Article, published in The Lancet Oncology,
also looked at aspirin’s effect on metastases, this time using a
systematic review of observational versus randomised trials. The three
papers are discussed further in a Comment.
I'll be asking my doctor whether I should start taking an aspirin a day, since one of the studies suggests that people who take low doses of aspirin regularly and who already have cancer reduce the risk of metastasis—that is, the spread of that cancer to other body parts—by 55 percent.
