Women’s Health Study
Aspirin has many uses, from easing a headache or cooling a fever to preventing heart attacks and the most common kind of stroke. It may be time to add “preventing colorectal cancer” to the list. New results from the Women’s Health Study, a clinical trial that evaluated the benefits and risks of low-dose aspirin and vitamin E among nearly 40,000 women, show that aspirin reduces the risk of developing colorectal cancer by 20%. The effect isn’t immediate, but instead takes ten to 20 years to be seen. Aspirin isn’t without its drawbacks, including gastrointestinal bleeding and ulcer formation. Both occurred slightly more often among women taking aspirin. Although the Women’s Health Study results sound promising, don’t go reaching for the aspirin bottle just yet. Taking aspirin—and any other drug—is really a balancing act between benefits and risks.
