Aspirin Helps in Reducing Cancer Deaths, a Study Finds
By RONI CARYN RABIN
Many Americans take aspirin to lower their risk of heart disease, but a new study suggests a remarkable added benefit, reporting that patients who took aspirin regularly for a period of several years were 21 percent less likely decades later to die of solid tumor cancers, including cancers of the stomach, esophagus and lung.
As part of the new study, published online Monday in the journal Lancet, researchers examined the cancer death rates of 25,570 patients who had participated in eight different randomized controlled trials of aspirin that ended up to 20 years earlier.
