A recent study suggests that taking aspirin daily may help reduce cancer risk by as much as 60 percent. British researchers from the University of Oxford and John Radcliffe Hospital published study results in the journal The Lancet that suggest taking a 75 mg dose of aspirin daily for at least a period of 5 years can reduce the risk of death due to certain cancers from 10 to 60 percent.
The finding was a result of 8 long term studies that involved around 25,000 patients. The studies involved randomized trials of patients taking daily aspirin versus those who took no aspirin. The average duration of the trials took 4 years or longer to ably determine the effect of aspirin to cancer death risk in relation to the period of trial treatment. Post trial follow up for the long term studies were obtained from death certificates and cancer registries.
In the 8 eligible trials, results show that aspirin does indeed provide some benefits when it comes to reducing the risk of certain cancers. The benefits of the low dosage aspirin regimen only seem to show after a period of 5 years since first taking aspirin. In that span of years, deaths due to gastrointestinal cancers decreased by 54 percent. It took longer for other types of cancers to show results.
In a period of 20 years, the patients who took a daily dosage of aspirin had a 60 percent reduction of death due to esophageal cancer. Risk of death due to colorectal cancer decreased by 40 percent. For lung cancer, death risk was reduced to 30 percent while deaths due to prostate cancer decreased by 10 percent.
“These findings provide the first proof in man that aspirin reduces deaths due to several common cancers,” noted the study team in a press release. But Prof. Peter Rothwell further however, added, “these results do not mean that all adults should immediately start taking aspirin.” Aspirin does pose a risk of bleeding when taken. That is why caution must always be taken before taking up a daily aspirin regimen as a means to prevent
