There’s more evidence on the benefits of Aspirin. According to two studies, taking aspirin every day may significantly reduce the risk of many cancers and prevent tumors from spreading.
Researchers at Oxford University found that after three years of daily aspirin use, the risk of developing cancer was reduced by almost 25 percent when compared with a control group not taking aspirin. After five years, daily aspirin reduced the risk of dying of cancer by 37 percent.
In addition, a different study found that a daily dose reduced the risk of metastatic cancer by 36 percent and the risk of some common solid cancers including colon, lung and prostate cancer — by 46 percent.
The findings add to a body of evidence suggesting that cheap and widely available aspirin may be a powerful if overlooked weapon in the battle against cancer. But the research also poses difficult questions as regular doses of aspirin can cause gastrointestinal bleeding and other side effects. Past studies have suggested that the drawbacks of daily use may outweigh the benefits, particularly in healthy patients.
