Researchers in Scotland say very low-dose aspirin, taken regularly, may ward off bowel cancer. The researchers at the University of Edinburgh in Scotland say the crucial finding is that high doses of aspirin, taken for a long time, are not needed to help ward off bowel cancer. This finding held true irrespective of lifestyle choices, age, diet, weight and poverty. In a statement, corresponding author Malcolm G. Dunlop and colleagues said this is the first study to demonstrate a protective effect against colorectal cancer associated with the lowest dose of aspirin – 75 mg per day – after only 5 years use in the general population. The study finds after a year, taking low-dose aspirin regularly was associated with a 22 percent reduced risk of developing bowel cancer and the magnitude of the reduction was cumulative, rising to 30 percent after five years.
