Lifestyle Affects Breast Cancer Risk – Part 2 of 3
The model predicted that improvements in modifiable chance factors would result in a 1,6 percent reduction in the average 20-year absolute risk in a general population of women aged 65; a 3,2 percent reduction among women with a unambiguous family history of breast cancer; and a 4,1 percent reduction among women with the most non-modifiable risk factors. The authors pointed out that the predicted changes in lifestyle to achieve these goals – such as prior and current drinkers becoming non-drinkers – might be overly optimistic.
But, the findings may help in designing programs meant to encourage women to make lifestyle changes, according to the researchers. For example, a 1,6 percent unrestrained risk reduction in a general population of one million women amounts to 16000 fewer cases of cancer.
