Led by researchers at the University of New South Wales, a new study looked at six Australian cohort studies, which included a total of 214,536 women, to investigate if changing certain lifestyle habits could possibly prevent future cases of pre-menopausal and post-menopausal breast cancer.

The findings, published in the International Journal of Cancer, showed that for pre-menopausal women, regular alcohol consumption explains 12.6% of breast cancer cases in the next decade, and using oral contraceptives for five years or more accounts for 7.1%.
