Alcohol, diet, and risk of breast cancer... [including commentary by Timothy J Key and Gillian K Reeves].

The article reports the separate studies on whether postmenopausal women who increase their alcohol intake over five years have higher risk of breast cancer and lower risk of coronary heart disease than those who maintain a stable alcohol intake, and whether the consumption of fruit and vegetables in adolescence increases the risk of breast cancer in premenopausal and postmenopausal women. Based on the result, higher consumption of fruits can lower the risk of breast cancer.
