ADVERTISEMENTS

Their findings are published in a paper in the British Journal of Cancer.Postmenopausal women who are overweight are at greater risk of developing breast cancer, as large amounts of body fat secrete much higher levels of the hormone oestrogen and the growth factor leptin, which can encourage tumours to grow.
