Weight loss lowers cancer risk

Even moderate weight loss can significantly reduce levels of circulating oestrogens which are associated with an increased risk of breast cancer, US researchers have found.

Results suggested that losing just five per cent or more of one's weight could cut by a quarter to a half the risk for the most common, oestrogen-sensitive breast cancer said researcher, director of the Prevention Centre at Fred Hutchinson Cancer Research Centre, Dr Anne McTiernan.

The study in 439 overweight to obese sedentary women aged 50 to 75 was the first to show that losing weight through a healthy diet significantly lowered blood oestrogen levels in postmenopausal women and led to average weight losses of 10 percent of their starting weight. The most striking effect was if diet was combined with exercise.

"This shows that it's never too late to make lifestyle changes to reduce your risk for breast cancer," Dr McTiernan said.
