Lose 5% body fat may decrease risk of breast cancer by up to 50%

Study indicates that diet decreases the rate of disease-causing hormones 

A new survey, developed by the Department of Epidemiology and Biostatistics, University of California (USA), suggests that losing 5% of body weight through diet and exercise lowers rates hormones estrogen and testosterone, related to breast cancer in blood of women with obesity, reducing risk disease. The study was published online in the Journal of Clinical Oncology.

The findings do not prove that weight loss can prevent breast cancer,

but it is an option for reducing risk without significant side effects. For the study, 439 overweight women were divided into four groups together. One group did exercises (mostly walking), the second group went on a diet, the third did both and the last group did not make any change in routine. The participants were aged between 50 and 75 years, with an average of 58 years.

Those made ​​only diet or diet in conjunction with exercise lost about 10% by weight, and the levels of testosterone and estrogen have decreased between 10 and 20%. According to the researchers, the amount of weight lost was key to changes in hormone levels, but only do physical activity did not produce a large change in weight or hormone levels.

The researchers cautioned that the study does not claim that losing weight decreases the risk of breast cancer, just make a list, because more and more time consuming to prove this study would be necessary. They explain, however, that the weight loss has an effect on circulating estrogen hormones, making it probable that reduces the risk of cancer.
