? If all the women who crossed the red line of obesity could bend their weight curve, 13,000 breast cancers could be avoided each year in Europe.

" Overweight increases estrogen levels in women," says Dr. Brigitte Séradour, president of the French Society of Senology and Breast Pathology. Even past menopause, fat stored in adipose tissue can continue to produce these hormones . However, the longer the woman's exposure to estrogen, the greater the risk of breast cancer . From then on, in his fifties, to maintain himself or to return to a normal weight would divide this risk by two!

"However, says Professor Jean-Marie Bard of the Center for the fight against cancer in Nantes, it is not so much the body mass index that counts, but the distribution of fat. The risk is to take the belly: the ideal is not to exceed 88 cm waist circumference, beyond which it increases its risk of cancer and cardiovascular disease.
