. Slender women whose body contains unusual amounts of fat, significantly more likely to suffer from breast cancer than their counterparts with a normal weight of fat, said the physicians speaking at the annual conference of the American Association for the study of cancer.

«These results will likely surprise of doctors and their patients as the body mass index is now used to assess risks associated with obesity and other metabolic problems. We hope that our discovery will make women to think about the fact that fat may contribute to the development of breast cancer even if they have normal BMI,» said Andrew Dannenberg (Dannenberg Andrew) from Cornell University (USA).

In recent years, scientists are finding more hints that obesity not only increases the load on the skeleton, contributes to the development of problems with the metabolism and is one of the causes of diabetes, but also affects other parts of the body. For example, recently scientists from the USA found that overweight women contributed to recurrence of breast cancer and also accelerates aging of the brain and causes changes in the brain.

Dannenberg and his colleagues found that these negative effects are actually more complicated than they seemed in their discoveries, observing the life about 3.5 thousand women in middle-age for about 16 years. During this time approximately two hundred of them were victims of different forms of breast cancer, helping physicians assess how the probability of development is influenced by weight.

The primary analysis of these data revealed a very unexpected thing – was that the likelihood of developing cancer are not dependent on the body mass index, as early scientists believed, and how much fat is present in their body. In other words, women with lower BMI whose body contained abnormally much fat, suffered from cancer more often than their contemporaries of similar mass, but lower proportion of fat in the body.

According to calculations of scientists, the increase in fat mass of approximately 5 pounds increases the probability of development of severe forms of breast cancer by 35%, even in cases when women were not obese and were considered slim. A similar pattern as concludes Dannenberg, physicians must consider in the diagnosis of cancer and the carrying out of regular surveys among women aged.
