The most common form of breast cancer, hormone-dependent breast cancer, is most likely associated with obesity, especially in postmenopausal women. 40 percent of diseases can be traced back to this.
Naiara Cubelos-Fernandez from the Institute of Biomedicine at the University of Leon in Spain and her co-authors from numerous other Spanish research institutions recently published their research in the Journal of Epidemiology & Community Health.
A long-term study in more than a dozen Spanish provinces examined how body weight and body fat percentage are linked to breast cancer (breast cancer). For this purpose, data on weight, fat percentage and questionnaire information on social situation, marital status and lifestyle, such as diet and alcohol consumption, were evaluated.
Finally, the data from 1,033 subjects with breast cancer were compared with the data from 1,143 women without breast cancer. Accordingly, the risk of breast cancer in postmenopausal women increases with each additional pound.
Taking body mass index into account, the calculation showed that the curve flattens at higher levels of obesity (BMI greater than 40), but this is likely an artifact of the calculation.
When changes occur, estrogen production stops
The link between body fat and hormone-dependent breast cancer after menopause is probably mainly due to the following fact: with the change, estrogen production in the ovaries stops. The fat cells remain as a production site for estrogen. More body fat therefore means more estrogen in the body.
In Austria, approximately 5,600 women develop breast cancer every year. About 1,600 patients succumb to such tumors every year.
