According to the Ministry of Health in Ukraine 26% of the female population for 2018 was overweight or obese. There is a strong biologic basis for an association of obesity with poor breast cancer outcomes. Obesity - a chronic metabolic character, which is the result of the interaction of the endogenous factors, environmental conditions and lifestyle. Endogenous factors could be considered a violation of the genetic and hormonal balance. The external conditions include irregular rhythm nutrition, use of substandard products. By disorders include sedentary lifestyles. Obesity is the first risk factor for metabolic syndrome, diabetes type II, cardiovascular diseases and some forms of cancer, including breast cancer. Since overweight is a risk factor for breast cancer, there is a reason to believe that among patients with breast cancer the percentage of obese women is higher than in the population. The risk of breast cancer in postmenopausal women by 30% more than in premenopausal women with obesity - 50% Furthermore it was proven that obesity is associated with poor prognosis in patients with breast can-cer, regardless of menopausal status.
