FORMATION OF GROUP RISK IN BREAST CANCER PATIENTS REGARDING TO DISTINCTIVE MEDICAL AND GENETIC FACTORS IN WOMEN OF ALTAI REGION

Abstract

Epidemiology of breast cancer (BC) is the most studied, not only because of the high incidence of this tumor, but also of the significant aesthetic and social importance of this organ for women [2,5]. The incidence of breast cancer holds a leading place for more than 20 years in the structure of cancer pathology in women in the Russian Federation and in the Altai region [5,8]. There are no trends in decreasing of morbidity: in 2002 in the Russian Federation this parameter was 38.89 per 100 thousand (%ooo, standardized parameter), in 2012 - 46.17%ooo (increase during past 10 years - 19.94%) [5]. There is the same trend in the Altai region: the growth of rough parameter of the incidence of breast cancer in the period 2004-2012 was 28.2%, the standardized parameter - 46.76%ooo in 2012 [5]. Breast cancer - one of the 3 malignant neoplasms (MN) which is designed for mammography screening, which significantly reduces the mortality from this MN in women aged 50-69 years [2,7,9,15]. Today, multiple risk factors are studied and identified enabling the development of oncological risk group, which aims is the prevention and early diagnosis of breast cancer [1,3,6,12,19,23]. It is proved that up to 10% of malignant breast tumors are genetically determined and, perhaps, the most of molecular genetic studies in oncology are focused on breast cancer problems [10,13,14,16,17,24]. At the same time, despite the many advances in the prevention and diagnosis of this disease, the high levels of mortality are stably maintained. Mortality from breast cancer in the Altai region in 2013 was 28.1%ooo (in the Russian Federation in 2012 - 29.8%ooo) [5]. Thus, the problem of prevention of malignant tumors of the breast is not yet resolved and remains extremely relevant.
