EPIDEMIOLOGY OF BREAST CANCER IN UKRAINE WITH CONSIDERATION OF THE FACTORS OF THE CHORNOBYL ACCIDENT

Objective. Assessment of the possible impact of the Chornobyl accident on the incidence of breast cancer in the female population of Ukraine as a whole and in some affected groups.
Object of the study. The female population of Ukraine as a whole and in separate groups of victims women participating in the clean-up works in 19861987, evacuaees from the exclusion zone and inhabitants of the territories most contaminated with radionuclides.
Methods. Statistical, mathematical, cartographic.
Results. This study, covering a significant period of time (19762016), revealed a steady temporal and territorial agglomeration of regions with a higher incidence of breast cancer in the southern and south-eastern regions of Ukraine. Lower in the western and northern regions. There is a steady increase in the incidence rate, but in recent years this growth has slowed down. The epidemiological situation regarding the incidence of breast cancer in the female population of Ukraine during the 30 years after the Chornobyl accident is generally stable. At the same time, a marked increase in the frequency of this pathology in the groups of the affected population, especially in women, participated in clean-up works in 19861987.
Conclusions. A stable agglomeration of regions with high levels of incidence in the south and south-east, and low in the west and north of the country is determined. The dynamics of breast cancer in Ukraine as a whole is characterized by steady growth, although in recent years its pace has slightly decreased. Among the individual population groups affected by the Chornobyl catastrophe (female liquidators, evacuated women from the exclusion zone, residents of the most contaminated with radionuclides territories) only among female liquidators of 19861987 the significant increase was observed in the incidence of breast cancer, which exceeds the national indicators at 1.31.6 times.
Key words: breast cancer incidence, inhabitants of the territories most contaminated by radionuclides, female liquidators, evacuees, age-specific incidence rate, standardized incidence rate, standardized incidence ratio.
