Characteristics of breast cancer incidence trend models in ukraine after the chernobyl accident

Resume. Research of breast cancer dynamics has been carried out for the purpose of revealing its features for the population of both Ukraine in whole and the contaminated after the Chernobyl accident territories. Incidence rates are calculated on the National Cancer Registry personificated database with the use of methods of descriptive epidemiology, mathematical and medical statistics. The research involved 200 thousand of breast cancer cases of 1986-2009 and incidence statistics of 1976-1986. It was ascertained that breast cancer incidence in Ukrainian population keeps stable increasing tendency, with higher increment rate in population of contaminated oblasts. In 1986–2009 incidence increment rates in all these oblasts exceeded average Ukrainian ones. The highest levels of incidence increment rate during 1986-1996 where observed in Zhytomyrska, Rivnenska and Vinnytska oblasts, and in other contaminated oblasts these rates were less intensive at the same time being higher then average Ukrainian level. The results of this research give scientifically grounded priorities for anti-cancer activity in Ukraine considering social, economic and gender peculiarities of population.
