According to the results of the analysis, an increase in the relative indicators of the primary incidence of breast cancer in the region by 25%, in the Russian Federation – by 17%. At the same time, the upward trend in indicators is more pronounced in the region: the average growth rate is +2.2% against +1.8% in Russia. In 2021, the region recorded an excess of the all-Russian primary incidence of breast cancer by 9% and in all age groups by 1.1–1.3 times, except for women 75–79 and over 85 years old. During the study period, mortality from breast cancer in the Irkutsk region changed little, while in the Russian Federation there is a downward trend with an average annual rate of 1.5%.
