| Summary: | Cancer incidence in the administrative centers of Siberia and the Russian Far East was first studied from1998 to 2012 years. Proportion of urban population ranged from 18.5 % in Kemerovo city to 56.0 % in Magadan city. During the study period, the incidence rate in the administrative centers of the region (259.1 ± 0.4 0/0000) was higher than in the whole region (233.0 ± 0.2 0/0000) (p<0.05). The lowest rates were observed in the Yakutsk city (206.8 ± 2.3 0/0000), Abakan city (212.1 ± 2.6 0/0000) and Kyzyl city (231.5 ± 4.2 0/0000), the largest rates were in Yuzhno-Sakhalinsk city (308.6 ± 3.1 0/0000), Irkutsk city (298.2 ± 1.6 0/0000) and Barnaul city (292.8 ± 1.5 0/0000). A significant rise in cancer incidence was observed among the urban population. The highest growth rates were noted in Irkutsk city (30.1 %), Petropavlovsk-Kamchatsky city (26.8 %), whereas the lowest rates were found in Kemerovo city (0.1 %) and Omsk city (0.3 %). Cluster analysis allowed the group of cities with low and high cancer risk to be identified.
