The risk of developing malignant neoplasms (MN) is associated with old age, but the increase in incidence among young people is becoming a pressing issue. Objective. Analysis of cancer incidence among the young population of cities — administrative centers of the constituent entities of the Siberian Federal District (SFD) for the period 2004—2023. Material and methods. Data from Form No. 7 “Information on Malignant Neoplasms” on the number and age-sex composition of the population of the administrative centers of the Siberian Federal District of Rosstat for 2004—2023 were used. Results. The leading localization in the structure of malignant neoplasms incidence in the administrative centers of the SFD among the male population aged 20—44 years is the lymphatic and hematopoietic tissue (16.2%), among the female population — the mammary gland (29.3%). Dynamic analysis revealed an increase in age-standardized incidence rates (ASR, per 100.000) for the following cancers: breast (from 23.1 to 34.5), colorectal (men: from 3.9 to 5.6; women: from 4.1 to 5.9), skin (men: from 3.5 to 5.3; women: from 4.3 to 7.5), corpus uteri (from 3.4 to 4.5), and thyroid (men: from 2.1 to 3.8; women: from 10.1 to 14.7). For men, a decrease in incidence was observed for stomach cancer (from 4.4 to 2.5 per 100.000) and lung cancer (from 4.9 to 3.4 per 100.000). The incidence of malignant neoplasms among young women was 2.1 times higher than among men. The highest rates were recorded in Barnaul (168.1 and 74.1 per 100.000) and Irkutsk (132.9 and 75.9 per 100.000). Conclusion. Standardized incidence rates of malignant neoplasms in the young population in the administrative centers of the SFD (60.6 in men and 124.6 0/0000 in women in 2019—2023) are higher than the district average (57.0 and 120.6 0/0000), and over 10 years have significantly increased by 12.4% in men and 24.7% in women, outpacing the growth rate of incidence among urban residents of all ages.
