    This study aimed to assess the epidemiological changes for breast, cervical colon and rectum cancer in Kazakhstan before and during the COVID-19 by using data of Oncological service of the Republic of Kazakhstan for 2017 -2022 period of years.The cohort comprised of patients aged 20 to 49 years -EOC and aged 50 years and olderlate-onset cancer (LOC) from the total number of patients diagnosed each year during the study period from 2017 to 2022 for breast, cervical, сolon and rectum cancer type. In order to indicate a difference in one-time interval and to characterize the global trend over the entire study period Annual percentage change (APC) and average APC (AAPC) were calculated, correspondingly.Results: Breast cancer detection rates increased by 22.8% for EOC and 15.9% for LOC from 2017 to 2022, AAPC increased by 4.3% for EOC and 3.6% for LOC. During the COVID-19 restriction period, breast cancer detection rates decreased by 6.1% for EOC and 15.6% for LOC. Cervical cancer detection rates increased by 2.3% for EOC and 7.5% for LOC from 2017 to 2022, AAPC increased by 0.9% for EOC and 1.6% for LOC. During the COVID-19 restriction period, cervical cancer detection rates decreased by 11.3% for EOC and 3.1% for LOC. Colon cancer detection rates increased by 18.4% for EOC and 14.3% for LOC from 2017 to 2022, AAPC increased by 3.7% for EOC and 2.9% for LOC. During the COVID-19 restriction period, colon cancer detection rates decreased by 14.4% for EOC and 5.8% for LOC. Rectum cancer detection rates increased by 13.6% for EOC and 19.2% for LOC from 2017 to 2022, AAPC increased by 3.0% for EOC and by 3.9% for LOC. During the COVID-19 restriction period, rectum cancer detection rates increased by 18.6% for EOC and decreased by 12.0% for LOC.The epidemiological indicators of population cancer screening have worsened during the COVID pandemic, the detection rate for breast cancer EOC decreased by 6.1%, for cervical cancer EOC decreased by 11.3%, while there was an increase in EOC for colon cancer in men by 38.0%, and rectum cancer in men by 8.0%, and women by 31.1%.
