Purpose: The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2019.

Materials And Methods: Incidence, survival, and prevalence rates of cancer were calculated using the Korea National Cancer Incidence Database, from 1999 to 2019, with survival follow-up until December 31, 2020. Deaths from cancer were assessed using causes-of-death data obtained from Statistics Korea.

Prediction of Cancer Incidence and Mortality in Korea, 2022.

Purpose: This study aimed to report the projected cancer incidence and mortality for the year 2022 to estimate Korea's current cancer burden.

Materials And Methods: Cancer incidence data from 1999 to 2019 were obtained from the Korea National Cancer Incidence Database, and cancer mortality data from 1993 to 2020 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against their respective years and then by multiplying the projected age-specific rates by the anticipated age-specific population for 2022.

Incidence and mortality projections for major cancers among Korean men until 2034, with a focus on prostate cancer.

Purpose: The Korean population is rapidly aging, and the cancer burden is expected to change significantly. This study aimed to generate projections of incidence and mortality of major cancers among men in Korea until 2034, with a special focus on prostate cancer.
