Purpose: This study aimed to project cancer incidence and mortality for 2025 to estimate Korea’s current cancer burden. Materials and Methods: Cancer incidence data from 1999 to 2022 were obtained from the Korea National Cancer Incidence Database, while cancer mortality data from 1993 to 2023 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 2025. A joinpoint regression model was applied to identify significant changes in trends, using only the most recent trend data for predictions. Results: A total of 304,754 new cancer cases and 84,019 cancer deaths are expected in Korea in 2025. The most commonly diagnosed cancer is projected to be thyroid cancer, followed by the colorectal, lung, breast, prostate and stomach cancers. These six cancers are expected to account for 63.8% of the total cancer burden. Lung cancer is expected to be the leading cause of cancer-related deaths, followed by liver, colorectal, pancreatic, stomach, and gallbladder cancers, together comprising 66.6% of total cancer deaths. Conclusion The increasing incidence of female breast cancer and the rise in prostate and pancreatic cancers are expected to continue. As aging accelerates, cancer commonly found in older adults are projected to rise significantly.

Purpose: The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2022, with international comparisons. Materials and Methods: Cancer incidence, survival, and prevalence rates were calculated using the Korea National Cancer Incidence Database (1999-2022), with survival follow-up until December 31, 2023. Mortality data obtained from Statistics Korea, while international comparisons were based on GLOBOCAN data. Results: In 2022, 282,047 newly diagnosed cancer cases (age-standardized rate [ASR], 287.0 per 100,000) and 83,378 deaths from cancer (ASR, 65.7 per 100,000) were reported. The proportion of localized-stage cancers increased from 45.6% in 2005 to 50.9% in 2022. Stomach, colorectal, and breast cancer showed increased localized-stage diagnoses by 18.1, 18.5, and 9.9 percentage points, respectively. Compared to 2001-2005, the 5-year relative survival (2018-2022) increased by 20.4 percentage points for stomach cancer, 7.6 for colorectal cancer, and 5.6 for breast cancer. Korea had the lowest cancer mortality among countries with similar incidence rates and the lowest mortality-to-incidence (M/I) ratios for these cancers. The 5-year relative survival (2018-2022) was 72.9%, contributing to over 2.59 million prevalent cases in 2022. Conclusion Since the launch of the National Cancer Screening Program in 2002, early detection has improved, increasing the diagnosis of localized-stage cancers and survival rates. Korea recorded the lowest M/I ratio among major comparison countries, demonstrating the effectiveness of its National Cancer Control Program.

The cause and manner of death in the Busan and Gyeongnam regions were analyzed using autopsy data performed by the National Forensic Service Busan Institute (NFS BI) for 10 years—from 2014 to 2023. In addition, changes in the number of autopsy cases of elderly individuals aged 65 and older, were analyzed in the Busan and Gyeongnam regions. A total of 6,374 cases were classified, excluding autopsies from the Ulsan area and the Coast Guard, from the NFS BI data. Analysis of the manner of death revealed that 3,203 cases (50.3%) were unnatural deaths; 2,031 cases (31.9%) were natural deaths; and 1,140 cases (17.9%) were deaths of unknown cause. Among the unnatural deaths, accidents were the most common at 1,149 cases (18.0%), followed by suicide at 979 cases (15.4%); and homicide at 583 cases (9.1%). Among natural deaths, heart disease was the most common with 764 cases (37.6%), followed by vascular disease with 351 cases (17.3%). The proportion of the population aged 65 or older in Busan and Gyeongnam has been steadily increasing from 13.7% in 2014 to 21.6% in 2023. Accordingly, the number of autopsies on people aged 65 or older has increased from 72 in 2014 to 174 in 2023, and the number of autopsies on people aged 65 or older accounted for one-quarter of the total number of forensic autopsies commissioned by Busan/Gyeongnam, and performed by NFS BI in 2023. Therefore, we plan to introduce emerging issues relating to population aging and geriatric forensic medicine.
