Epidemiological Patterns of Common Cancers in Costa Rica: An Overview up to 2020

INTRODUCTION: The increasing cancer incidence and mortality rates in Costa Rica have become a public health concern, with prostate, breast, and colorectal cancers being the most prevalent. This study aimed to analyze the trends in cancer incidence and mortality rates by tumor type, sex, age group, and geographic region using data from the Costa Rican National Cancer Registry. METHODS: In this retrospective study, we analyzed cancer incidence and mortality anonymized data from the Costa Rican National Cancer Registry between 2010 and 2020. The study included data on cancer cases diagnosed and deaths attributable to cancer within the population. RESULTS: Our findings revealed variations in cancer incidence and mortality rates based on geographic region, age group, and tumor type. Cancer was most predominant in the province of San Jose, followed by Alajuela, Heredia, Cartago, Guanacaste, and Puntarenas. Breast cancer, colorectal cancer, and prostate cancer were the leading causes of cancer in both sexes. Mortality rates due to gastric cancer and prostate cancer were highest among men, while breast cancer was the leading cause of cancer mortality among women. CONCLUSION: The results of this study underscore the need for targeted prevention and screening programs, improved access to treatment for patients living in rural areas, and a comprehensive cancer control program in Costa Rica. By implementing evidence-based interventions, such as tobacco control programs, cancer screening initiatives, and equitable access to cancer treatment, the cancer burden in Costa Rica can be mitigated, ultimately improving the overall health of the population.
