Purpose: The purpose of this study was to investigate the health care utilization in Korean women with cervical cancer and cervical intraepithelial neoplasia (CIN). Methods: This is a retrospective study. Data were collected using the insurance coverage data-base of Health Insurance Review and Assessment Service (HIRA) from January 1, 2006 to December 31, 2010. Women who were treated for cervical cancer and cervical intraepithelial were included in this study. The data were analyzed using descriptive statistics. Results: In 2006, women treated for cervical cancer and CIN were 27,109 and 18,794, respectively. The number constantly increased from 2006 to 2010. In particular, the prevalence among women with cervical cancer aged 80 years or over was found to increase. Claims for health care services increased. Conclusion: Even though new cases of cervical cancer in Korea is decreasing, the number of women being treated and the costs are constantly increasing. Cervical cancer patients are at an increased risk of negative health outcomes. Therefore, screening for cervical cancer should be enforced to promptly treat women with abnormal Pap tests and thus minimize the risks. Every effort should be made to increase awareness about the importance of Human Papilloma Vaccination and regular screening on a personal as well as community and governmental levels.
