INTRODUCTION AND OBJECTIVE: Colorectal cancer is the fourth prevalent cancer in the world and there are several factors effective on development of the disease. These factors vary based on geographical distribution. The present study is aimed at surveying epidemiology of colorectal cancer and its risk factors in Kermanshah-Iran between 2009 and 2014.

METHODOLOGY: A descriptive cross-sectional study was carried out on all colorectal cancer cases in two Kermanshah-based hospitals Imam Reza and Taleghani between 2009 and 2014. Demographic and epidemiological information was collected from the medical files and interviewing the patients. The collected data was analyzed in SPSS.
