INTRODUCTION: Colon cancer (CC) is seen in both sexes at the third frequency, and it is the cause of cancer-related deaths at the second frequency despite the advances in diagnosis and treatment. This study, it was aimed to evaluate the patients diagnosed with CC and their general demographic features in Bolu. METHODS: CC patients' gender, age, body mass index (BMI), the primary location of the tumor, pathological diagnosis, grade, staging, location of metastasis and treatments administered were recorded retrospectively. RESULTS: Those diagnosed with CC constituted16.54% of all cancer patients during the study period. 199(60.49%) of 329 patients included in the study were male, and 130 (39.51%) were female. The median diagnosis age in men and women was 64 years, the maximal age range of diagnosis was 60-69 years (32.66% and 32.22%, respectively). It was found that 6.53% of men and 26.15% of women were obese. The pathological diagnosis of 317 (96.35%) of the patients was adenocarcinoma, and the highest Grade 2 tumors subsisted (48.63%) (p= 0.696). The most diagnosed stage was stage III in men (36.68%) and stage II in women (38.46%) (p=0.044). While the appeal with the metastatic stage was 25.13% in men, it was seen at 17.69% in women (p=0.044). DISCUSSION AND CONCLUSION: In Bolu, CC is among the cancers in the early stage diagnostic screening program. It is important to increase the training and participation in these programs and to provide healthy nutrition and exercise training to avoid obesity which plays an important role, especially in women, in CC etiology. In addition, prospective studies should be carried out to prevent data loss and to reach healthy statistical results in our country.
