Malignant neoplasms are more common than benign lesions in the colorectum. Patients above 50 years are affected more commonly, and the maximum incidence of both benign and malignant lesions is seen in the 6th decade. In this study, it was also seen that females were more affected (marginally) as compared to males in the present study. Rectum is the most frequent site of occurrence of neoplasms. Adenocarcinoma is the commonest tumour of colorectum. The prevalence of CRCs in age, site, and histopathological type was comparable to other studies done in India and abroad. The commonest polypoidal lesion is adenomatous polyp followed by hyperplastic polyp.
An increasing incidence of colorectal malignancies has been observed in patients less than 50 years of age. Family history, consumption of alcohol and red meat, obesity, and cigarette smoking are risk factors associated with malignant neoplasms in this area. Thus, any patient having a change in bowel habits, iron deficiency anaemia, abdominal pain, blood or mucus in stool, should be examined (digital rectal examination) and investigated by proctosigmoidoscopy/ colonoscopy and other radiological tests for early diagnosis and management of colorectal carcinoma.
