Colorectal neoplasms are abnormal growths that occur in the colon or rectum. These growths can be benign (non-cancerous) or malignant (cancerous). The most common type of colorectal neoplasm is colorectal cancer, which can develop from polyps, small growths that form on the lining of the colon or rectum. Risk factors for colorectal neoplasms include age, family history, and certain lifestyle choices such as diet and physical activity. Regular screening, such as colonoscopy, is recommended for early detection and prevention, as it can identify polyps before they turn into cancer.
