Colorectal cancer is a type of cancer that starts in the colon or rectum, which are parts of the digestive system. It typically begins as polyps, which are small growths on the lining of the colon or rectum, some of which can become cancerous over time.Treatment options depend on the stage of the cancer and may include surgery, chemotherapy, radiation therapy, or targeted therapy. Early-stage cancers may be treated effectively with surgery alone, while more advanced cancers may require a combination of treatments.
