Colorectal Cancer

Colorectal cancer is a malignancy that develops in the lining of the colon and rectum, the terminal portion of the large intestine. Most of the times, the cancer begins in the colorectal cells of polyps locate in the lining of the large intestine; over time, however, the tumor can extend into the peritoneum and lymph nodes. In this case, the treatment becomes more difficult, and the survival chance decreases considerably. 

The main role of the colon is to ensure the absorption of water and nutrients from undigested food coming from the stomach. The rectum, the terminal segment of the digestive tract, is responsible for the storage of feces (faeces) awaiting defecation. You have colorectal cancer when certain normal cells of the large intestine multiply abnormally to form malignant growth called glandular carcinoma or adenocarcinoma.
