Colorectal Cancer: Causes, Symptoms, and Treatment

02 September, 2020 Gehna Kapoor

Colorectal cancer is cancer that begins in the colon (present in the large intestine) or rectum. The rectum is located at the end of the colon and connects the colon to the outside of the body. These two parts are the last site of the process of digestion. Cancer begins in from the inner lining of the rectum or colon. This cancer can spread to the muscles, the lymph nodes, and eventually other parts of the body. The extent to which cancer has spread determines the stage of cancer. Colon cancer usually affects older ages but it can happen at any age. Colorectal cancer begins from non-cancerous cells called polyps that can eventually become cancerous. If the polyps are removed before they become cancerous, it can help prevent cancer. In light of the above, the current article intends to discuss the causes, symptoms, and treatment for colorectal cancer.

  2. Blood tests: There are no blood tests to determine if a person has colorectal cancer. However, the doctor may conduct blood tests to know about the overall wellbeing of other parts like the liver and kidney so that they can eliminate the possibility of other diseases.
