Intestinal cancer, also known as colorectal cancer, is a type of cancer that affects the large intestine (colon) and the rectum. These two organs are part of the digestive system and they help in the absorption of nutrients and the elimination of waste from the body. Intestinal cancer is the third most common type of cancer found in both men and women, and it is the second leading cause of death from cancer in the United States. Intestinal cancer usually starts as polyps, which are small, non-cancerous growths in the lining of the intestine. Over time, these polyps can become cancerous and grow into a tumor. While the exact cause of intestinal cancer is unknown, there are certain risk factors, such as diet, age, family history, and smoking, that can increase an individual’s chances of developing the disease. Early detection of intestinal cancer is key in increasing the chances of successful treatment. Common symptoms of intestinal cancer include abdominal pain, changes in bowel habits, unexplained weight loss, and blood in the stool. If you experience any of these symptoms, it is important to see your doctor right away.
