Rectum Cancer: (1) Overview (2) Risk factors (3) Signs & Symptoms (4) Diagnosis as per modern science (5) Staging (1) Overview: - The rectum is part of the body’s digestive system. The digestive system removes and processes nutrients, vitamins, minerals, carbohydrates, fats, proteins, and water from foods and helps pass waste material out of the body. The digestive system is made up of the esophagus, stomach and the small and large intestines. The first 6 feet of the large intestine are called the large bowel or colon. The last 6 inches are the rectum and the anal canal. The anal canal ends at the anus, the opening of the large intestine to the outside of the body. (2) Risk factors: - (i) Age 50 years or above. (ii) A family history of cancer of the colon or rectum (iii) A personal history of cancer of the colon, rectum, ovary, endometrium or breast. (iv) A history of ulcerative colitis (Ulcers in the lining of the large intestine or crohn’s disease.) (v) Certain hereditary conditions such as familial adenomatous polyposis and hereditary non-polyposis colon cancers.
