Cancer rectum

Cancer rectum is a form of cancer that occurs in the rectum, which is the lower end of the large intestine. The rectum is the last part of the digestive system, where stool is stored before it is passed out of the body. Cancer rectum is often caused by an abnormal growth of cells in the rectal wall. These abnormal cells can grow and spread to other parts of the body. Symptoms of cancer rectum include rectal bleeding, abdominal pain, and changes in bowel movements. Other symptoms include constipation, feeling full quickly after eating, and unintentional weight loss. Treatment of cancer rectum depends on the stage and type of cancer. It may involve radiation therapy, chemotherapy, or surgery.
