Cancer of the Small Intestine
What is Cancer of the Small Intestine?
The small intestine is a long tube that folds many times to fit inside the abdomen. It connects the stomach to the large intestine (the bowel), and breaks down food to remove vitamins, minerals, proteins, carbohydrates, and fats.
Cancer occurs as the result of abnormal cell growth within the small intestine. There are four types of cancer of the small intestine, depending upon the type of cancer cells found.
Types of Cancers in the Small Intestines
Adenocarcinoma: Most common type; begins in the lining of the small intestine, usually near the stomach.
Lymphoma: Usually non-Hodgkin’s lymphoma; begins in the lymph tissue in the small intestine.
Leiomyoarcoma: Start growing in the smooth muscle lining of the small intestine
