What is Adenocarcinoma of the Small Intestine?Adenocarcinoma of the small intestine is a common type of small intestine cancer that originates from the glandular cells that make up the inner wall of the intestine. The tumor can arise from any part of the small intestine. The small intestine lies between the stomach and the large intestine named as colon. It helps to further digest the food that comes from the stomach and also helps in the absorption of nutrients such as vitamins, minerals, carbohydrates, fats, and proteins from food back into the blood.
Disease CausesThere is no well-known cause; however, certain hereditary and genetic mutations, along with certain risk factors such as physical inactivity, cigarette smoking, low-fiber dietary intake, female gender, increasing age, and gluten allergy, are factors that contribute to the development of the small intestine adenocarcinoma.
