Small
intestinal cancer also known as Small Bowel Cancer refers to the formation of
cancerous tumors in parts of the small intestine. Cancer of the Small Intestine
is rare as compared to other malignant tumor formations of the gastrointestinal
system such as Stomach Cancer and Colorectal Cancer.
If left undetected, these tumors have the potential to metastasize and invade
other neighboring structures.
The cancer of the small
intestine can be divided into three categories based on the location: Duodenal
cancer, Cancer of the jejunum and Cancer of the ileum
Apart from these three main categories of small intestine cancer, there exist several subtypes namely:
Adenocarcinoma, Gastrointestinal stromal tumor, Lymphoma and Ileal carcinoid tumor. Often, non-cancerous tumors and health conditions like the hamartoma and tuberculosis tend to be mistaken for small intestinal cancer.
What are the Risk factors of Small Intestine Cancer?
Several factors may increase the risk of small intestine cancer. In general, it is noticed that the incidence is higher among male than women. Exposure to certain radiations, carcinogenic agents and environmental pollutants may also raise the risk of an individual getting affected by cancer of the small intestine. Also, individuals suffering from Celiac Disease, Crohn’s disease and familial adenomatous polyposis are at a much greater risk. Adenocarcinoma, one of the most deadly malignant cancers, occurs more often in industrialized countries as opposed to the developing countries.

Whereas, the occurrence of
lymphomas are more common in developing countries. Also, exposure over a prolonged
duration of time to some substances such as Alcohol, sugar, salted or smoked meats and fishes can
significantly increase the risk of different types of small intestinal cancers.

How can we
Diagnose Small Intestine Cancer?
An endoscopy of the upper gastrointestinal tract can help detect cancerous formations in the region. A barium contrast study of the small intestine, also known as the small bowel series, may also help in the diagnosis. Other diagnostic tools include an abdominal ultrasound, a CT scan of the abdomen and a Colonoscopy.

How can Small
Intestine Cancer be Treated?
Surgical removal of the tumor is the primary treatment. In case the tumor has metastasized and is not localized to one area then Chemotherapy may be helpful. On the other hand, radiation therapy may help destroy cancerous tumors localized to a particular area.
