For the presence of cancer in the small intestine may indicate: abdominal pain, constipation, fever and sudden weight loss, etc.

For diagnosing small bowel cancer patients are given barium sulfate for x-rays.

Speaking about the varieties of cancer of the small intestine, we are talking primarily about adenokartsenome small intestine .Chasche all this tumor is localized in the duodenum. Thus, patients are advised to periodically endoscopic examinations of the gastrointestinal tract. Upon detection of any pathology in the area periampulyarnoy polyps and duodenal biopsy should be performed.
Lymphoma.

The risk of developing lymphoma is higher in patients with congenital or acquired immunodeficiency, including AIDS patients, organ transplant, chemotherapy of malignant tumors and patients with systemic vasculitis, connective tissue, nodular lymphoid hyperplasia, cancer, celiac disease, as well as in persons exposed to ionizing radiation. You can diagnose lymphoma by biopsy.

Mediterranean lymphoma – a tumor affecting young people in those parts of the world where common intestinal parasites (the Mediterranean, Asia, South America).
Another type of cancer is leymosarkoma. LMS – is rarely found a malignant tumor that develops from smooth muscle tissue.
Most often develop in the uterus, stomach, small intestine, bladder, skin.
