Expert Care for Small Intestine Cancer

Small intestine cancer, also known as small bowel cancer, develops when abnormal cells grow uncontrollably in the tissue lining the small intestine — the long, coiled organ that connects the stomach to the large intestine and plays a key role in digesting food and absorbing nutrients. It is a rare form of gastrointestinal cancer, accounting for only a small percentage of all digestive system cancers.

At AIROC Hospitals, our gastrointestinal oncology specialists provide expert, comprehensive care for small intestine cancer, using advanced diagnostic tools and a multidisciplinary approach to ensure accurate diagnosis and effective, personalized treatment.

Because the small intestine is long, flexible, and located deep within the abdomen, cancers here can be difficult to detect in their early stages and often present with vague or nonspecific symptoms. This makes timely evaluation by experienced specialists essential for early diagnosis and better treatment outcomes.

At AIROC Hospitals, we are dedicated to guiding patients through every stage of their small intestine cancer journey with advanced expertise, cutting-edge technology, and compassionate, patient-centered care.

Types

Small intestine cancer is classified based on the type of cell in which it originates. The main types include:

• Adenocarcinoma – The most common type of small intestine cancer, developing in the glandular cells lining the intestinal wall, most often found in the duodenum (the first section of the small intestine).
• Carcinoid Tumors (Neuroendocrine Tumors) – Slow-growing tumors that arise from hormone-producing cells, most commonly found in the ileum (the final section of the small intestine).
• Gastrointestinal Stromal Tumors (GISTs) – Tumors that develop in specialized cells found in the wall of the small intestine, ranging from slow-growing to aggressive.
• Lymphoma – A cancer of the immune system cells that can develop in the lymphatic tissue of the small intestine.
• Sarcoma – A rare cancer that originates in the muscle, fat, or connective tissue layers of the intestinal wall.

Small intestine cancer is further categorized by stage (0 through IV), based on tumor size, depth of invasion, and whether it has spread to lymph nodes or distant organs — important factors in determining the treatment approach at AIROC Hospitals.

Symptoms and Causes

Symptoms

Small intestine cancer often causes few or no symptoms in its early stages, and signs can be subtle or easily mistaken for other digestive conditions. As the disease progresses, symptoms may include:

• Abdominal pain or cramping
• Unexplained weight loss
• Nausea and vomiting
• A noticeable lump in the abdomen
• Blood in the stool or dark, tarry stools
• Diarrhea
• Yellowing of the skin and eyes (jaundice), if the tumor affects nearby bile ducts
• Weakness or fatigue due to anemia

Because these symptoms overlap with many common digestive disorders, prompt evaluation at AIROC Hospitals is important for timely and accurate diagnosis.

Causes and Risk Factors

The exact cause of small intestine cancer is not always clear, but it develops when genetic mutations lead to abnormal, uncontrolled cell growth. Known risk factors include:

• Age – Risk increases with advancing age, typically occurring in individuals over 60.
• Inherited Genetic Syndromes – Conditions such as Lynch syndrome, familial adenomatous polyposis (FAP), and Peutz-Jeghers syndrome significantly increase risk.
• Crohn's Disease – Chronic inflammation of the digestive tract raises the risk of small intestine cancer, particularly in the ileum.
• Celiac Disease – Long-term, untreated celiac disease is associated with a higher risk.
• Diet – Diets high in red or processed meats and low in fruits and vegetables may contribute to increased risk.
• Smoking and Alcohol Use – Both are linked to a higher likelihood of developing small intestine cancer.
• Family History – A family history of colorectal or small intestine cancer can increase individual risk.

Diagnosis and Treatment

Diagnosis

At AIROC Hospitals, our specialists use a comprehensive, step-by-step approach to accurately diagnose small intestine cancer:

• Endoscopy – Allows direct visualization of the upper portion of the small intestine using a thin, flexible camera.
• Capsule Endoscopy – A swallowable capsule camera that captures images throughout the small intestine to identify abnormal areas.
• Double-Balloon Enteroscopy – A specialized procedure that allows deeper examination and biopsy of the small intestine.
• Biopsy – Confirms the presence and type of cancer through microscopic examination of tissue samples.
• CT and MRI Scans – Provide detailed imaging of the small intestine and surrounding structures to assess tumor size and spread.
• PET Scan – Helps detect whether cancer has spread to lymph nodes or distant organs.
• Blood Tests – Including tumor markers and tests to check for anemia or liver function abnormalities.

Treatment

Treatment at AIROC Hospitals is tailored to the cancer's type, stage, and location within the small intestine, as well as the patient's overall health. Options include:

• Surgery – The primary treatment for most small intestine cancers, involving removal of the tumor along with a margin of healthy tissue and, when necessary, nearby lymph nodes.
• Chemotherapy – Used before or after surgery, or as the main treatment for advanced or metastatic disease.
• Radiation Therapy – Used in select cases to shrink tumors or destroy remaining cancer cells after surgery.
• Targeted Therapy – Drugs designed to attack specific genetic or molecular features of the cancer, particularly useful for GISTs.
• Immunotherapy – An emerging treatment option for certain small intestine cancers with specific genetic markers.
• Hormone Therapy (Somatostatin Analogs) – Used for carcinoid tumors to control symptoms and slow tumor growth.

A dedicated multidisciplinary tumor board at AIROC Hospitals — comprising gastrointestinal surgeons, medical oncologists, radiation oncologists, and gastroenterologists — works collaboratively to design the most effective, individualized treatment plan for each patient.

Prevention and Risk Factors

While small intestine cancer cannot always be prevented, certain lifestyle and health measures may help lower risk:

• Manage Underlying Conditions – Proper management of Crohn's disease and celiac disease can help reduce associated risk.
• Eat a Balanced Diet – Emphasize fruits, vegetables, and whole grains while limiting red and processed meats.
• Maintain a Healthy Weight – Supports overall digestive health and reduces cancer risk.
• Avoid Tobacco and Limit Alcohol – Both are associated with increased risk of small intestine cancer.
• Know Your Family History – Individuals with a family history of related genetic syndromes or colorectal cancer should discuss genetic counseling and screening with their doctor.
• Seek Prompt Evaluation of Symptoms – Early attention to persistent digestive symptoms allows for timely diagnosis and better outcomes.

At AIROC Hospitals, we encourage individuals with risk factors or persistent digestive symptoms to seek timely evaluation — early detection remains key to successfully managing small intestine cancer.
