What is Small Intestine Cancer?

Small intestine cancer, also known as small bowel cancer, is a rare type of cancer that develops in the tissues of the small intestine. The small intestine plays a crucial role in digestion and nutrient absorption, and cancer in this area can impact overall health.

Types of Small Intestine Cancer

Adenocarcinoma – The most common type, often starting in the lining of the small intestine.
Neuroendocrine Tumors (Carcinoid Tumors) – Slow-growing tumors that affect hormone-producing cells.
Lymphoma – A cancer that originates in the lymphatic system of the small intestine.
Sarcoma (Gastrointestinal Stromal Tumors - GISTs) – Affects connective tissues and muscle layers of the small bowel.

Symptoms to Watch For

Abdominal pain or cramps
Unexplained weight loss
Blood in the stool or black, tarry stools
Nausea, vomiting, or persistent bloating
Loss of appetite
Fatigue and weakness

Risk Factors

Genetic conditions (Lynch Syndrome, FAP)
Crohn’s disease or celiac disease
Smoking and alcohol consumption
High-fat diet and obesity
Family history of gastrointestinal cancers

Diagnosis & Screening

Endoscopy & Biopsy – A small camera is used to examine the intestine and collect tissue samples.
Imaging Tests (CT, MRI, PET Scans) – Helps detect tumors and determine cancer spread.
Blood Tests & Tumor Markers – To check for abnormalities and cancer indicators.

Treatment Options

Surgery – Removing the tumor or affected part of the intestine.
Chemotherapy – Kills cancer cells or slows their growth.
Radiation Therapy – Targets and destroys cancerous tissues.
Targeted Therapy & Immunotherapy – Advanced treatments to attack cancer at a molecular level.

Why Early Detection Matters
