Ampullary adenocarcinoma is a rare cancer that starts in the gland cells of the ampulla of Vater-the spot where the bile duct and pancreatic duct join the small intestine. These cells often form a benign adenoma first, which can transform into a malignant carcinoma if not detected early.
Early signs may be mild or easily mistaken for other conditions. As the tumor grows, you may experience:
The precise cause of ampullary adenocarcinoma is often unclear, but several factors can raise your risk:

An adenoma is a non-cancerous tumor that may turn into cancer over time.
On its own, an adenoma is benign and not cancerous. However, it can transform into adenocarcinoma, a malignant cancer arising from gland cells.
An adenoma is a benign (non-cancerous) growth, whereas a carcinoma is a malignant (cancerous) tumor that can invade nearby tissue and spread to other parts of the body.
Diagnosis typically involves endoscopy to visualize the ampulla, tissue biopsy to confirm cancer cells, imaging studies such as CT or MRI scans to assess tumor extent, and blood work to evaluate liver function and tumor markers.
Stage 3 means the tumor has grown more deeply into surrounding tissues or has spread to nearby lymph nodes, but not to distant organs.
Treatment may include surgical removal of the tumor (such as the Whipple procedure), endoscopic ampullectomy for smaller lesions, chemotherapy or radiation therapy to destroy cancer cells, targeted drug therapies for specific tumor profiles, and supportive care for nutrition and pain management.

No. Ampullary adenocarcinoma is rare, affecting roughly 6 people per million each year.
Survival depends on how early the cancer is detected, the stage at diagnosis, and the patient's overall health. Five-year survival rates typically range from about 30% to 50%.
If you experience symptoms like jaundice, upper abdominal pain, sudden weight loss, or changes in stool or urine color, seek specialist evaluation promptly. Early diagnosis and treatment can significantly improve outcomes.
