Pancreatic carcinoma is cancer of the pancreas. Pancreatic cancer is a malignant neoplasm originating from transformed cells arising in tissues forming the pancreas.
The most common type of pancreatic cancer, accounting for 95% of these tumors, is adenocarcinoma (tumors exhibiting glandular architecture on light microscopy) arising within the exocrine component of the pancreas. A minority arise from islet cells, and are classified as neuroendocrine tumors.
