Pancreatic cancer refers to 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. The symptoms that lead to diagnosis depend on the location, the size, and the tissue type of the tumor. They may include abdominal pain and jaundice (if the tumor compresses the bile duct). Pancreatic cancer is the fourth most common cause of cancer-related deaths across the globe.
