Pancreatic cancer is a malignant neoplasm of the pancreas. About 95% of exocrine pancreatic cancers are adenocarcinomas.
The remaining 5% include adenosquamous carcinomas, signet ring cell carcinomas, hepatoid carcinomas, colloid carcinomas, undifferentiated carcinomas, and undifferentiated carcinomas with osteoclast-like giant cells. Exocrine pancreatic tumors are far more common than pancreatic endocrine tumors, which make up about 1% of total cases.
Imaging studies, such as computed tomography (CT scan) and endoscopic ultrasound (EUS) can be used to identify the location and form of the cancer.
