Question: are all masses on the pancreas cancer?
Answer: A wide spectrum of benign and malignant diseases can produce a mass in the head of the pancreas. It can be solid (ductal adenocarcinoma, chronic pancreatitis, endocrine tumor) or a cystic lesion (cystic neoplasm, true cyst or pseudocyst). The most important question is whether or not it is a malignant or benign tumor.
