Pancreatic cancer is a malignant neoplasm originating from transformed cells arising in tissues forming the pancreas. Pancreatic cancer (cancer of the pancreas) mainly occurs in people aged over 60. If it is diagnosed at an early stage, then an operation to remove the cancer gives some chance of a cure. In general, the more advanced the cancer (the more it has grown and spread), the less chance that treatment will be curative. Both the exocrine and endocrine cells of the pancreas can form tumors. But tumors formed by the exocrine cells are much more common. Pancreatic cancer cells do not experience programmatic death, but instead continue to grow and divide.
