What is metastatic pancreatic cancer?

When cancer spreads from the site from which it originated in the pancreas to involve another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if cancer of the pancreas spreads to the liver, the cancer cells in the liver are pancreatic cancer cells. The disease is then called metastatic pancreatic cancer, not liver cancer. It is treated as pancreatic cancer, not liver cancer.
