Pancreatic cancer refers to a malignant neoplasm of the pancreas. The most common type of pancreatic cancer, accounting for 95% of these tumors is adenocarcinoma, which arises within the exocrine component of the pancreas. A minority arises from the islet cells and is classified as a neuroendocrine tumor. 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 death across the globe. Pancreatic cancer often has a poor prognosis: for all stages combined, the 1- and 5-year relative survival rates are 25% and 6%, respectively; for local disease the 5-year survival is approximately 20%[2][3] while the median survival for locally advanced and for metastatic disease, which collectively represent over 80% of individuals, is about 10 and 6 months respectively.
About Kind and Causes Pancreatic Cancer, In the U.S., pancreatic cancer is the fourth leading cause of cancer deaths. About 44,030 people will be diagnosed with it and about 37,660 people will die of it this year in the U.S., the American Cancer Society estimates. But pancreatic cancer has actually been on the decline despite no big advances in treatment or early detection. A decline in smoking - one of the top risk factors for the disease - may explain the drop in cases.
