特許 係属中 Pancreatic cancer is a disease caused by cells in the pancreas - a glandular organ located behind the stomach - multiplying out of control. Signs and symptoms of the most common form of pancreatic cancer may include abdominal or back pain, yellow skin, unexplained weight loss, light colored stools, dark urine and loss of appetite. However, there are usually no symptoms in the disease's early stages,[1] and symptoms that are specific enough to suspect pancreatic cancer typically do not appear until the disease is already in an advanced stage.
