Patients with an<unk>  initially exhibit symptoms of hypoglycemia resulting from excess insulin secretion from the islet beta cells within the pancreatic tumor or from non-pancreatic tumor cells. The excess insulin secretes into the blood stream and causes a significant drop in the blood glucose level, also known as hypoglycemia. Hypoglycemia is accompanied by many of the above listed neuroglycopenic and/or autonomic symptoms. In<unk> , cancerous cells from the initial<unk>  begin to break away and enter into either the bloodstream or the lymphatic system. Upon spreading and entering another part of the body, the process of metastasis has successfully occurred. The cancerous cells can now more rapidly divide and further spread. The main sites of metastasis for pancreatic cancer are the: liver, lung and peritoneum.
