Sterling silver contains 92.5% silver. The rest is copper or some other metal. It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time.
There are three types of pancreatic tumors. Insulinoma: This is a rare type of pancreatic tumor that secretes insulin, which lowers the levels of sugar in the blood. Research indicates that only 10% of insulinomas are cancerous. Surgery is the only option for survival of insulinoma and 90% success rate is assured.
Within this category, the vast majority of tumors are adenocarcinomas. Adenocarcinoma is the most common type of pancreatic cancer and accounts for approximately 90% of all pancreatic cancers. Pancreatic neuroendocrine tumors (also called endocrine or islet cell tumors) account for less than 5% of all pancreatic tumors. These tumors tend to grow slower and are less aggressive than exocrine tumors. To learn about other types of pancreatic tumors, contact the Pancreatic Cancer Action Network at 877.272.6226.
