[3] [4] The disease is divided into stages, from early (stage I) to late (stage IV). [12] Screening the general population has not been found to be effective. [13]
Pancreatic endocrine tumors are named after the type of hormone they release. For example, an insulin-secreting tumor is referred to as an "insulinoma".

To confirm the diagnosis of gastrinoma a series of blood tests must be made. One of those tests is the serum gastrin level, which is the most reliable test for patients with gastrinoma. The normal levels of gastrin are 150 pg/mL ( > 72.15 pmol/L); therefore elevated levels of > 1000 pg/mL (> 480 pmol/L) would establish the diagnosis of ...
An Australian study of 10.9 million people reported that the increased incidence of cancer after CT scan exposure in this cohort was mostly due to irradiation. In this group, one in every 1,800 CT scans was followed by an excess cancer. If the lifetime risk of developing cancer is 40% then the absolute risk rises to 40.05% after a CT.
