Pancreatic neuroendocrine tumors (NETs) are rare. Less than 2% of all cancers found in the pancreas each year are pancreatic NETs.
The number of pancreatic NETs diagnosed each year has been rising over time. This is thought to be partly because they are being found more often incidentally, when imaging tests such as CT or MRI scans of the abdomen are done for other reasons. The ability to distinguish these tumors from other types of cancers in the lab has also improved, leading to more of them being diagnosed.
Most people with pancreatic NETs are older, with the average age of diagnosis being 60. These tumors are slightly more common in men than women.
