Key Statistics for Pancreatic Neuroendocrine Tumor

Pancreatic neuroendocrine tumors (NETs) are rare and account for about 7% of all cancers that occur in the pancreas. The American Cancer Society’s estimates predict that about 4,032 people in the United States will be diagnosed with pancreatic NET in 2020.

The occurrence of pancreatic NETs seems to be rising over the years. This is thought to be partly because they are more often found incidentally, when imaging tests such as CT or MRI scans are done for other reasons. Also, the ability to distinguish these tumors from other types of cancers in the lab has improved. 

Most people with pancreatic NETs are older, with the average age of diagnosis being 60. They are slightly more common in men than women.

People with pancreatic NETs that are grade 1 or 2 tend to live longer than those with grade 3 pancreatic NETs. For more statistics related to survival, see Pancreatic Neuroendocrine Tumor Survival Rates by Stage.
