Types of neuroendocrine tumors

While all types of neuroendocrine tumors (NETs) share basic similarities — they start in the same family of cells — their characteristics vary. These uncommon tumors can develop anywhere in the body, but can be found most often in the pancreas, bowel, lungs or adrenal glands.

Some types of neuroendocrine tumors release hormones (functioning tumors) and some don’t (nonfunctioning tumors). Some remain benign (noncancerous), while others turn malignant (cancerous). And while they’re typically slow-growing, even when they metastasize (spread), there are exceptions. Every case is unique — perhaps more so than other tumors.

Experience with the full range of neuroendocrine tumor types

While NETs remain uncommon — about 12,000 new cases annually and around 170,000 people living with the disease — diagnoses have been rising. In part, the trend comes from the increase in detailed scans given for other medical reasons. It’s also tied to the emergence of genetic testing for tumors that run in families. But we may not know all the reasons yet.

At Penn Medicine, we’re prepared to help, regardless of the circumstances. We provide the individualized care required when treating all types of NETs. We know the peculiarities of these tumors and the unique challenges they can pose. We have years of experience with a full variety of neuroendocrine tumor types, including the most unusual and complex:

Rated “exceptional” by The National Cancer Institute

Penn Medicine’s Abramson Cancer Center is a world leader in cancer research, patient care, and education. Our status as a national leader in cancer care is reflected in our continuous designation as a Comprehensive Cancer Center by the National Cancer Institute (NCI) since 1973, one of 7 such centers in the United States. The ACC is also a member of the National Comprehensive Cancer Network, one of a select few cancer centers in the U.S., that are working to promote equitable access to high-quality, advanced cancer care.
