Neuroendocrine Tumors

Neuroendocrine tumors are a rare group of tumors that can develop in many different organs of the body. They originate from neuroendocrine cells that secrete hormones into the bloodstream. Since neuroendocrine tumors can produce much higher amounts of hormones than normal, they can cause many different symptoms and complaints. Although these tumors can be benign or malignant (cancer), they are often slow-growing and not very aggressive.
