Neuroendocrine tumor: Overview

Neuroendocrine tumors are rare kinds of tumors that can form in many places in the body. They are most often found in the intestines, pancreas, and lungs. There are many kinds of these tumors. Most are cancer (malignant), but some may not be cancer (benign). Their cause is often not known.

Sometimes these tumors release hormones that cause symptoms. Symptoms depend on the type and location of the tumor. They can include flushing, diarrhea, and dizziness. But some people don't have symptoms.

These tumors are diagnosed using imaging tests such as CT scans, MRIs, and ultrasound tests. Blood and urine tests or a sample of tissue (biopsy) are also used.

Treatments include surgery and medicines, such as chemotherapy. Tumors that have spread to the liver can be destroyed in other ways. You may not need treatment right away. In some cases, your doctor may watch your condition.
