Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine (hormonal) and nervous systems. Many are benign, while some are malignant. They most commonly occur in the intestine, where they are often called carcinoid tumors, but they are also found in the pancreas, lung and the rest of the body.
Neuroendocrine Cancer Symptoms. Pheochromocytoma, or cancer occurring in the adrenaline producing glands, causing excess of adrenaline production, though rare, can be fatal. This is because in any injury, excess adrenaline can significantly increase heart rate and blood pressure.
Summary Carcinoid tumors - NETs that most commonly arise in the digestive tract, lungs, appendix or thymus. They can also grow in the lymph nodes, brain, bone,... Pancreatic neuroendocrine tumors (also called islet cell tumors) - NETs that typically arise in the pancreas, although they can occur ...
Overview. Neuroendocrine tumors are rare and can occur anywhere in the body. Most neuroendocrine tumors occur in the lungs, appendix, small intestine, rectum and pancreas. Neuroendocrine tumors can be noncancerous (benign) or cancerous (malignant). Diagnosis and treatment of neuroendocrine tumors depend on the type of tumor, its location,...
Merkel cell cancer, a type of skin cancer, also is considered a neuroendocrine cancer. NETs are rare, complex and may be difficult to diagnoses. That’s why it’s important to get expert care from a dedicated team with experience and training in treating cancer.
Neuroendocrine tumor refers to the type of cell that a tumor grows from rather than where that tumor is located. Neuroendocrine cells produce hormones or regulatory proteins, and so tumors of these cells usually have symptoms that are related to the specific hormones that they produce.
A neuroendocrine tumor (NET) begins in the specialized cells of the body’s neuroendocrine system. These cells have traits of both hormone-producing endocrine cells and nerve cells. They are found throughout the body’s organs and help control many of the body’s functions.
Depending on the type of NET, a person may experience the following tumor-related symptoms or signs: General cancer symptoms: Fatigue. Loss of appetite. Unexplained weight loss. Symptoms related to the tumor size and/or location: Persistent pain in a specific area. Thickening or a lump in any part of the body. Nausea or vomiting
Neuroendocrine tumors metastatic to the liver. Even in case of metastatic spread to the liver there are some important differences in the nature of these tumors compared to gastrointestinal and pancreatic adenocarcinomas. They typically show 1) specific clinical symptoms and signs and a protracted course, 2) production of hormones and or amines,...
