Neuroendocrine tumors (NETs) are a type of tumor that affects the cells of the neuroendocrine system, which is responsible for regulating hormones and other body functions. NETs can be either cancerous or non-cancerous, and the type of tumor depends on the type of cell affected.
What Are Neuroendocrine Tumors?
Neuroendocrine tumors are growths that form in the neuroendocrine system, which is responsible for regulating hormones and other body functions. The tumors can form in any part of the nervous system, including the brain, spinal cord, and peripheral nerves. Neuroendocrine tumors can be either benign (non-cancerous) or malignant (cancerous), depending on the type of cell affected.
Can Neuroendocrine Tumors Be Non-Cancerous?
Yes, some neuroendocrine tumors can be non-cancerous. Benign neuroendocrine tumors are usually slow-growing and rarely cause any symptoms. They can often be removed surgically, and they do not typically spread to other parts of the body.
What Are the Symptoms of Neuroendocrine Tumors?
The symptoms of neuroendocrine tumors depend on where the tumor is located and what type of cell it affects. Common symptoms include headaches, seizures, balance problems, vision changes, and cognitive changes. In some cases, neuroendocrine tumors can also cause hormonal imbalances, which can cause symptoms such as weight gain, fatigue, and changes in appetite.
How Are Neuroendocrine Tumors Diagnosed?
Neuroendocrine tumors are typically diagnosed through imaging tests such as MRI and CT scans. A biopsy may also be performed to confirm the diagnosis.
How Are Neuroendocrine Tumors Treated?
Treatment for neuroendocrine tumors depends on the type and size of the tumor. Surgery is often the first line of treatment for benign tumors, while chemotherapy and radiation may be used to treat malignant tumors. In some cases, targeted drug therapy may be used to shrink the tumor or slow its growth.
