Neuroendocrine tumors are cancers that begin in specialized cells called neuroendocrine cells. Neuroendocrine cells have similar properties to nerve cells and hormone-producing cells.
Neuroendocrine tumors are rare and can occur anywhere in the body. Most neuroendocrine tumors occur in the lungs, appendix, small intestine, rectum, and pancreas.
There are many types of neuroendocrine tumors. Some grow slowly and some grow very quickly. Some neuroendocrine tumors produce excess hormones (functional neuroendocrine tumors). Others don’t release hormones or don’t release enough hormones to cause symptoms (dysfunctional neuroendocrine tumors). Neuroendocrine tumors Treatment in Hyderabad
euroendocrine tumors do not always cause signs and symptoms early. The symptoms that you may experience depend on the location of your tumor and whether excess hormones are being produced.
In general, the signs and symptoms of a neuroendocrine tumor can include:
- Pain from a growing tumor
- A growing lump that you can feel under the skin
- I feel unusually tired
- Lose weight without trying
The exact cause of neuroendocrine tumors is not known. These cancers start in neuroendocrine cells, which have properties similar to nerve cells and hormone-producing cells. Neuroendocrine cells are found throughout the body.
Neuroendocrine tumors start when neuroendocrine cells develop changes (mutations) in their DNA. The DNA in a cell contains the instructions that tell the cell what to do. The changes cause neuroendocrine cells to multiply quickly and form a tumor.
Some neuroendocrine tumors grow very slowly. Others are aggressive cancers that invade and destroy normal body tissue or spread (metastasize) to other parts of the body. Neuroendocrine tumors Treatment in Hyderabad
The risk of neuroendocrine tumors is higher in people who inherit genetic syndromes that increase the risk of cancer. Examples include:
- Multiple endocrine neoplasia, type 1 (MEN 1)
- Multiple endocrine neoplasia, type 2 (MEN 2)
- Von Hippel Lindau disease
- Tuberous sclerosis
