Neuroendocrine tumors (NETs) are a rare form of cancer that can occur in any age group, although they are most prevalent in adults. It is estimated that between 3 and 6 out of every 100,000 people in the United States are diagnosed with NETs each year. The average age of diagnosis is between 40 and 60 years old, although NETs have been diagnosed in children as young as three years old and in adults up to the age of 90.
NETs can occur in any part of the body where there are neuroendocrine cells, such as the lungs, pancreas, gastrointestinal tract, and reproductive organs. The most common form of NET is a carcinoid tumor, which is a slow-growing tumor that typically originates in the gastrointestinal tract. Other types of NETs include pheochromocytomas and paragangliomas, which are tumors that typically originate in the adrenal glands, and medullary thyroid carcinoma, which is a tumor that typically originates in the thyroid.
In general, the age of diagnosis for neuroendocrine tumors depends on the type of NET and the location of the tumor. As mentioned above, the average age of diagnosis is between 40 and 60 years old, although NETs can be diagnosed in any age group. It is important to note that early detection is key in the successful treatment of NETs, so it is important to be aware of any symptoms that could indicate the presence of a NET and seek medical attention as soon as possible.
