They are sensitive ...Read more

What are carcinoid tumors / syndrome?

Neuroendocrine tumor: It is a relatively benign type of tumor that can secrete a variety of hormones, most notably serotonin. They are most commonly found in the gut or the lungs. They do not come from the lining of the lungs or the gut (as adenocarcinomata do). They come from a different line of cells. Carcinoid syndrome occurs when large amounts of serotonin get into the bloodstream, assoc with flushing and diarrhea. ...Read more

In everyday usage, we use "tumor" ...Read more
