What hormones do neuroendocrine tumors secrete?

These include not only blood serotonin and urine 5HIAA but also chromogranin A, Neuron Specific Enolase, Pancreatic Polypeptide, Calcitonin, Substance P, Neurokinin A, Prostaglandin A,E and D, Histamine and Pancreastatin.

How long does it take a carcinoid tumor to grow?

It is microscopic in size and then grows. How long does it take for a carcinoid tumor to grow to the size of 2 cm? In general, it can take 3-5 years and even up to 10 or longer for carcinoid tumors to grow. These are generally very slow-growing tumors.

Can carcinoid tumors cause weight gain?

Some carcinoid tumors produce ACTH (adrenocorticotropic hormone), a substance that causes the adrenal glands to make too much cortisol (a steroid). This can cause Cushing syndrome, with symptoms of: Weight gain.

What foods to avoid if you have carcinoid tumors?

Avoid foods that contain high amounts of mines, nitrogen-containing organic compounds, as they can trigger the release of serotonin and other hormones.
