Question about Gastrin Secretion after NET Removal

There are a few reasons why you could still be overproducing gastrin. It's possible that there's a tiny bit of tumor still left or that some has grown back. That's not very common for stomach NETs but your docs might want to look into it. That's not the only reason this might be happening though, so I would definitely ask your doctor about it the next time you have an appointment with them!
