It sounds as if your doctor is following up with the necessary tests, @es2000ca, and that is a good thing. As you probably know, NETs is a very slow-growing cancer. My surgeries were in 2003, 2005 and not again until 2016. So keep a watch out and be sure to follow up, especially if you have any symptoms of carcinoid syndrome (diarrhea, flushing of the face, weight loss, etc.). If these symptoms appear don't hesitate to follow up right away.
