Hello Francis:

I appreciate your asking about NETs. As @tomewilson said, NETs is a form of cancer. It is rare, however, and many people have never heard of it before. For many of us, we first learned about it when we were diagnosed. Here is some information from the Mayo Clinic website that explains it further. Just click on the link and you can read more about it.

Would you care to share why you are interested in NETs? Have you or a family member been diagnosed with this disorder?
