Your welcome. Someone helped me when I was starting out too.
Your questions are worthy of a NET specialist answers or even a second opinion with another NET Doctor and an aware social worker who can answer and advise you. I like Amy Allen MSW at Mayo Clinic in Rochester MN.

Off the top of my head..
The concern that you are symptom free at the moment and that you might get side effects from the Lanreotide is a real concern. I surmise, that how difficult or not the side effects would be is difficult to determine until one tries. Is slowing down progression worth the side effects?

Your second question: "I do not understand why I could not just go straight to radiation treatments which are believed to shrink the actual ileum tumor." also deserves a response, and again a NET specialist with a solid expertise and experience in the field is needed.

I respect you searching to find the right resources and hope you continue to work finding what you both deserve and need.. It is important to find the NET medical team we click with.
