Hello @grandfather2, and welcome to the NETs support group on Mayo Clinic Connect. It sounds like this neuroendocrine tumor is a new diagnosis for you. How long ago was your surgery?

I see that @michellehcapouch has already posted to you about her good experience with these injections. As you are considering this type of treatment, I would invite you to a discussion group where others share their experiences with these injections. Here is a link to one of those groups:
https://connect.mayoclinic.org/discussion/any-one-with-neuroendocrine-tumors-getting-the-shot-once-a-month/
Here you will meet @vinnie694, @lindabees, @californiazebra, and others. I suggest you post any questions or concerns about the monthly injections in this discussion group.

Here is a link to another NETs discussion group where you can read and post about liver metastasis:

How are you feeling since your surgery? Any problems with digestion?
