Hello @rita2023 and welcome to the NETs discussion group on Mayo Clinic Connect. You are wise to seek a GA 68 scan. Here is some information about it from a radiologist at Mayo Clinic in Rochester, MN.

You might want to check with your insurance to see if there is a cancer center nearby where you can have this test done.

I am a 20-year survivor of NETs, having had three surgeries for NETs in the upper digestive tract. So far, surgery has been the only treatment needed.

If you care to share more, when was your parent diagnosed with a NET? Has surgery been suggested?
