The story of your diagnosis is quite typical for NETs/carcinoid patients. Many of us were being tested for something totally unrelated and had no symptoms. This type of cancer often has no symptoms. Fatigue is very common with this cancer.

It is always wise to consult a NET specialist. NET specialists are not in every oncology clinic. At Mayo Clinic, all three locations have NET specialists. If you are interested in an appointment
for a second opinion, here is a link with appointment information: http://mayocl.in/1mtmR63.

If for any reason an appointment at Mayo is not possible, here is a link from the Neuroendocrine Tumor Research Foundation with NET specialists in the U.S.: https://netrf.org/for-patients/neuroendocrine-tumor-doctor-database/page/8/

Have you considered obtaining a second opinion?
