Do get a second opinion but be sure they are a NET specialist. My husband was written off by a top Boston hospital a year and a half ago so we went to a new facility and have had good results. Please keep in mind NET’s are different for every individual. I see people here who have been treated for many years. There are new therapies coming out constantly. My husband has had embolization, two types of chemo, monthly octreotide shots, and is currently undergoing PRRT (radiation) therapy. His first doctor said he would be gone in 6 months. That was 20 months ago. Keep fighting!!
