Do you have extensive stage lung cancer? It seems like they offer immunotherapy if you are extensive stage or if you've had a recurrence. Find out what they are recommending and ask your team about it. The people I've known who have done immunotherapy have had great success with it and very few if any side effects. It has kept their cancer stable. That's a good thing! You usually don't get scans until your chemo and radiation treatments are done. At that point they determine if the treatment worked. It's frustrating going through the treatments and not knowing if they are working. SCLC usually responds quite well to the initial treatments. I would not be too concerned about the immunotherapy, but please talk with your doctor about it. Get on the portal and express your concerns. Someone should be able to talk to you about it. You need to have some acceptance and peace of mind before starting. Your attitude will make all the difference. You will get through this. I'm 6 mos out from treatment. I never thought I'd feel this good again. Have hope! Wishing you all the best. Would love to hear what you find out. VLPR
