Hello. Im in the same boat. My first post chemo CT scan showed mildly enlarged mesenteric lymph nodes. I had a PET scan a week later which showed two enlarged lymph nodes one was 1.2 mm and the other was .9 mm. Both showed minimal uptake and little if any metabolic activity. My Oncologist thinks they are most likely benign but wanted to try for a biopsy. I wasn't a candidate for the biopsy because they were too small. So we are now on a watch and wait period. I just scheduled my next CT scan for the beginning of June. I guess they can be enlarged for numerous different reasons, cancer only being one of them. For me I have diverticulitis and had Cdiff twice during chemo. Im hoping mine are enlarged for a benign reason and hopefully yours are too. Take care and God bless.
