I too have been diagnosed with follicular lymphoma. I just had my first pet scan since coming to mayo in April for a 2nd opinion. The pet scan showed better results than the Ct scans I had done at my previous clinic. I just had a bone marrow biopsy and if that comes back clean then I can have a low impact radiation treatment on the affected nodes in my neck. I think the curcumin is probably helping. I take that as well.
