They've gone the distance with this! I had a bone marrow biopsy. I was seriously B12 deficient but I was able to correct that with a very high powered B complex supplement (4,383X min RDA)- went from <150 to 352 (norm being ~200). They're following me for MGUS since they detected a high level of IGG in my blood. They also suspected stomach cancer so I had an endoscopy and biopsy to rule that out (a scan I got showed thickening of the antrum). I get annual ocult fecal blood tests (always pass). Passed the PET/CT and 3 Spiral LDCT covering entire body - found nothing. I'm a medical mystery! It was supressed during treatment, never returning to pre-tx levels. I also have Baro-reflex failure because of damage to the cartid artery and vegas nerve. It's been a real joy but others have it far worse. I expanded my medical team to include an infectious disease specialist and pulmonologist. I'm still seeing my H&N surgeon, RO and MO.
