So my PET/CT scan results came back: no metastases, the lymphoma is limited just to the lymph node and tonsil, which are both out. :deep sigh of relief:
I'm scheduled for 6 to 8 cycles, with each cycle lasting 21 days. I start the treatment in hospital, but will eventually transfer to outpatient care. They will reevaluate my progress after the first few cycles, repeat the PET/CT scan and adjust the treatment accordingly.
