There was no evidence of cancer in the node which was removed. YET, the bottom line is that we simply do not know what it is. Might be cancer that is waxing and waning (as AITL is known for), or it might be some other disease process. I will be scanned again in a month and we will see what my lymph nodes and spleen are doing then. Heartfelt thanks to all for their on-going prayers!
The biopsy went without a hitch. I recovered from the anesthesia so quickly that I did not have to return to the recovery room. A suspected cancerous lymph node was removed from my chest wall beneath my left arm. It was the most accessible node which would provide the most reliable test result. Now the wait begins until my next appointment on the 27th, apparently to hear the results of the pathology report. At least we will then know what we are (or aren't) fighting.
Another update of sorts. The last biopsy showed that the cancer has mutated and is now a slightly different (classifiable) form. Sadly, this new form is resisting treatment, so treatment has been stopped. There is no explanation for the cause of this, and once again, all of the experts are stumped. Due to some level of uncertainty about the last biopsy, I will be scheduled for another biopsy, probably next week. That one should provide a definitive result.
