So, I had the follow-up appointment to discuss my CT Scans today, and it looks as though the cancer (!) has spread to a lymph node. Another blood test (also done today) will determine whether I'm Stage IIA, B, or C. I'll be seeing an Oncologist tomorrow and will hopefully get some perspective on treatment and what that will mean for me. Luckily, the spread wasn't extensive, and the treatment course appears to have a high success rate. Fingers crossed.
