Today was my lymphoscintigraphy - a process by which the lymphatic system is mapped through use of a radioactive isotope that was injected into my neck/jawline in four areas proximal to the melanoma. The needles here were 25 gauge. After several minutes passed - letting the isotope spread through my lymphatic system - a few five minute scans were taken using a SCENT CT (google failed me on that one) in order to find the sentinel lymph nodes (lymph nodes closest to the site of the melanoma and if my cancer has spread, the most likely to indicate as such). I will not know if the cancer has spread (or not!) until the tissue and lymph nodes are removed during surgery and tested (I've been told results will take a week). The technologist marked the two sentinel lymph nodes with blue paint (as shown below). I then had a 20 minute 3D full body scan - during which I fell asleep...hehe. This gives a much clearer image...blah blah blah. I asked questions, but it was a lot of information.
I'll post another update as soon as I'm home.
