Second PET/CT Scan Tomorrow

They are going to check out my positrons again with the combined PET/CT scan tomorrow. I have to fast 6 hours before the test. They will inject me with glucose and then they will scan me. The PET scan part will look for areas that have increased metabolism, or uptake. Cancer cells have increased metabolism. We are looking to see if the spots on my hip, back and sternum shrink. If the spots on my hip shrink, then the chemo is working. If the spots on my back and sternum shrink, then we know the chemo is working on them, and we also know that they are cancer, and then we know that I am Stage IV. It may not make any difference, though, because I am probably just getting 6 rounds of chemo whether I am stage I or IV.
