So glad you had a pet scan BEFORE surgery! I had squamous cell cancer removed and multiple tumors removed. One tumor came back as cancerous and now we are trying to figure out what to do next. 1. Remove all lympnodes in groin area because the tumor was exactly in the middle, followed by 2 rounds of radiation. Risk factor here Lymphedema, which is painful and debilitating. 2. 2 rounds of radiation in the pelvic area and 1 round of radiation targeting the spot where the tumor was. 3. Do nothing now with a yearly follow up.
Sounds to me like you are on the right path and everything is being accessed before surgery! Good Luck!
