I have had 2 melanomas removed from the leg and part of the followup is a chest xray every 3 months to make sure it doesn't reappear (apparently likes to come back in the lungs). I had my 3 month appt and the xray tech takes a shot, comes back all worried, I need to redo it! After three tries, she say's your staying to talk to the dr. right??? Don't you just hate the waiting. Best of luck to you!
