Robert -- I'll chime in too with encouragment to get your appointment moved up. It can happen if you throw your weight around enough...
My wife is one of those bulldog types and she was an amazing advocate for me the day I was diagnosed with SCC back in October. THey were going to do a C-T scan in a week, and do this and that at a later date, etc. But after my wife worked her magic and charms (and refused to hear that it couldn't be done sooner), I had a ton of stuff done that very day...
Sometimes you have to be a bulldog on these things but it is your health and your life. You are worth it even if you ruffle some feathers...
