Hi Lee,
Sorry to hear about your diagnosis, but don't fret too much. You can do this. I am 54 years old and was diagnosed last year with Stage IV SCC w/primary in the right tonsil and 4 node involvement. Debbie is correct when she says to go to a doctor that you are comfortable with, but not necessarily one that tells you what you want to hear. You'll want a doctor that is complete in his approach to your diagnosis and treatment options. If you feel they are missing something speak up and don't take no for an answer. Make sure they explain everything to you so that you understand it. Above all else, educate yourself about the disease and treatment. This site is a good place to find info.
Head and neck cancer, at least this type, usually follows a fairly predictable path. It starts higher up and travels downward through the lymphatic system till it metastisizes to distant locations (lungs, etc...). I say usually because there are always exceptions. But let's assume that yours is following the normal path. It has already spead out of the primary location and is on its way. Your doctor wanting to do a radical might not be a bad idea because of that. His logic may have been to get the cancer at its forward most point and backtrack to the primary. That's not a bad thing. Sometimes the primary is very hard to locate so they will want to cut the path it is travelling. When they went in there and found the affected nodes they had to remove them but without a PET or CT scan they have no idea how far down the path it has traveledl. I would scream for a PET/CT. That way they can see if its gone any further down and deal with it appropriately. A scan would help them find the primary (sounds to me like nasopharyngeal) so they can remove that also.
If your going to have the standard treatment it will include a couple of rounds of chemo, usually a cocktail of 2 drugs like Cisplatin and 5-FU, and around 35 radiation sessions. Make sure you can go to a place that has IMRT or Tomo (3D) radiation options. That'll cut down on your side effects and hopefully spare your salivary glands (you have no idea how important they are). Right now, get your teeth checked (if your doctor hasn't already ordered it). Unfortunately you may have to lose some or all if they are in bad shape. If they suggest a feeding tube, don't worry. It'll help you maintain your weight. Many people can get through without one though (I had one and I'm glad I did). The side effects from the chemo will usually be nausea (try sniffing orange peels and eating ginger candy, it really works) and possibly some hair loss (it will come back). You may or may not get some pretty awful mouth sores. There's some stuff called Magic Mouthwash they can give you that will help but these too will pass. The radiation for me was the toughest but its full effects weren't felt until after treatment was finished. There is a great increase of mucous production (keep an ample supply of paper cups and tissues on hand), burns inside the throat, some irritation of the neck. Don't be afraid of the mask (you'll find out about that). Also, don't be afraid to ask for meds, pain or otherwise. You won't get addicted. And most of all, pay attention to everything they are doing to you and ask questions!
I finished my treatments last January 27th and am doing great. I'm jogging 3 miles a day and lifting weights 4 times a week (not bad for a 54 year old Stage IV cancer dude). I can eat almost as I did prior to treatment but not as hot & spicy. I'm working on it though and it's getting better all of the time. The best part is that I now truly appreciate all of the wonderful things in my life and I know that I've been tested and passed. The same will happen to you. Just remember, you CAN do this. Also, remember that your loved ones will be going through the fear and everything as well. It's not going to be easy for them so be kind. They need your strength and believe me you need there's.
Help is alway available at this site so if you need anything just holler. We're with you.
