Oscar,
Welcome...I guess, I always feel funny saying that to new members. I don't come out of the shadows and post much anymore, but your story is very similar to mine. From the node to being told it was a cyst and then waking up with a big J inscision along the whole left side of my neck. We were even the same age at diagnosis. The only difference is my primary was in the base of tongue. And I only have one child but he was 6 when I was going through my treatments last year.
This past Oct 5 was my one year anniversary and things have been clear thus far. I still deal with the mental side of this dreadful disease but I like you have have a family that I need to be here for. As you'll see from my signature block I had both radiation and chemo. If there was any other treatment I would of had that too.
There are some tough times ahead for you. This board helped me through both physical and mental issues and still does. I found comfort here and I know you will to. If I can help further post here or you can PM me.
Keep us posted and know that you are in my prayers.
Tim
