Ray,
My sister is also 49 and had a very similar diagnosis as you-I just posted that there is no trace of her cancer left as of today. I will say that one of her nodes was a bit enlarged initially so they treated her with aggressive protocol. She has not had a dissection as many here have, but there is a lot of information to be learned on that subject. Use the search engine at the top of the posts page and you'll find many posts from several "experienced" people.
Just being here is a good place to learn and help. You will be on my thoughts!
