Hugs, hugs, hugs.. so far away and not knowing can be so difficult..
Just food for thought here, not sure if the diagnosis is cancer in the lymph nodes or that is where it presented. My daughter had thyroid cancer, the secondary site was a lymph node so that is where we saw it first....but it was originally in the thyroid.. and sometimes Thyroid cancer, if it is papillary can be an easy one..
Anyway.. here is how I try to think... until I know what it is, I cannot beat myself up with worry. Granted I am here with my DH who is battling cancer and my children are only an hour away.....and treatment is in the city where my children live so they do not deal with the being so far away thing, but I try, notice I said try, to take it as it comes. It is a battle, think rollercoaster, and there will be good days and bad, and you cannot change it by worrying and making yourself sick... Another thing we say in this family is... it is what it is.. we have no control, we just deal.
We are here for you if you need to talk, this board is great for help, prayers, hugs whatever you need and we are here for you. Please let us know how he is doing....also I agree with poster, maybe he could sign that release so that you could talk to the doctor directly.. Our oncologist, who we love, actually emails back to my daughters when they have questions.. he is the head of the department in a big Boston hospital, so calling can sometimes be difficult to get through to him, emergencies aside, but emailing is great.. maybe you could ask for that??
