I have been reading all this for some time now and this is getting on my head !

Amy ,What the hell do the doctors mean by guessing that spot on the lungs are Cancer ? I would suggest you to please take a stand here and ask ur doc to explain things .

I dont know the past but have you taken any other docs opinion ?
Trust me its always better to have a doc who atleast have time to talk to you and understand your questions.
It seems to me that all your hospital visists have been kinda business for the medical team rather than treatment.

You are doing a good job by fighting back but its matter of life and death, so your stand is correct, Never hesitate to take second opinions and never feel your expecting more from medical team may that be your doctors or other staff.

As for your mom she is brave woman, hats off to her courage.
Please do take care of her and yourself and dont give up on anything !
You both are there in my prayers
