Julieann, yours is another cautionary tale. I have to give credit to Gordon for not being satisfied with the initial false negative biopsy. I was quite annoyed with him, because I sure wanted to believe it was nothing. However, we both thought the the lump should come out, because as Gordon said "I don't know what it is, and I don't know why it's there. Until I do, I won't be satisfied." (or words to that effect). We were lucky to get to the right surgeon who was older and very experienced with this type of cancer.
I guess diagnosis can be hit and miss and it sounds like you did all the right things - pushing for answers when you knew something was wrong. I wonder how many people die because they assume everything is OK because their doctor said so? Anne
