You can always take them to another hospital for another opinion....
My original path report came from Providence, and it mentioned that there were some traits that looked like medullary carcinoma, but that it looked more like ductal. U of M confirmed that it was ductal. When I spoke to my rad onc about it, who was on staff at both facilities, he said that if Providence had a question, THEY would send it to U of M to be read.... so maybe it is true, that they really are the experts in the area?
Anyway, don't just accept their word unless you feel comfortable.
