Unfortunately not uncommon! We were led to believe my mother only had 3 tiny tumors left on her liver and come to find out that there are more than 3 (never been told an exact number) and that the radiologists sometimes dont mention tumors that are under 2cm because sometimes the ones that small arent even picked up by the CT. It seems that when your life is on the line, they should measure every single tumor that they see regardless of how small it seems to them. Every dang tumor starts as just a few cells! They keep saying that she has had 30% shrinkage with each of her CTs but, geez, how can you feel confident that they are even reading it right??? It is frustrating and I seriously dont understand it, but i have absolutely NO idea of what to do about it!!! I guess we are at the mercy of the radiologists.
