I had cat scans and mri tests that showed I had 6 tumors in my body. After surgerically removing them all I later found out that I had one on my upper arm. My question is what kind of test would have shown that I had a kidney cancer tumor on my arm?? The doctors told me I would have to look for tumors on my arms and legs myself and then they would take a cat scan or mri on that location. I guess when you have a full body can scan that doesnt' really mean full body. Thanks Sharon13
