This is not something that you would find on a Pathology report. I suggest that you talk with your Physician and get a detailed explanation of the biopsy report. The report should contain the information as to whether the tissue contained cancer cells. Regards .....
I assume you don't have the results back yet.
It's hard to tell just looking at it like that. They have to slice it up and put it under a microscope. But I know what you mean. The doctor showed me my biopsy samples too and chicken fat is a good description for it. Mine was negative, but they didn't know till they looked under a microscope. However, the doctor said white tissue is usually health tissue, so hopefully you'll get some good news.
