[|Human|] Hi, I have a mass at the top of my left inner thigh which extends to my right hip bone. A biopsy said, no cancer. Doctors at U.C.L.A. don t seem to know why it s there . It s deep behind the groin and they re not sure what to do about it. The biopsy technician only took a half inch of fluid in a tube, The fluid was on the outside of the mass. Would that have shown that the mass itself was non-canceous, and I don t know why he didn t take any of the mass itself. Do you know the answer to that and also what it might be? Thanks. Barbara
[|AI|]  Welcome to Chat Doctor I have gone through your query and understand your concern. It may be that mass is a cyst such as simple bone cyst and aneurysm bone cyst. Probably he was not able to get solid tissue. If tissue is proper then if biopsy shows no cancer, then it is OK. You can discuss with your doctor about it. Hope your query get answered. If you have any clarification then don't hesitate to write to us. I will be happy to help you. Wishing you a good health. Take care.
