I am having an aspiration from my femur next week. They are trying to clarify why my bone lit up in a nuclear scan. They said it may have lit up from a femur fracture, 11 months ago. Or, it could be part of a MRSA infection I had in my hand, 4 1/2 months ago. If it was cancer, in any form, would they find that out through this test as well? Or do all cancer tests through aspirations come from the bone marrow in my hips?
