I have 2 go for a bone biopsy for a hard,egg size lump on the frontal lobe of my skull. The surgeons don't seem to know what it is- hence the biopsy, but they seem to think it is primary malignant bone cancer. I was wondering if anyone had had anything similar to it and what kind of treatment they had- already had 2 CT Scans and full body xrays done. Thankyou for any advice.
