I have had stage IIIC breast cancer, misdiagnosed, pancreatic cancer, misdiagnosed, , complete whipple,and now they think I have bone cancer in L 2 and my shoulder. I have had pet scan, bone scan, everything. If I get the bone biopsy, what are the risks, and is it dangerous. I am scared my body won t be able to handle more treatments. Fred Hutch is amazing though. Just scared. Thank You.
