It was just discovered have bone cancer in my shoulder, upper arm, spine and hips only becuase I am having so much pain. In 2009 I had breast cancer. The doctor's assumed the breast cancer had metatasized to the bone. I had a biopsy this week from my spine and the results show the cancer is endimetrial uterine origin. I had a Pet Scan and showed no cancer in any of my tissue. The doctors say it is a mystery.
Has anyone every heard of this happening?
