A teacher's assistant is not typically required to hold a Bachelor's Degree, so the average pay is much lower than that of the teacher in charge. A teacher's assistant averages about $21,000 yearly with a slight range between $19,300 and $27,400.
However, just because breast cancer has spread to the spine doesn't mean that it will spread to other areas. Doctors can treat the new tumors with radiation and new medications called bisphosphonates can block the progression of tumor cells in the bone and prevent the cancer from spreading to other organs.
Cancer can spread to any bone in the body. The most common sites of bone metastases are the vertebrae (bones of the spine), ribs, pelvis (hip bone), sternum (breastbone) and skull. Sometimes only one area of bone is affected. Sometimes metastases develop in several bones at the same time.
