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 that begins in an organ, such as the lungs, breast, or prostate, and then spreads to bone is called metastatic bone disease (MBD). More than 1.2 million new cancer cases are diagnosed each year. Approximately 50% of these tumors can spread (metastasize) to the skeleton.his type of damage is most common in cancers that have spread to bone from the lung, thyroid, kidney, and colon. Alternatively, new bone can form in response to the cancer spread. This new bone, called osteoblastic, grows abnormally and causes the bone to be weak and deformed.
