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.
Spread to Bone. Roughly 30 to 40 percent of people with advanced lung cancer have spread (metastases) to bones. The most common bones to be affected are the spine (especially the vertebrae in the chest and lower abdominal area), the pelvis, and the upper bones of the arms and legs (humerus and femur).
Prostate, breast, and lung cancers are most likely to spread to the bone. However, other cancers are not excluded. Bone metastases do not begin from the bones but move there from the primary tumor site. On the other hand, primary bone cancers are rare cancers where the primary tumor actually starts in the bone.
