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).
Tumors that start in spinal tissue are called primary spinal tumors. Tumors that spread to the spine from some other place (metastasis) are called secondary spinal tumors. Tumors may spread to the spine from the breast, prostate, lung, and other areas. The cause of primary spinal tumors is unknown. Some primary spinal tumors occur with genetic defects.
