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).
When prostate cancer spreads beyond the prostate to another organ, most frequently it spreads to the bone. Prostate cancer that spread to the bone is still prostate cancer when doctors look at it under the microscope. It is still treated with therapy for prostate cancer. A man whose prostate cancer spread to the bone does not have bone cancer.
