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 people have cancer in bones, often it is cancer that has spread there from elsewhere in the body. This is metastatic cancer. Even though it spreads to bone, it is not considered bone cancer because the tumor cells are from the primary cancer. For example, a person with lung cancer that has spread to the bone is considered to have lung cancer with metastasis to the bone -- not lung cancer and bone cancer.
