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.
Neurologic complications continue to pose problems in patients with metastatic prostate cancer. From 15 to 30 percent of metastases are the result of prostate cancer cells traveling through Batson's plexus to the lumbar spine. Metastatic disease in the lumbar area can cause spinal cord compression.
Cancer can spread to any bone in the body. The most common sites of bone metastases are the vertebrae (bones of the spine), ribs, pelvis (hip bone), sternum (breastbone) and skull. Sometimes only one area of bone is affected. Sometimes metastases develop in several bones at the same time.
