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.
However, just because breast cancer has spread to the spine doesn't mean that it will spread to other areas. Doctors can treat the new tumors with radiation and new medications called bisphosphonates can block the progression of tumor cells in the bone and prevent the cancer from spreading to other organs.
Prostate cancer most commonly spreads to the bones and lymph nodes. It can also spread to, or press on, the tube that carries urine through the penis (the urethra), the bladder, the tubes that carry urine from the kidneys to the bladder (ureters) and part of the bowel (rectum). More rarely, prostate cancer may spread to other parts of the body including the lungs and liver.
