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.
When breast cancer spreads to the spine, it's known as bone metastasis. And unfortunately yes, breast cancer that has spread to the bones may spread to other areas such as the brain as well. This happens when cancer cells break away from the primary tumor and travel through the circulatory system. The most common areas for breast cancer to spread are the bones, lung, liver, and brain.
Lung cancer that has metastasized to the bone causes bone pain, usually in the backbone (vertebrae), the large bones of the thigh (the femurs), the pelvic bones, and the ribs. Lung cancer that spreads to the brain can cause difficulties with vision, weakness on one side of the body, and/or seizures.
