Phosphorus is an important element which is useful for the synthesis of bones and teeth. Apart from that phosphorous is also useful in maintaining normal functioning of the nerves and the contraction of the muscles. A huge chunk of the phosphorus present in our body is in the form of bones.
If cancer has spread to another location in the body, it is called metastatic cancer. The most common place kidney cancer spreads is to the lungs, but it can also spread to the lymph nodes, bones, liver, brain, skin, and other areas in the body. For kidney cancer that has spread to one specific part of the body, such as the lungs, surgery may be able to completely remove the cancer.
This is how doctors can tell that it is cancer that has spread from another part of the body. Metastatic cancer has the same name as the primary cancer. For example, breast cancer that spreads to the lung is called metastatic breast cancer, not lung cancer. It is treated as stage IV breast cancer, not as lung cancer. Sometimes when people are diagnosed with metastatic cancer, doctors cannot tell where it started.
