"Cancer researchers, at the most basic level, focus their energy on what makes cancer cells start in the first place and what makes it metastasize. Now cancer does not have to metastasize. The cancer cells can die at any stage of the process or they can even make those tiny tumors and those tumors can just sit there and not grow. The factors that seem to influence metastasis are genetic or environmental factors or maybe both. Now, the environmental factors can include chronic inflammation caused by environmental triggers such as infections, smoking, or obesity can further boost metastasis by helping processes like developing new blood vessels and immune evasion. Cancer can spread to almost any part of the body, but different types of cancer are more likely to spread to certain areas than others. Most common sites where cancer spreads are bones, liver, and lung. The goal of treating metastatic cancer is to control it by stopping or slowing its growth. Some people can live for years with metastatic cancer that is well controlled. The treatment depends on the type of primary cancer, where it is spread, previous cancer treatments, and general health.
