      Good question Nadine…

      Cancer is a complex group of diseases with many possible causes, including genetic factors; lifestyle factors such as tobacco use, diet, and physical activity; certain types of infections; and environmental exposures to different types of chemicals and radiation.

      These factors somehow cause changes in the body’s cells. If one of these changed cells survives and divides when it should under normal circumstances die, then cancer develops.
