These are difficult questions to answer, however, the latest information in cancer research has shed light on how cancer develops, the genetics of cancer, and ways cancer can be prevented.
Cancer prevention aims to prevent cancer from ever developing.
In most cases cancer is the end result of a process that took many years to develop. The common pathway leading to cancer results from multiple instances of DNA damage or mutations. These DNA changes arise from a combination of environmental exposures and inherited or genetic factors. Diet and lifestyle are two factors contributing to cancer over which we have control. Although most people believe that cancer prevention means avoiding carcinogens, in reality that is not a practical approach because most such substances are a part of our everyday life, in our diet, through environmental exposures, and as by products of our own metabolism.
