In Hereditary Non-polyposis Colorectal Cancer (HNPCC) and Familial Adenomatous Polyposis (FAP), you inherit a normal gene from one parent and a damaged one from the other parent, or acquire a damaged gene at conception. All the cells in your body will then contain one normal and one abnormal gene. Over time, the normal gene may become damaged too. When there are two damaged genes, the cells are not under normal control and cancer develops.
