Cancer Risk and Prevention

Genetics and Cancer Risk

Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. Gene changes that start in a single cell over the course of a person's life cause most cancers. In this section you can learn more about the complex links between genes and cancer.
