Hereditary cancers lurk in the shadows of DNA. The genes that cause hereditary cancers are passed down from parents to children — they don’t skip a generation. If one parent has a genetic mutation, their children will have a 50/50 chance of inheriting the cancer-causing mutation.

Today, research shows that hereditary cancers account for 10 percent of all cancers effecting both men and women. It is widely believed that further research will revel even more hereditary genetic links to cancer.
