Genetics and Cancer

Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. In this section you can learn more about the complex links between genes and cancer, as well as genetic testing and how it is used.

Family Cancer Syndromes

Cancer is such a common disease that it is no surprise that many families have at least a few members who have had cancer. Sometimes, certain types of cancer seem to run in some families. But only a small portion of all cancers are inherited. This document focuses on those cancers.

Genes and Cancer

Advances in genetics and molecular biology have improved our knowledge of the inner workings of cells, the basic building blocks of the body. Here we review how cells work, how they can change to become cancer, and how we may be able to use our understanding of these changes to better prevent and treat cancer.

Genetic Testing: What You Need to Know

Genetic testing can be useful for people with certain types of cancer that seem to run in their families, but these tests aren't recommended for everyone. Here we offer basic information to help you understand what genetic testing is and how it is used in cancer.
