Hereditary Cancers

While the majority of cancer is sporadic and occurs by chance, approximately 5-10% is hereditary and occurs because an individual was born with a harmful change in a gene that increased their risk to develop cancer. In general, it is estimated that approximately 5-10% of breast cancer, 5% of colorectal cancer, and up to 25% of ovarian cancer is due to a harmful change in a gene associated with hereditary cancer. Other types of cancer may also be hereditary.

Hereditary Cancers
Hereditary cancers are caused by pathogenic variants (harmful changes) in certain genes passed from one generation to the next. These pathogenic variants are usually inherited from a parent and can significantly increase the risk for one or more cancers.

Sporadic Cancers
Sporadic cancers are caused by a random event and are not passed from one generation to the next within a family. Sporadic cancers occur more frequently as we get older due to environmental and lifestyle exposures such as diet, weight, exercise, smoking, and alcohol use among others.

When is Genetic Testing for Hereditary Cancers Appropriate?

Individuals with a personal and/or family history of the following may be at risk for hereditary breast, ovarian, and/or endometrial cancer. Family history includes first, second, and third-degree blood relatives (including parents, siblings, children, aunts/uncles, cousins, and grandparents).

  • Cancer at a young age (under the age of 50)
  • Rare cancers at any age (such as male breast cancer, ovarian cancer)
  • More than one type of cancer in the same individual (also referred to as multiple primary cancers)
  • 10 or more colon polyps
  • A known genetic alteration in the family
  • Multiple cases of cancers on one side of the family spanning multiple generations
  • An individual of Ashkenazi Jewish descent with breast, ovarian or pancreatic at any age

It is important to provide detailed information on the personal and family histories of cancer, including ages of diagnosis, pathology, and relationship between family members. This information can help determine if testing is appropriate and which test is medically necessary, as well as may impact insurance coverage.
