Empower your patient’s decisions with Hereditary Cancer testing

Approximately 1 in 3 people in the US will be affected by cancer during their lifetimes. 5-10% of those cancers are believed to be due to a hereditary predisposition.

These hereditary predispositions may be shared by a person’s family members including parents, siblings, and offspring. For example, if a mother or father is found to be a carrier for a pathogenic BRCA2 variant, each of their offspring also have a 50% chance of inheriting the pathogenic variant, which may lead to an increased risk for developing certain types of cancer

Assessing your patient’s DNA for pathogenic and likely pathogenic variants can help other family members to assess their risks for potential cancer development.

Through Baylor Genetics, clinicians can order a wide range of tests including single gene studies, disease-specific panels, and comprehensive studies. Screening allows for a more accurate determination of personal and familial cancer risks and may potentially inform medical management decisions. Hereditary cancer screening is suitable for individuals who are suspected of having an inherited cancer syndrome or have a personal history of cancer suggestive of an underlying genetic condition.
