About 1 in 3 people in the United States will develop cancer during their lifetime,1 so it’s not uncommon to have many cancers in the same family. Less often, cancers in a family are strongly linked to an inherited gene mutation that is part of a hereditary cancer syndrome.  

Our hereditary cancer solutions help close the gap between the unknown and the path forward. A complete portfolio of hereditary cancer tests, services, and expert analysis from our on-staff genetic counselors help you understand your patients’ risk and are the first step in our approach to supporting a patient’s cancer journey.

Tests include:

  • Comprehensive and guideline-based hereditary cancer panels
  • Cancer-specific panels
  • Hereditary cancer syndrome panels
  • Single-gene and single-site tests

Our genetic counselors are available to consult about test selection and results interpretation. To speak with a genetic counselor, call 1.866.GENE.INFO (1.866.436.3463).
