Cancer Genetics Contact number | 202-476-4685

The Divisions of Genetics and Metabolism and Oncology established the Cancer Genetics Clinic to help family members understand their personal risk of developing cancer and to learn more about the risk for their loved ones. Our mission is to identify individuals with a greater likelihood for certain types of cancer and provide early detection and treatment. Ultimately, our goal is to prevent the development of cancer or additional cancers altogether.

Experts in Pediatric Genetics and Oncology

Our team is a leader in the recognition and care of patients with newly recognized cancer predisposition syndromes. A person with a cancer predisposition syndrome is at an increased risk to develop cancer sometime in his or her lifetime. The Cancer Genetics Clinic sees many patients, including:

  • Children with cancer
  • Children with a past history of cancer
  • Children with early-onset cancer and rare forms of cancer
  • Children with a family history of cancer
  • Parents of a child with cancer
  • Couples who want to learn more about the risks to their other children or future children

Dedicated clinical geneticists and oncologists available for individuals and families evaluated through the clinic. The Cancer Genetics team includes Joyce Turner, MS, CGC, a genetic counselor, and Leslie Doros, MD and Miriam Bornhorst, MD, pediatric oncologists.

Genetic Counseling and Testing

Every family's situation is unique, and the team at Children's makes time to address individual concerns. The genetic counseling process involves reviewing a family’s medical history to better understand the types of cancer and pattern of inheritance in a family, as well as to determine whether an individual and family may be at risk for cancer predisposition syndrome.

During the genetic counseling session, our specialists educate patients and their family members about the specific cancer syndrome in question, how it is inherited, and who in the family may be at risk. The discussion includes:

  •  available testing options
  •  the pros and cons of testing
  • whether testing is the most appropriate course of action for the family
Depending on the medical findings, a consultation may also involve an evaluation by a geneticist.

Families should understand that genetic tests are different from other blood tests. Insurance preauthorization (approval) is usually necessary before testing. Once obtained, the testing process may take a few weeks to a few months, depending on the specific test being performed. When test results become available, a follow-up consultation is scheduled to review the meaning of the results and to develop an appropriate plan of care.
