Why Consider Genetic Counseling?
How can I tell if cancer is inherited in my family?
Sometimes, cancer seems to run in a family. In these families, there may be an inherited factor (a gene change) that increases the risk of family members developing cancer in their lifetime.
A genetic consultation is recommended for persons concerned about their risk for cancer due to a personal or family history of cancer. Some individuals who do not have an extensive family or personal history may still be at increased risk, and would benefit from a genetic consultation.
Clues to inherited cancer risk include:
- Multiple individuals in a family with the same or related cancers (e.g., breast and ovarian; or colon and uterine cancers)
- Early age of onset of cancer (e.g., less than 50 years)
- More than one primary cancer in an individual (i.e., two or more new cancers, not one that has spread)
- Occurrence of a rare cancer (e.g., male breast cancer)
- Occurrence of cancer in a person not exposed to a known risk factor for that cancer (e.g., lung cancer in a non-smoker)
- Existence of a cancer gene mutation in the family
What can be done if my family is at increased risk for cancer?
Cancer screening is very important. If there is a family history of cancer, it may be necessary to begin cancer screening at an earlier age and repeat it more frequently, and genetic testing may be available.
Genetic testing is available for several genes associated with cancer. These tests may confirm a specific gene change (mutation) as the likely cause of a diagnosed cancer, identify potential risks for other cancers or conditions, be used to check if family members are at an increased susceptibility to cancer, and possibly modify medical management. Genetic testing is specific to an individual and family. All results are kept confidential and reviewed with the individual by a member of the Clinical Genetics Service.
Can anyone have genetic testing?
Genetic testing is a relatively new development and is not recommended for everyone. Generally, its use is limited to families with certain types of cancers who meet specific criteria or are diagnosed or are suspected of having an inherited cancer syndrome. Genetic testing for cancer is very complicated and raises many questions. Many factors need to be considered by the doctor, the genetic specialist, and the person interested in testing. Therefore, genetic consultation and risk assessment is recommended before considering genetic testing.
What does it cost?
Genetic consultation The cost of a genetic consult depends upon the extent and complexity of the consult. Initial and comprehensive genetic consults range from about $250-$450, whereas follow-up or limited consults are less. Most insurance plans cover this cost; however, it is your responsibility to contact member services at your insurance company to find out what is covered (the number is on the back of your card).
Genetic testing The cost for genetic testing varies, depending on the gene tested and the method of analysis. Genetic consultation and/or testing may or may not be covered by insurance. This is generally approached on an individual case-by-case basis and a member of the Clinical Genetics Service will assist you in the insurance authorization process prior to pursing genetic testing.
