Genetic Services for Cancer Diagnosis: When, Where, How
If cancer runs in your family, when do you need genetic services?
Many factors can be present in a family that may call for genetic services. Below is a general checklist of factors. These may suggest a higher risk for familial cancer or a heritable cancer syndrome. The symptoms of genetic diseases may look like other health problems. Always talk with your healthcare provider for a diagnosis.
___ A family history of multiple cases of the same or related types of cancer
___ One or more family members with rare cancers
___ Cancers occurring at an earlier age of onset than usual in at least 1 family member, such as colorectal cancer before age 50 or breast cancer before age 40
___ Bilateral cancers, which is when 2 cancers develop independently in a paired organ, such as both kidneys or both breasts
___ One or more family members with 2 primary cancers (2 original tumors that develop in different sites)
___ Ashkenazi (Eastern European) Jewish background
Where to find genetic services
Genetic services are often available in large hospitals or health centers. The local phone book or healthcare provider directory may help you find someone near you. Talk with your healthcare provider for more information.
The National Cancer Institute has a website where you can search for cancer genetic providers by location. This Cancer Genetics Services Directory is a directory of experts who offer services like cancer risk assessment, genetic counseling, and genetic susceptibility testing.
