If genetic testing is performed but does not identify a harmful genetic variant, or if testing is declined for any reason, DNA banking is another resource available to ensure the ability for future genetic testing of one’s DNA. This is primarily for the benefit of family members, and can allow for the most informative genetic testing and interpretation in the family (since it is always recommended to start testing in a family member who has had the cancer of concern). DNA banking is available through many laboratories throughout the country at relatively low cost, and can be facilitated by your genetic counselor or other providers. If you pursue DNA banking, it is important that you keep copies of the paperwork and inform your family members of this resource for them.
