More information about Cancer Genetics CounselingWhile all cancer involves changes in the genes of cell, not all cancer is hereditary. In recent years, a number of genes related to inherited predisposition to cancer have been identified. In fact, it is estimated that between 5-10% of all cancers are due to an inherited gene mutation. Individuals who carry a mutation (alteration) in a cancer susceptibility gene have a significantly increased lifetime risk to develop cancer compared to the general population's risk. By taking into consideration personal and family medical histories, a physician can identify patients and their families who would benefit from meeting with a genetic counselor for a hereditary cancer risk assessment. Genetic counseling for cancer risk assessment may be appropriate for anyone with:
Genetic counseling for cancer risk assessment involves a review of the pattern and ages a diagnosis of cancer in the family and a discussion of whether this is suggestive of an inherited predisposition to cancer. This discussion includes a review of basic genetics/inheritance principles, information about whether genetic testing is available, the cost, and the risks, benefits, and limitations of these types of tests. A genetic test for cancer susceptibility is not diagnostic; that is, it does not reveal the presence or absence of cancer, but whether an individual has an inherited tendency or predisposition to cancer. Risks involved with genetic testing are not physical risks, but involve the psychological impact of such testing. For this reason, education and counseling before and after genetic testing is recommended. If you are interested in making an appointment for genetic counseling, please feel free to call Aurora's Cancer Genetic Counseling Program at 877-641-2502. You also can print a referral form for your doctor.
