Cancer occurs as a result of changes in the genes that control cell growth, which means that all cancer is genetic. These gene changes are inherited in approximately 5-10 percent of families with a history of cancer. While not everyone who inherits a gene change will develop cancer, those who carry the gene change are at higher risk.

The Cancer Genetics Program at Advocate Christ Medical Center offers genetic counseling and testing for people concerned about a family history of cancer, including breast cancer, ovarian cancer and colon cancer. Individuals whose family history includes one or more of the following characteristics of genetic cancer are candidates for genetic counseling:

• cancer diagnosed at an early age
• multiple blood relative with cancer
• bilateral cancer (i.e. both breasts or ovaries, etc.)
• more than one type of cancer in the same individual

Cancer Risk Counseling

Genetic cancer risk counseling assesses the likelihood that an individual will develop cancer, based on a review of the individual's family and medical history. Cancer risk counseling services include:

• a review of the role of genetics in cancer
• a personal cancer risk assessment
• discussion of available genetic testing if appropriate
• referral to other specialists if appropriate

Genetic Testing

Genetic testing determines whether an individual is a carrier of a gene change. Using only a small sample of blood, specialized tests can identify certain genes related to specific cancers. Medical geneticists and genetic counselors help individuals make the best choices for themselves, based on the test results. All test results are kept confidential and are not released without written consent.
