You have a good chance of defeating most kinds of cancer if it is caught early. Cancer is caused by changes in genes that regulate cell growth and differentiation, and some of these are passed from One Generation to the Next (PDF). In the Sutter Health network, we offer genetic testing for cancer, including BRCA1 and BRCA2 gene testing.
Genetic counselors will review your family’s cancer-risk profile. If that history suggests a higher than normal degree of risk, we may suggest genetic testing to seek out known gene mutations that leave you and your children vulnerable to certain types of cancer. These mutations cause cancer in many organs, including the breast, ovaries, prostate, thyroid, kidney, bladder, colon, liver, stomach, skin, eye and pineal gland.
Testing is done on a small amount of body tissue or fluid, such as blood, saliva or the amniotic fluid surrounding a fetus. An appointment will be scheduled to discuss the results when they are available. A positive test does not guarantee that you will get the cancer, but it does enable you or your loved one to be screened at regular intervals.
Discuss with a physician or genetic counselor the limitations, consequences and potential results of genetic testing for cancer before getting tested. You should consider testing if:
- Your mother, father, siblings or children develop cancer.
- You had cancer at an early age.
- A family member had cancer at an early age.
- A family member had a positive gene test for a cancer with a genetic cause, such as breast or ovarian cancer.
- You are of Ashkenazi Jewish heritage.
