Genomics is the study of genetic (hereditary) factors behind diseases. The Utah Cancer Control Program (UCCP) receives Centers for Disease Control and Prevention (CDC) funding to increase the use of family health history, genetic counseling, and testing for hereditary cancers.
BRCA1 and BRCA2 are genes that protect you from getting certain cancers. If you have a mutation (change) in the BRCA1 or BRCA2 gene you are more likely to get breast and/or ovarian cancer.
Even men who have a mutation are at risk for prostate cancer and breast cancer. Both men and women with these mutations (changes in genes) are also at risk for pancreatic cancer and melanoma.
BRCA1/2 mutations (changes) are more likely to be seen in families with a history of breast and/or ovarian cancer. Knowing if you have a BRCA1/2 mutation can help you to make choices that can reduce your risk of cancer.
Hereditary colorectal (colon) cancer and Lynch Syndrome
If you have Lynch Syndrome, you are much more likely to develop colorectal cancer, a type of uterine cancer called endometrial cancer, and other cancers. Blood relatives such as grandparents, aunts, uncles, nieces, and nephews are also at a risk of having Lynch Syndrome. Lynch Syndrome is more likely in families where people have had colon cancer before age 50, or in women who have had uterine cancer. The only way to know if you have Lynch syndrome is through genetic testing. Knowing if you have Lynch Syndrome can help you make choices that can reduce your chances of getting colorectal cancer.
Knowing and acting on your family health history is a way to protect your health. Collect your family health history and share it with your doctor at your next visit. Your doctor can use it to help you prevent the diseases you may have a risk of developing.
