BRCA Gene Test for Breast and Ovarian Cancer Risk
Livontaglobal
The BRCA gene test is a blood analysis that employs DNA analysis to find damaging variations (mutations) in either of the two genes that increase the risk of developing breast cancer, BRCA1 or BRCA2. A comparative study shows that the general population who inherit mutations in these genes are more likely to develop ovarian and breast cancer.
Those who are likely to have an inherited mutation due to a personal or family history of breast cancer or ovarian cancer are offered the BRCA gene test. For those who have a typical risk of developing breast and ovarian cancer, the BRCA gene test is not frequently administered.

The sample is delivered to a laboratory for DNA testing. Saliva is one of the additional sample types that may occasionally be gathered for DNA analysis. Consult your doctor if you’re considering a saliva DNA test and have a family history of cancer.
