For breast cancer, there are two groups of patients that may benefit from
genetic testing: Patients who have breast cancer in their family, where
suspicion is high for inherited breast cancer risk, even if they have
never had breast cancer personally or patients who currently have breast
cancer for whom chemotherapy would be recommended if the tumor has a high
risk of recurrence based on a genetic test.
Hereditary Genetic Testing: BReast
CAncer (BRCA) susceptibility genes are the most common inherited breast cancer
genes. BRCA genetic testing is a blood test ordered by a physician, drawn
in our lab and sent to a specialized lab that uses DNA analysis to identify
harmful changes (mutations) in either one of the two inherited breast
cancer susceptibility genes. Mutations to either breast cancer gene —
BRCA1 or BRCA2 — increase the risk of developing breast cancer when
compared with the cancer risk of a people without a BRCA gene mutation.
A positive result may increase risk of other cancer types as well.
Recurrence Risk Genetic Testing: This genetic test may be recommended in a patient with a current breast
cancer diagnosis to determine risk of late recurrence. This is a blood
test ordered by a physician, drawn in our lab and sent to a specialized
lab that uses DNA analysis to identify harmful changes (mutations) in
a large panel of genes, which increase the risk of breast cancer recurrence.
A positive result may indicate the need for chemotherapy.
Talk to your primary care or oncology physician to get a better understanding
if breast cancer genetic testing is right for you.
