In the realm of breast cancer detection and prevention, genetic testing plays an increasingly significant role. However, understanding who should consider undergoing this testing can be complex. At Great Lakes Medical Imaging in Buffalo, NY, we believe in empowering you with the knowledge to make informed decisions about your health.

Unraveling the Connection: Genetics and Breast Cancer

While not all cases of breast cancer are hereditary, certain genetic mutations, such as the BRCA1 and BRCA2 genes, significantly increase the risk. These mutations may be passed down from parent to child, increasing the likelihood of developing breast cancer.

Considering Genetic Testing: Who is it for?

Genetic testing for breast cancer is not necessary for everyone. Instead, it is recommended for individuals who have specific risk factors, including:

• A personal or family history of breast cancer diagnosed at a young age
• Multiple family members who have been diagnosed with breast or ovarian cancer
• Ethnicity, as certain ethnic groups like Ashkenazi Jews have a higher prevalence of BRCA mutations
• A family history of male breast cancer

The Genetic Testing Process

Genetic testing for breast cancer risk typically involves taking a blood or saliva sample. The sample is then analyzed in a lab to identify any changes in the BRCA1, BRCA2, or other cancer-related genes. It is crucial to remember that testing positive for a genetic mutation does not guarantee you will develop breast cancer—it merely indicates a higher risk.

Understanding the Implications

Testing positive for a BRCA or other gene mutation can guide strategies for breast cancer prevention and early detection. This might include increased surveillance, prophylactic surgery, or medications to reduce risk. Moreover, it provides vital information for other family members, who might also carry the mutation.

At Great Lakes Medical Imaging, we offer a variety of screening and diagnostic services, including Breast Ultrasound, 3D and Digital Mammography, and Breast MRI, to support those who carry a higher genetic risk for breast cancer.
