Breast Cancer Awareness: Genetic Testing

Genetic testing and breast cancer.

October is Breast Cancer Awareness Month. Check Yourself, Protect Yourself.

Genetic testing is a crucial tool to evaluate the likelihood of breast cancer risk, especially for those with a family history of the disease. The BRCA1 and BRCA2 genes, in particular, have been linked to a higher vulnerability to breast and ovarian cancers.

How genetic testing is done

Mutations in the BCRA genes can be identified through a blood or saliva sample. If you carry a mutation in either BRCA1 or BRCA2, your risk of developing breast cancer is significantly higher, with estimates suggesting up to an 80 per cent lifetime risk. Furthermore, these mutations are associated with a higher likelihood of developing breast cancer at a younger age.

Who should consider genetic testing?

Individuals with a strong family history of breast or ovarian cancer, particularly if multiple family members have been diagnosed at a young age, should consider genetic testing. This testing can provide valuable information for making informed decisions about screening, preventive measures and treatment options.

A positive test result can elicit fear and anxiety, but it can also empower you to take proactive steps in managing your health. This may involve more frequent screenings, preventive surgeries such as mastectomy or oophorectomy and lifestyle changes.

By embracing genetic testing and its potential implications, individuals can take proactive steps to mitigate their risk and potentially prevent breast cancer.
