👉The National Comprehensive Cancer Network (NCCN) guidelines support genetic counseling for any woman diagnosed with early-onset breast cancer.
👉The current definition of early onset is age less than or equal to 50 year.
👉In addition, these guidelines support genetic counseling for any woman diagnosed with triple-negative breast cancer who is age 60 or younger.
👉This is because pathologic BRCA1 gene mutations are associated with basal-type triple-negative breast cancer.
👉The results of a genetic test would directly inform estimation of ipsilateral breast tumor recurrence risk with breast conservation, contralateral breast cancer risk, and risk for other cancers, such as ovarian cancer.
👉Genetic testing can be inexpensive depending on the provider.
