Triple-negative breast cancer risk factors


  • Age: Women under age 40 – 50 are more likely to get triple-negative breast cancer than women over age 60.
  • Race: Triple-negative breast cancer is more common among African American and Hispanic women than among Asian and non-Hispanic white women.


  • BRCA Mutation: BRCA1 and BRCA2 are genes that help repair damaged DNA. Mutations in BRCA1 and BRCA2 can be inherited from a family member. Women with the BRCA1 gene mutation have a higher risk of developing TNBC.

Understanding risk factors

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer. Not having risk factors doesn’t mean that you will not get cancer. If you think you may be at risk, you should discuss it with your doctor.

Advanced genomic testing

genomic tumor assessment

We use advanced genomic testing to examine a patient's tumor on a cellular level. This innovative tool can help us find what's driving the cancer's growth and offer patients more precise treatment.
