How do I know if I am at high risk for breast cancer?

Some women have a higher than average risk of developing breast cancer. You may be at a higher risk if you have:

  • strong family history of breast cancer
  • certain gene mutations, such as the BRCA1 or BRCA2 mutation
  • a personal history of lobular carcinoma in situ (LCIS), ductal carcinoma in situ (DCIS), invasive breast cancer or atypical hyperplasia
  • dense breast tissue
  • received radiation therapy to the breast or chest

Talk to your doctor about your risk. If you are at higher than average risk, you may need a personal plan for testing. This may include:

  • mammography at a younger age
  • more frequent mammography
  • ultrasound or magnetic resonance imaging (MRI)
