What is breast cancer?

Breast cancer is due to abnormal cells in the breast that grow out of control. Sometimes this can cause a lump in the breast tissue (though not all breast lumps are cancerous). Sometimes there are no symptoms, and cancer is found during a screening mammogram.

Could I have an increased risk for breast cancer?

Risk factors for inherited breast cancer include:

  • Family history of young breast cancer diagnoses (under age 50)
  • Multiple family members with breast cancer
  • Multiple primary breast cancer diagnoses
  • A family history of pancreatic, ovarian or prostate cancer (especially if it is the rare, more aggressive type, with a Gleason score of 7+)
  • Families with Ashkenazi Jewish ancestry (eastern European)
  • There is a known gene mutation in your family
