Breast Cancer Genetics

  1. Ataxia Telangiectasia (A-T)

    The risk for breast cancer may be increased for women who carry the A-T gene. Ataxia telangiectasia is a rare childhood disease that affects the nervous system and other body systems.

  2. Cowden Syndrome

    The risk for breast cancer, gastrointestinal cancers, and thyroid cancer is increased with Cowden syndrome, a rare genetic disorder.

  3. Hereditary Breast Ovarian Cancer Syndrome (BRCA1/BRCA2)

    A woman with this syndrome may develop breast cancer before age 50 and is at higher risk for developing cancer in both breasts or in both the breasts and ovaries.

  4. Li-Fraumeni Syndrome

    Li-Fraumeni syndrome raises the risk for breast cancer and many other types of cancer.

  5. Peutz-Jeghers Syndrome

    People with this syndrome have dark moles around the mouth, nose, and eyes, as well as multiple polyps in the intestines.
