Genetic Counseling

What is Hereditary Breast Syndrome?

About 5-10 percent of breast cancers develop due to a mutation (a change in a gene) that has been passed down in the family. The two genes most commonly associated with inherited breast cancer are BRCA1 and BRCA2: Those who have a mutation in a BRCA gene have increased risks for breast cancer.

Our experts will assess your personal and family history to determine if testing for other genes associated with inherited breast cancers is needed.

Genetic Risk Assessment

The Clinical Cancer Genetics Program at Oregon Health & Science University Knight Cancer Institute is designed to evaluate and help you better understand your chance of having an inherited cancer syndrome. Our team includes American Board of Medical Genetics certified medical geneticists and American Board of Genetic Counseling certified genetic counselors.

At your genetics consultation, we will:

  • Review your personal and family history of cancer
  • Explain the hereditary basis of cancer
  • Talk to you about genetic testing options
  • Provide individualized risk assessment regarding the chance that your cancer developed due to an inherited mutation (for those who have been affected by cancer) or your chance to develop cancer based on your family history and the appropriate screening at your level of risk (for those who have a family history of cancer).

Is genetic risk assessment right for me?

Most families with a BRCA gene mutation have one or more of the following:

  • Women diagnosed with premenopausal breast cancer
  • Women diagnosed with ovarian cancer
  • Women diagnosed with 2 primary breast cancers or breast and ovarian cancer
  • Men diagnosed with breast cancer
  • Ashkenazi Jewish ancestry and breast or ovarian cancer at any age
  • A family member with a BRCA1 or BRCA2 mutation
