Patient experiences with genetic testing

Expert Guidelines

The National Comprehensive Cancer Network has guidelines on who should undergo genetic counseling and testing. If you have been diagnosed with breast cancer, you should speak with a genetics expert about genetic testing if any of the following apply to you:     

• You have a blood relative who has tested positive for an inherited mutation 
• You have any of the following:  
  • Breast cancer at age 50 or younger  
  • Male breast cancer at any age
  • Ovarian cancer at any age  
  • Triple-negative breast cancer at any age 
  • Two separate breast cancer diagnoses
  • Eastern European Jewish ancestry and breast cancer at any age 
  • Metastatic breast cancer 
  • Testing of your tumor shows a mutation in a gene that is associated with hereditary cancer
  • HER2-negative breast cancer and high risk for recurrence
  • Lobular breast cancer and a family history of diffuse gastric cancer

OR 

• You have one or more close family members who have had:  
  • Young-onset or rare cancers 
  • Breast cancer at age 50 or younger
  • Triple-negative breast cancer
  • Male breast cancer, ovarian cancer, pancreatic cancer, or metastatic prostate cancer at any age
  • Two separate cancer diagnoses 
  • Prostate cancer at age 55 or younger or metastatic prostate cancer 

The American Society of Breast Cancer Surgeons (ASBrS) released guidelines in 2019 that recommend all women diagnosed with breast cancer have access to genetic testing for inherited mutations in breast cancer genes. 

If you are uncertain whether you meet the guidelines above and you are interested in or considering genetic testing, you should speak with a cancer genetics expert. 

 

Questions To Ask Your Health Care Provider

• Should I have genetic testing? 
• How can I tell if cancer runs in my family?
• I had breast cancer before age 50 and I have a strong family history of cancer, but I tested negative for a BRCA mutation. Should I consider expanded panel testing?
• Can you refer me to a genetic counselor?

Open Clinical Trials

Below are clinical trials that include genetic counseling and testing.

• NCT02665195: Prospective Registry Of MultiPlex Testing (PROMPT). PROMPT is an online research registry. The goal of PROMPT is to help researchers to better understand the risks that are linked to mutations in less well-studied genes. 
• NCT04245176: Genetic Testing for All Breast Cancer Patients (GET FACTS). This study looks at the impact of a novel genetic counseling method on surgical decisions in people with newly diagnosed breast cancer. This study involves genetic counseling about contralateral breast cancer risk. 
• NCT02620852: WISDOM Study: Women Informed to Screen Depending on Measures of Risk offers women age 40-74 the opportunity to undergo risk assessment and genetic testing in order to determine the best breast screening options based on their situation.  
• Enhancing Genetic Risk Assessment in Underserved Blacks and Latinas at Risk of Hereditary Breast Cancer. This study will test how well educational materials increase the use of knowledge about hereditary cancer risk.
• NCT04476654: Improving Uptake of Genetic Cancer Risk Assessment in African American Women-Video. This study looks at the usefulness of intervention with a culturally-tailored video to improve uptake of genetic counseling in Black women who are at increased risk of HBOC.
