Cancer Screening

Why should I consider doing hereditary cancer genetic testing?

The panel is appropriate for anyone interested in learning more about their hereditary cancer risks. Anyone who has a personal or family history of cancer may be at increased risk and should consider testing. Knowing your risk will help inform your healthcare choices.

While the chance of identifying a mutation may be lower without a known personal or family history of cancer, anyone can carry a change in a cancer gene. Individuals with Ashkenazi Jewish ancestry have a higher chance to carry a mutation in the BRCA1 and BRCA2 genes. 

Please note that without a personal or family history, insurance coverage is expected to be less likely.

Cancer Screening

If I have a mutation, will my children have it too?

Each child (regardless of gender) of a parent with a cancer gene mutation has a 50% chance of inheriting the mutation. Your genetic counselor can discuss the right time to test your children, as well as options for individuals who are planning to expand their families.

Cancer Screening

What happens if I test positive for cancer screening?

If you learn you have a mutation in a cancer gene, there are many ways to maintain your health and to impact the health of your family. A genetic counselor will walk you through your results and options for next steps.

Depending on the results, options may include:

• Lifestyle modifications (for example: reduced alcohol consumption)

• Increased and/or more frequent cancer screening (for example: mammogram, colonoscopy, prostate exam, skin cancer screening)

• Preventative risk-reducing surgeries (for example: mastectomy, removal of ovaries after childbearing)

• Options to avoid passing down mutations to your future children (for example: in-vitro fertilization (IVF) with pre-implantation genetic testing, adoption)

If you test positive for a mutation, you’ll be able to inform your relatives, who may also be at-risk.

Cancer Screening

Is all cancer hereditary?

No. There are many factors that contribute to a person’s risk for developing cancer, including lifestyle, diet, environmental exposures, and chance. But some cancers are related to specific genetic  changes that are inherited. For example, about 5-10% of breast cancers and about 20-25% of ovarian cancers are due to inherited genetic changes. A person may have an inherited change in a cancer gene even if cancer hasn’t occurred in their family. If you have specific questions related to your personal or family history of cancer, please contact a jscreen genetic counselor at genetic.counselor@jscreen.org

Cancer Screening

Should I consider testing if I have a current cancer diagnosis?

Yes. Genetic testing can help inform decisions about cancer treatments, including surgery, medications, clinical trials, and future surveillance. It can also be informative for other family members if a genetic risk is identified.

Note: please contact us HERE prior to registration if you have a current or past diagnosis of a hematological malignancy (blood cancer) or have received a stem cell or bone marrow transplant.
