BreastGene, the breast cancer genetic test examines in detail the DNA code for 10 genes which are known to cause an increased risk of breast cancer. It is performed on a blood sample and if possible it is always more preferable to test a relative who has had breast cancer.
What is the difference between BreastGene and BRCA testing?
BRCA 1 /2 genetic testing looks at only the genes BRCA 1 and 2 while BreastGene looks at 8 other genes as well as BRCA 1 and 2.
Why would I want to have BRCA 1/2 testing rather than BreastGene?
There are several reasons why someone might decide to have BRCA 1/2 genetic testing rather than BreastGene:
- If a mutation has already been found in your family then you only need to have predictive BRCA testing to assess your risk.
- If you are Jewish you might decide to have the Jewish mutation test as your risk of a BRCA mutation may be higher than the risk of a different gene mutation.
- You might not want to know if you have a mutation in one of the other genes. In addition, BreastGene uses state of the art technology and is based on new information so there is a greater chance of finding something that science is currently unable to explain (a variant).
A genetic counsellor can give you more information about the genes included on the BreastGene panel and can help advise on the best test for you and your family.
Only 5-10% of breast cancers are hereditary but if there is a family history of breast cancer, this can be a big worry. Deciding to have a genetic test is a big decision for any man or woman and one that needs careful consideration. That’s why we offer genetic counsellors to assist you prior to any testing.
Our counsellors will provide you with all the information you need to make a decision and will help explain the process of genetic testing to you. Our counsellors will also be available once you have had your testing to discuss your results and options.
