To test or not to test

When deciding to have the BRCA gene test. There are many factors to weigh — some scientific, some emotional — when deciding whether or not to get a genetic test. Ultimately, the decision is a personal one, and no one can tell you with absolute certainty which choice is right for you. What genetics professionals and physicians can do is walk you through the process of testing and make you aware of the relevant issues involved so that you can make the best choice for yourself and your family.

A few points to remember:

Firstly, it's important to understand that breast cancer is a common type of cancer. Therefore, it is not uncommon to have a family history of breast cancer. It is only some people who are at higher-than-average risk due to an inherited gene mutation in the family.

It's also important to be aware that only about 5% of all breast cancers are caused by the inherited gene mutations for which testing is currently available.

A 'strong family history' is one in which breast and/or ovarian cancer occur over several generations, often with young women affected. 

The gene mutations known to increase breast cancer risk can be passed on by both the mother and the father, so it's important to ask about family history on both sides.

See if you are eligible for genetic testing, if you are eligible, contact your local GP or family cancer centre and they will advise you how to progress from there.

If you are considering any kind of genetic testing it is important to be fully informed in every aspect of the test.
