At-risk families can take blood tests to screen for mutations in the BRCA
genes. However, genetic testing is done only when definitely indicated by a
personal or a strong family history. Genetic testing may also be used to
determine if a woman who has already been diagnosed with breast cancer is at an
increased risk for a second breast cancer or ovarian cancer.
For some women, the benefits of genetic testing
including the ability to make medical and lifestyle decisions while reducing the
anxiety of not knowing their genetic background. Another benefit is the ability
to make a proactive decision regarding prophylactic surgery. In addition, many
women are able to participate in medical research that may in the long run
decrease the risk of death from breast cancer.
Here are some questions to consider when thinking about genetic testing:
Am I prepared to cope with the result? Are my family members, including my
children and my spouse?
What are my goals for testing?
How would I use my test results? What will I do differently if the results
are positive, or if they are negative?
Who will I share my results with?
Would a positive test result change relationships with my family?
