For individuals with mutations in their BRCA genes, this process does not work as well as intended, leading to more DNA mutations than people with normal BRCA genes and hence a higher risk of cancer. "We need to start thinking about whether its time to start screening people using genetic testing. The Geisinger study participants were provided with expert advice and prepared for what they might find after undergoing the genetic testing. Those who were identified as having BRCA mutations were suitably supported with their medical care and also getting family members screened. It's essential that people know what the risks and benefits of genetic testing are.
