In some cases, people who test positive for genetic testing can receive preventive treatments.
For example, people who test positive for the breast cancer genes BRCA1 and BRCA2 can
have a preventive mastectomy (breast removal surgery) before they develop the disease. In
other cases, no preventive treatments are available, but frequent monitoring can help detect a
disease earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to address when
he or she has a patient who wants to prematurely treat a genetic disease? Do you think
genetic testing should be part of normal preventive healthcare? Why or why not?
