RATIONALE: Breast cancer clinicians frequently employ genetic testing with breast cancer patients. It is unclear what psychological consequences have resulted from the knowledge gained from these tests. A literature review reveals that results are contradictory in terms of determining stress levels related to test results. This is due to different study methodologies. The Medical College of Wisconsin Cancer Center researchers will generate more definitive answers through a prospective study that will establish baseline stress levels, evaluate pre- and post- test stress levels at multiple time points, focus on the changes in stress levels for the different resulting subgroups. Evaluating the impact of genetic testing on stress levels will help health care professionals to better understand the consequences of genetic testing, and thus, provide better care for patients both medically and psychologically through potential interventions to decrease stress.
