Genetic Testing for Cancer: Balancing Benefits and Distress in Women's Health
"Understanding the Emotional Impact of BRCA1/2 Testing Without Pre-Test Counseling"
Genetic testing for cancer risk is becoming increasingly common, especially for women diagnosed with breast or ovarian cancer. These tests, particularly for BRCA1/2 genes, can reveal vital information that influences treatment decisions and preventive measures. However, receiving such information without adequate preparation can be emotionally challenging.
Traditionally, genetic testing involves pre-test counseling to help individuals understand the implications of the test results and cope with potential emotional distress. Yet, in many modern cancer clinics, BRCA1/2 testing is performed shortly after diagnosis, often without this crucial counseling step. This shift raises concerns about the psychological impact on women already grappling with a new cancer diagnosis.
A recent study published in Acta Oncologica sheds light on the experiences of women undergoing BRCA1/2 testing without pre-test genetic counseling. The research investigates the levels, course, and predictors of cancer-related distress in these women, providing valuable insights for healthcare professionals and individuals considering genetic testing.
What the Study Revealed About Distress and Genetic Testing
The study, led by Hildegunn Høberg-Vetti and colleagues, involved 309 women—259 with breast cancer and 50 with ovarian cancer—who underwent BRCA1/2 testing shortly after their diagnosis. These women did not receive pre-test genetic counseling. The researchers measured cancer-related distress using the Impact of Event Scale (IES) before and after genetic testing to assess intrusion and avoidance symptoms.
- Overall Distress Levels: The study found that the women experienced moderate levels of intrusion and avoidance symptoms both before and after genetic testing.
- Distress Reduction: There was a statistically significant decline in these symptoms over time, suggesting that women gradually adapted to the information and their situation.
- Predictors of Higher Distress: Certain factors were associated with higher levels of distress:
- Younger age
- Shorter time since diagnosis
- Lower levels of perceived social support
- Diagnosis of ovarian cancer
- Higher levels of decisional conflict regarding genetic testing
- Living without a partner
What This Means for Women and Healthcare Providers
The study underscores that women undergoing genetic testing shortly after a cancer diagnosis experience a moderate level of cancer-related distress. While this distress tends to decrease over time, certain factors can amplify it. Healthcare providers should be aware of these predictors—younger age, less social support, decisional conflict, and living without a partner—to identify women who may need additional support.
