Why Genetic Screening Matters
Prostate cancer risk is influenced by genetics. If you have a family history of prostate cancer, are of African American descent, or have concerning PSA levels, genetic testing can help identify whether you carry mutations associated with increased risk. This information guides Dr. Libby in developing a personalized screening and prevention plan tailored to your actual risk.
What Is Prostate Cancer Genetic Screening?
Genetic screening involves a simple blood test that analyzes your DNA for mutations in genes associated with increased prostate cancer risk, such as BRCA1, BRCA2, and mismatch repair genes. The results help determine if you're at higher risk for more aggressive disease, which may warrant more frequent screening or earlier biopsy if PSA becomes elevated.
When Is Genetic Screening Recommended?
- Family history of prostate cancer — especially early-onset or aggressive cancer
- African American ancestry — higher genetic predisposition for prostate cancer
- Elevated PSA levels — understanding your genetic risk helps guide management
- Family history of breast cancer — BRCA mutations increase prostate cancer risk
- History of other cancers — especially those with genetic links
What to Expect
Before Testing
Dr. Libby will take a detailed family history and discuss your personal risk factors. You'll have the opportunity to ask questions about what the results mean and how they might affect your care. Genetic counseling is available to help you understand the testing and results.
The Test
A simple blood draw is all that's needed. The sample is sent to a specialized genetic laboratory that analyzes specific genes known to be associated with prostate cancer risk. Testing typically takes 2-4 weeks.
Understanding Results
Once results are available, Dr. Libby will discuss them in detail. A positive result means you carry a mutation associated with increased risk, which doesn't mean you have cancer but suggests more aggressive screening may be beneficial. Negative results provide reassurance but don't eliminate all risk, particularly if you have a strong family history.
Next Steps Based on Your Results
Your results guide personalized screening recommendations. Higher-risk patients may benefit from more frequent PSA testing, earlier consideration of biopsy if PSA rises, or MRI imaging to evaluate the prostate. Dr. Libby will explain your results and work with you to develop a plan that fits your preferences and risk profile.
