Myriad Genetics has revolutionized the field of genetic testing by offering comprehensive screening tools for hereditary cancer risk. Their tests provide critical insights to help individuals and families make informed medical decisions.
Key hereditary cancer tests offered by Myriad include:
-
MyRisk® Hereditary Cancer Test: Analyzes 48 genes linked to hereditary cancers, including breast, ovarian, colorectal, pancreatic, and prostate cancers.
-
BRACAnalysis®: Detects mutations in BRCA1 and BRCA2 genes, which significantly increase the risk of breast and ovarian cancer.
-
Colaris®: Identifies Lynch syndrome, a hereditary condition that raises the likelihood of colorectal and endometrial cancer.
-
RiskScore®: Provides an individualized breast cancer risk assessment for women with or without a BRCA mutation.
Who Should Consider Genetic Testing?
Genetic testing for hereditary cancer may be recommended for individuals who:
-
Have a strong family history of cancer, particularly diagnosed at a young age.
-
Have multiple relatives with the same or related types of cancer.
-
Have a known genetic mutation in the family, such as BRCA1 or BRCA2.
-
Have been diagnosed with a rare or early-onset cancer.
-
Want to take a proactive approach to cancer prevention and early detection.
Benefits of Hereditary Cancer Screenings with Myriad Genetics
-
Early Detection: Identifying genetic risks enables earlier and more frequent screenings, such as mammograms or colonoscopies.
-
Targeted Prevention Strategies: High-risk individuals can adopt preventive measures like lifestyle modifications, medications, or risk-reducing surgery.
-
Family Health Awareness: Knowing your genetic risk can help relatives determine whether they should also consider testing.
-
Personalized Treatment Plans: Genetic insights can guide tailored cancer treatments and improve patient outcomes.
How Myriad Genetic Testing Works
-
Consultation with a Healthcare Provider: A doctor or genetic counselor assesses family history and risk factors.
-
Sample Collection: A simple blood or saliva sample is taken for analysis.
-
DNA Analysis: The sample is sent to Myriad’s lab, where advanced technology identifies mutations associated with hereditary cancer.
-
Results Interpretation: A healthcare provider explains the results and discusses next steps for prevention, monitoring, or treatment.
Understanding Your Test Results
-
Positive Result: A genetic mutation was found, indicating an increased cancer risk. Preventive measures may be recommended.
-
Negative Result: No known hereditary mutations were detected, though lifestyle and environmental factors still play a role in cancer risk.
-
Variant of Uncertain Significance (VUS): A genetic variation was found, but its impact on cancer risk is unclear. Further research may be needed.
Taking Action After Screening
If a hereditary cancer risk is identified, options may include:
-
More Frequent Screenings: Regular check-ups and imaging tests for early cancer detection.
-
Preventative Medications: Certain drugs may help lower cancer risk in high-risk individuals.
-
Lifestyle Adjustments: Maintaining a healthy diet, regular exercise, and avoiding known carcinogens.
-
Risk-Reducing Surgery: In some cases, preventive surgery (such as mastectomy or hysterectomy) may be considered.
The Future of Genetic Testing and Cancer Prevention
As genetic research advances, companies like Myriad Genetics continue to refine and expand testing capabilities. With more personalized and precise screening tools, individuals at risk for hereditary cancers can make empowered healthcare decisions that lead to better outcomes.
