Breast cancer is one of the most common cancers affecting women worldwide. In India, the incidence is rising, with an estimated 2.13 million new cases in 2021 and projections of 2.4 million by 2025. While most cases are sporadic, about 5-10% are hereditary, driven by mutations in genes like BRCA1 and BRCA2. Understanding your genetic risk can empower you to take proactive steps for early detection and prevention.
At DNA Labs India, we offer comprehensive BRCA genetic testing using advanced Next-Generation Sequencing (NGS) technology. Our ISO 9001 certified lab ensures accurate and reliable results.
What Are BRCA1 and BRCA2 Genes?
BRCA1 and BRCA2 are tumor suppressor genes that produce proteins responsible for repairing damaged DNA. When these genes contain mutations, the repair mechanism is compromised, leading to an increased risk of breast and ovarian cancers. These mutations are inherited in an autosomal dominant pattern, meaning a 50% chance of passing the mutation to offspring.
Key Functions:
- DNA Repair: Fixing double-strand breaks
- Cell Cycle Regulation: Controlling cell division
Who Should Consider BRCA Testing?
Genetic testing is recommended for individuals with a personal or family history suggestive of hereditary breast and ovarian cancer syndrome. The following criteria increase the likelihood of carrying a BRCA mutation:
- Diagnosed with breast cancer at age 50 or younger
- Triple-negative breast cancer diagnosed at any age
- Two or more primary breast cancers
- Male breast cancer
- Ovarian cancer at any age
- Ashkenazi Jewish ancestry
- Known BRCA mutation in a family member
What Does the BRCA Test Involve?
The test is a simple blood or saliva sample. No fasting is required. The sample is sent to our ISO 9001 certified lab, where DNA is extracted and analyzed using Next-Generation Sequencing (NGS) to detect mutations in both BRCA1 and BRCA2 genes. Results are typically available within 10-14 business days.
Understanding Your Results
Results are reported as:
- Positive: A mutation is present, increasing cancer risk. Preventive measures and enhanced surveillance are recommended.
- Negative: No mutation detected. This does not eliminate risk entirely but indicates no hereditary mutation in these genes.
- Variant of Uncertain Significance (VUS): A genetic change with unclear clinical impact. Further research and family testing may be needed.
If you test positive, targeted therapies like PARP inhibitors may be an option for treatment.
