Introduction
Breast cancer is the most common cancer among Indian women, with an estimated 2.4 million new cases projected by 2025. While most cases are sporadic, a significant proportion—about 5-10%—are hereditary, driven by mutations in high-penetrance genes such as BRCA1 and BRCA2. Understanding your genetic risk is crucial for early detection, prevention, and targeted treatment.
At DNA Labs India, an ISO 9001 certified lab, we offer comprehensive BRCA genetic testing using advanced Next-Generation Sequencing (NGS) technology to provide accurate and actionable results.
What Are BRCA1 and BRCA2 Genes?
BRCA1 and BRCA2 are tumor suppressor genes that play a critical role in repairing damaged DNA. They act as "proofreaders" of the genome, ensuring that errors during cell division are corrected. When these genes carry harmful mutations, the body's ability to repair DNA is compromised, leading to an increased risk of breast, ovarian, and other cancers.
Mutations in BRCA1 and BRCA2 are inherited in an autosomal dominant pattern, meaning a single copy of the mutated gene from either parent can increase cancer risk.
Hereditary vs. Sporadic Cancer
Cancer can be classified based on its origin:
- Sporadic Cancer: Occurs due to acquired mutations over a lifetime, often linked to environmental factors or aging. No family history is typically present.
- Hereditary Cancer: Caused by inherited genetic mutations, leading to a higher lifetime risk and often earlier onset.
BRCA1 and BRCA2 mutations are the most common cause of hereditary breast and ovarian cancer syndrome.
Who Should Get BRCA Genetic Testing?
Genetic testing is recommended for individuals with a personal or family history suggestive of hereditary cancer. The following criteria are based on NCCN guidelines:
- Diagnosed with breast cancer at age 50 or younger.
- Triple-negative breast cancer diagnosed at age 60 or younger.
- Two or more primary breast cancers.
- Known BRCA mutation in a family member.
- Male breast cancer at any age.
- Ovarian cancer, fallopian tube cancer, or primary peritoneal cancer.
- Ashkenazi Jewish ancestry with a personal or family history of breast or ovarian cancer.
Symptoms of Breast Cancer
Early detection saves lives. Be aware of the following symptoms and consult a physician if you notice any changes:
| Symptom | Description |
|---|---|
| Lump or thickening | A new lump in the breast or underarm area |
| Nipple changes | Nipple inversion, discharge, or scaling |
| Skin changes | Dimpling, redness, or puckering of breast skin |
| Pain | Persistent breast pain not related to menstrual cycle |
Diagnostic Methods
If symptoms are present, imaging and biopsy are the first steps:
- Imaging: Mammogram and ultrasound to identify suspicious areas.
- Biopsy: Tissue sampling for histopathological examination.
For hereditary risk assessment, genetic testing is essential. DNA Labs India offers BRCA1 and BRCA2 full gene sequencing using NGS, which detects mutations with high accuracy. The test requires only a simple cheek swab or blood sample.

Understanding Test Results
Your BRCA test result will fall into one of three categories:
- Positive: A harmful mutation was found. This increases your cancer risk and informs preventive and treatment strategies.
- Negative: No mutation detected. This does not eliminate cancer risk entirely, but reduces the likelihood of hereditary BRCA-related cancer.
- Variant of Uncertain Significance (VUS): A genetic change was found, but its impact is unknown. Further research and family studies may be needed.
If you test positive, your healthcare provider may recommend enhanced surveillance, risk-reducing surgeries, or targeted therapies such as PARP inhibitors, which are effective in BRCA-positive cancers.
Frequently Asked Questions (FAQ)
- Who should consider genetic testing? Individuals with a personal or family history of breast/ovarian cancer, especially at a young age.
- Is the test painful? No, a simple cheek swab or blood draw is all that is required.
- Can I get tested without symptoms? Yes, genetic testing is recommended for high-risk individuals even without symptoms.
- How long does it take to get results? Typically 10-14 business days.
- Will my insurance cover the test? Coverage varies; consult your provider. DNA Labs India offers affordable pricing.
