Genetic Testing for BRCA1 & BRCA2 in India: A Guide to Detection, Prevention & Care

Introduction

Breast cancer is now the most common cancer affecting women in India, with recent government data showing a steady rise in cases—from approximately 2.13 lakh in 2021 to nearly 2.4 lakh in 2025 . For many families, a diagnosis feels like it comes without warning. But what if you could look into the future to understand your risk?

If you have watched a mother, sister, or aunt battle cancer, you may have wondered, “Will I be next?” This fear is valid, but it doesn’t have to leave you feeling helpless. While most breast cancers are not inherited, a significant portion is linked to specific gene mutations passed down through families—namely in the BRCA1 and BRCA2 genes.

This guide is designed to help you understand the basics of breast cancer, the role of genetics, and how a simple breast cancer test like the one offered at DNA Labs India can empower you with the knowledge to take control of your health journey.


What is Breast Cancer? Understanding the Basics

To understand genetics, we must first understand the disease itself. So, what is breast cancer? In simple terms, our bodies are made up of billions of cells that grow and divide in an orderly manner. Sometimes, this process goes wrong.

Breast cancer causes begin when the DNA in a breast cell mutates (changes), causing the cell to grow uncontrollably. These rogue cells multiply, forming a lump or mass. While the exact causes vary, they can range from lifestyle factors to inherited genes.

It is crucial to recognize the warning signs early. Common cancer symptoms specific to the breast include changes in texture, shape, or the presence of a lump. By increasing breast cancer awareness, we empower ourselves to notice these changes immediately.


The Role of Genetics: Understanding BRCA1 and BRCA2

Why do some families seem more prone to cancer than others? This usually comes down to the difference between “sporadic” and “hereditary” cancer.

  • Sporadic Cancer: This occurs by chance due to aging or lifestyle. It usually appears in one family member without a strong pattern.
  • Hereditary Cancer: This is caused by a genetic mutation passed from parent to child.

What are BRCA1 and BRCA2? They are not “bad” genes; in fact, they are tumor suppressor genes. Think of them as the “proofreaders” of your cells. They fix everyday damage to your DNA. However, when a person inherits a mutation in BRCA1 or BRCA2, these proofreaders stop working. This significantly increases the risk of developing breast cancer cause and ovarian cancer.

Who is at Risk? (Breast Cancer Age & Family History)

Anyone can develop breast cancer, but certain factors increase the likelihood that it is hereditary.

  • Breast Cancer Age: While risk increases with age (especially after 50), hereditary cancers often strike younger. If you have a family member diagnosed before 50, it is a red flag .
  • Family Tree Red Flags:
    • Multiple relatives on the same side of the family with breast, ovarian, or prostate cancer.
    • A male relative with breast cancer symptoms or diagnosis (male breast cancer is rare and often genetic).
    • Anyone in the family who had cancer in both breasts.
    • Ashkenazi Jewish heritage, which has a higher carrier rate for BRCA mutations .

Signs & Symptoms: When to Seek Help

Being “breast aware” means knowing what is normal for you. Many women experience breast pain or changes in their monthly cycle, which is usually hormonal. However, if you notice any of the following symptoms of breast cancer, you must consult a doctor immediately:

  • Breast Lump: A hard, painless lump or thickening in the breast or underarm (armpit). Remember, not all lumps are cancerous, but they must be checked .
  • Changes in Appearance: Dimpling of the skin (like the peel of an orange), redness, or swelling.
  • Nipple Changes: A nipple that turns inward (retraction) or discharge (especially if bloody).
  • Pain in Breast: Persistent, unexplained pain in breast or a specific spot that does not go away. While breast pain is rarely the first sign of cancer, it is your body’s way of asking for attention .

The Diagnostic Pathway: From Screening to Genetic Testing

If you notice a lump or have breast cancer symptoms, your doctor will first recommend screening:

  1. Imaging: A mammogram or ultrasound to visualize the lump.
  2. Biopsy: If the lump looks suspicious, a tissue sample is taken to confirm if it is cancer.

However, if cancer runs in your family, the next step is a breast cancer test of a different kind—a genetic test. This test does not diagnose current cancer; it looks for the inherited mutation that increases the risk of developing cancer in the future.

At DNA Labs India, our BRCA test is simple. It requires just a small blood sample or a cheek swab (saliva). The sample is analyzed in our state-of-the-art lab to look for mutations in your BRCA1 and BRCA2 genes.

Understanding Your Results & The Path to Prevention

Your genetic test report from DNA Labs India will typically show one of three results:

  • Positive: A harmful mutation was found. This does not mean you have cancer. It means your risk is higher. You can work with your doctor on a plan which may include:
    • Enhanced Screening: Starting mammograms earlier or getting MRIs.
    • Medications: Drugs that may reduce risk (chemoprevention).
    • Prophylactic Surgery: Some high-risk women choose to undergo breast cancer surgery (mastectomy) to remove the breasts before cancer develops. This is a deeply personal decision to discuss with an oncologist.
  • Negative: No mutation was found. Your risk is likely the same as the general population.
  • Variant of Uncertain Significance (VUS): A change was found, but scientists don’t yet know if it increases risk. This result is not uncommon and is usually reclassified over time as more data becomes available.

If you are diagnosed with cancer, knowing your BRCA status can also guide breast cancer treatment. For example, specific targeted therapies (PARP inhibitors) work exceptionally well in BRCA-positive cancers .


Frequently Asked Questions (FAQs)

What is the right breast cancer age to start genetic testing?

Genetic testing is generally recommended for adults (18+), especially if there is a strong family history of early-onset cancer. Unlike a mammogram, which starts at a certain age, genetic testing is driven by family history, not age .

Is the BRCA test painful?

No. It is a simple, non-invasive process requiring only a small blood sample or a cheek swab. There is no pain involved.

If I have a breast lump, should I get a genetic test first?

No. A lump requires immediate clinical evaluation. You need a mammogram or biopsy to diagnose the lump now. Genetic testing helps determine the cause and your future risk, but a lump requires diagnostic testing first .

How long does it take to get results from DNA Labs India?

Results for BRCA1 & BRCA2 genetic sequencing are typically available within 10-14 working days.

Does health insurance cover genetic testing for breast cancer in India?

Coverage varies by provider and policy. Some insurance companies are beginning to cover testing for individuals with a strong family history. DNA Labs India can provide a detailed invoice and all necessary documentation to assist with your claim process.

Conclusion: Take Control of Your Health Today
