BRCA Mutations in Indian Women: What We Know So Far

Mentioning the term BRCA mutation can be baffling. Indian women need to know more about these genetic changes because they pose a great risk of hereditary breast and ovarian cancer. This is an informative and straightforward explanation of what is known about BRCA mutations in India.

BRCA Mutations in the Indian population.

The BRCA variant spectrum in India is diverse and differs from Western populations is more concise. It has been shown that a significant number of mutations are founder mutations, i.e., mutations that are specific to particular communities or geographical regions and are transmitted across generations. This renders genetic research on the Indian subcontinent important since a test tailored to Western populations may fail to identify all local deviations.

Who needs to be tested for BRCA mutations?

Genetic testing in India is most advisable when you have:

• Good family history of breast or ovarian cancer.
• Diagnosed with breast cancer before age 40.
• Several family members on one side have breast or ovarian cancer.
• A male family member who has breast cancer.
• When you fall into either of these classifications, it is important to talk to a genetic counselor first.

Impact of BRCA mutations on therapy.

A positive BRCA test is not the end; it’s a starting point. Knowing your status helps you plan your treatment and take better care of your health. An example is when a patient with early-stage breast cancer and a BRCA mutation chooses a double mastectomy to greatly reduce the risk of cancer recurrence or prevent other breast cancer. It also provides access to specific treatment options, such as PARP inhibitors, which specifically target cancer cells with BRCA deficiencies.

The genetic testing environment in India is improving rapidly. Although cost and awareness remain major obstacles, several labs now provide smaller and more comprehensive BRCA panels at lower prices. It is becoming more and more available in the big cities, but availability in smaller towns continues to increase.

Family counseling and risk management.

A positive BRCA test result can affect the entire family. Genetic counseling is essential to help you and your relatives understand the implications of the test and the possibility of inheriting the mutation. Proactive risk management can help reduce the likelihood of developing cancer and may include:

• Increased screenings: Starting mammograms and breast MRIs earlier than usual.
• Preventive surgery: Some women may choose to remove their ovaries or breasts before cancer develops.
• Lifestyle changes: Maintaining a healthy weight, limiting alcohol intake, and adopting other healthy habits.

Understanding BRCA mutations, getting tested, and taking proactive steps can empower women and their families to manage risk and make informed health decisions
