For patients facing stage 4 lung cancer or those with a strong family history of cancer, genetic testing can offer clarity, guidance, and hope. About 10% of cancers are hereditary, meaning they are driven by inherited gene mutations that can be passed through families. Testing for these mutations, such as BRCA1, BRCA2, and others linked to lung or related cancers, helps doctors understand a patient’s personal cancer risk and may also guide treatment choices—especially for targeted therapies.
Importantly, having a gene mutation doesn’t mean you’ll definitely get cancer, but it does raise your risk. If you already have cancer, genetic testing can sometimes influence treatment decisions, like choosing one type of chemotherapy or surgery over another. For those with a family history, testing can alert relatives to start earlier cancer screenings or preventive measures. Bringing a detailed family history to your genetic counseling appointment can be a valuable first step.
Knowing your genetic risk empowers you to take proactive steps—whether that’s enrolling in clinical trials, pursuing early screening, or helping your children understand their potential risks. While we can’t change our genes, we can change how we respond to what they tell us. (Source: Mayo Clinic)
