Smoking isn’t the only risk factor: busting myths around lung cancer
The gap between what people believe about lung cancer and what medicine can actually offer has never been wider
A lung cancer diagnosis can shatter conversations and plans. Families often become silent, assuming the outcome is predetermined. However, early detection can lead to meaningful and even curative treatment. In India, most patients are diagnosed at advanced stages, limiting treatment options. Late detection is the issue, not the disease itself.
Lung cancer found early is genuinely treatable through surgery with curative intent. The key factor is when the disease is diagnosed. Smoking is the most recognized risk factor, but other factors also play a role. Prolonged exposure to indoor cooking fuel smoke, second-hand smoke, and occupational carcinogens increases risk. Registry data shows a rise in cases among women and non-smokers.
Adenocarcinoma, the most common subtype now, often carries specific genetic mutations responsive to targeted treatment. Persistent respiratory symptoms, even in non-smokers, warrant attention. These include a chronic cough, recurring chest infections, unexplained weight loss, and worsening breathlessness. Early signs like coughing up blood, a persistent hoarse voice, or worsening chest pain should prompt medical evaluation.
Attributing these symptoms to weather or aging is common, but it leads to missed early diagnoses. Early diagnosis and surgical removal can make lung cancer treatable. Low-dose CT scans can detect small lung nodules before symptoms appear, offering a window for treatment. In high-risk individuals, screening with low-dose CT scans is cost-effective in India.
Molecular testing can identify specific tumor mutations, leading to targeted therapies and immunotherapy options. Patients with a long smoking history, a family history of lung cancer, or occupational exposure should discuss their risk with a doctor, even without symptoms. Early detection is crucial, as time is the most significant factor limiting treatment options.
Advances in treatment have improved outcomes for many patients, but early diagnosis remains paramount.
