Lung Cancer: Signs, Causes, and What You Need to Know

When we talk about lung cancer, a type of cancer that begins in the lungs and often spreads before symptoms appear. Also known as lung carcinoma, it’s the leading cause of cancer deaths in India, not because it’s rare, but because it’s often missed until it’s advanced. Most people don’t realize the early signs aren’t dramatic—they’re quiet. A cough that won’t go away, fatigue that doesn’t improve with rest, or weight loss without trying. These aren’t just "getting older"—they could be your body trying to tell you something serious is happening.

Smoking, the top cause of lung cancer in India, responsible for over 80% of cases. Also known as tobacco use, it’s not just cigarettes—hookah, bidis, and even secondhand smoke raise the risk. But here’s what few talk about: non-smokers get lung cancer too. Air pollution in cities like Delhi, indoor smoke from cooking fuels, and genetic factors play a big role. And once it spreads, cancer shutdown signs, the natural physical changes as the body slows down in late stages. Also known as end-stage cancer symptoms, they include loss of appetite, cold limbs, and changed breathing patterns. These aren’t failures of treatment—they’re part of the body’s process.

What’s missing from most conversations is how lung cancer doesn’t always look like the movies. No sudden collapse. No dramatic monologues. Just a slow, steady decline that families often mistake for old age or stress. The good news? If caught early, survival rates jump dramatically. Screening isn’t routine in India like it is in the U.S., but if you’re over 50, have smoked, or have a family history, asking for a low-dose CT scan could be life-changing. And while treatments like chemotherapy and immunotherapy are improving, access in rural areas remains uneven. That’s why understanding the signs matters more than ever.

Below, you’ll find real stories and clear facts about what lung cancer feels like—from the first warning signs to the quiet moments at the end. You’ll see how people in India are navigating treatment, managing side effects, and making sense of it all. No fluff. No jargon. Just what you need to know, whether you’re worried about yourself, a loved one, or just trying to understand the disease better.
