What are the risk factors of lung cancer?

Apart from smoking, exposure to heavy air pollution and radon gas are massive risk factors. Keeping your cardiovascular endurance high through regular exercise is great, but you must protect your lungs by wearing masks in highly polluted zones and avoiding any form of tobacco.

My uncle never smoked a single cigarette in his life but still got diagnosed because of passive smoking at his old workplace. Second-hand smoke and working in dusty industrial areas are huge risk factors that people don't take seriously enough. Protect your lungs, guys.

Please don't believe any online posts claiming that certain breathing exercises or herbal teas can reverse the damage of smoking. Tobacco use, asbestos exposure, and genetics are the primary risk factors for lung cancer. If you have a chronic cough, consult a pulmonologist immediately.

Look, if you have a persistent cough that doesn't go away in three weeks, or if you cough up blood, stop looking for answers online. These can be warning signs. Smoking, family history, and chemical exposure are the main risk factors, so get checked by a specialist.

Our family physician highlighted that genetic mutations and exposure to radon gas in closed basements are significant non-smoking risk factors. If you have been a heavy smoker for over 20 years, they highly recommend annual screenings once you cross 50.

Having seen many discussions on this forum, smoking is undeniably the leading risk factor, responsible for the vast majority of cases. However, family history and exposure to industrial chemicals like arsenic or coal products are also critical. Regular health screenings are vital as we age.

When my father was diagnosed, the oncologists at the hospital explained that previous lung diseases like TB also increase the risk. Every case is unique, and you should ask your doctor about screening options like low-dose CT scans if you have a history of heavy smoking.

We moved out of a highly industrial zone because my son's asthma was worsening, and the doctors warned us about the long-term cancer risks of chemical fumes. Air pollution and household radon are serious risk factors for young lungs. Make sure your home is well-ventilated.

Let's be direct—living in highly polluted metro cities makes us all vulnerable, but smoking remains the absolute number one risk factor. If you smoke, you need to quit today. There are no excuses or shortcuts when it comes to your lung health.
