The leading oncologists in Kolkata have seen the devastating effects of lung cancer on patients and their families. Lung cancer is the most widespread cancer throughout the globe, and it is responsible for more deaths than any other type of cancer. There is no surefire way to prevent lung cancer. However, understanding the risk factors for the disease can help you take steps to reduce your risk and catch the disease early on if it does take root.

The Widely Prevalent Risk Factors for Lung Cancer

The eminent lung cancer doctors in Kolkata have identified the most widespread risk factors for lung cancer. A better awareness about them will not only let you take preventive measures but also help you decide when to resort to screenings. Below we take a closer glimpse at the risk factors:


The most notorious risk factor for lung cancer is smoking. Smoking tobacco damages the DNA in your lungs and other organs, leading to mutations that can turn healthy cells into cancerous ones. Second-hand smoke exposure is also a risk factor for lung cancer. People who live or work with smokers are exposed to many of the same harmful chemicals that smokers inhale. The act of passive smoking increases your risk of lung cancer by 20-30%.

Prolonged Exposure to Radon Gas

Prolonged radon exposure is the second primary cause of lung cancer. Radon, a naturally occurring radioactive gas, can infiltrate homes and buildings through cracks in the foundation. Breathing in radon gas can damage the DNA in your lungs and increase your risk of lung cancer. Testing your home for radon and reducing exposure can help lower your risk of developing lung cancer.

Exposure to Hazardous Substances

Exposure to certain chemicals and substances at work, such as asbestos, arsenic, and diesel exhaust, can increase your risk of lung cancer. If you work in an industry where you may be exposed to these substances, it is essential to take all the necessary precautions to protect yourself.

Prior Family History of Cancer

Best cancer doctors in Kolkata believe genetics and family history can also play a role in your risk of developing lung cancer. If you have a prior family history of lung cancer or a genetic mutation that predisposes you to the disease, your risk of developing lung cancer is higher.

Hence, there are a few precautionary measures you can take to prevent falling into the clutches of lung cancer. Beginning with quitting smoking and testing your home for radon gas, these precautionary measures also include minimising substance exposure at the workplace and awareness of your immediate family history. If you’ve been diagnosed with lung cancer, it is important to know that there is hope. Lung cancer treatment has come a long way in recent years, and new therapies are constantly being developed. The best oncologists in Kolkata can help you decide what combination of treatments will suit you best.
