The rate of lung cancer in people who have never smoked is significantly climbingWhile smoking is always seen as the highest risk factor for lung cancer, statistics say otherwise. According to studies, the rate of this deadly disease in people who have never smoked is significantly climbing. The American Cancer Society says as many as 20 per cent of people who die from lung cancer have never smoked or used any form of tobacco. 1 Also, research says more than 10-15 per cent of those affected with this cancer – caused by uncontrolled cell division in your lungs occurs in never-smokers, and that the numbers increase by 8 per cent every year. What type of lung cancer is detected in non-smokers? According to the Centers for Disease Control and Prevention, around 50-60 per cent of lung cancers found in non-smokers are adenocarcinomas, or cancer that begins in the cells that line the lung’s tiny air sacs and make mucous. Nearly 10-20 per cent are squamous cell carcinomas – a deadly form that starts in the thin, flat cells lining the inside of the lungs. Why are non-smokers getting lung cancer? Experts say many causes contribute to the phenomenon, a few of which include: Genetic mutations Doctors say those who do not smoke are more likely to have changes in their DNA, contributing largely to cancer development. These mutations, known as driver mutations, lead to otherwise healthy lung cells becoming cancerous, due to a natural glitch. According to experts, regular screening can help target a lot of these mutations and slow down the risk. Radon exposure Radon is a natural radioactive gas that trickles into homes from the ground. According to studies, radon gas exposure accounts for about 21,000 lung cancer deaths each year in the United States alone. Exposure to this gas is the second leading cause of lung cancer, owing to modern building construction practices that have increased its exposure. 2 Secondhand smoking Doctors say smoke from another person’s cigarette accounts for many lung cancer deaths yearly. Environmental pollution With rising pollution levels, exposure to air pollution, diesel exhaust, asbestos, and arsenic also lead to lung cancer in people who do not smoke. 3 Signs and symptoms of lung cancer Doctors say a persistent cough or pneumonia that keeps coming back after treatment can sometimes be an early sign of lung cancer. A few others may include: Repeated cough Shortness of breath or breathlessness Chest pain and discomfort Wheezing Coughing blood or hemoptysis Hoarseness of voice Weight loss Fatigue and tiredness Pain in shoulder Swelling in face and neck Small pupil and drooping eyelid Ways to prevent lung cancer Doctors say the only preventative measures are focused on reducing your risk, a few ways to do that are: Do not smoke or quit smoking if you do. Avoid secondhand smoke and other substances that can harm your lungs. Eat a healthy diet Get screened for lung cancer if you are at high risk.
