Lung cancer is commonly associated with smoking, but did you know that non-smokers can also develop lung cancer? In fact, according to the American Cancer Society, approximately 20% of lung cancer cases occur in non-smokers. In this guide, we’ll explore everything you need to know about lung cancer in non-smokers, including its causes, symptoms, diagnosis, and treatment options.
Causes of Lung Cancer in Non-Smokers

While smoking is the primary cause of lung cancer, non-smokers can also develop it due to various factors. These factors include exposure to radon, a colorless and odorless gas found in soil and rocks that can seep into homes and buildings, increasing the risk of lung cancer. Secondhand smoke, which is smoke exhaled by smokers or given off by burning tobacco products, can also increase the risk in non-smokers. Other causes of lung cancer in non-smokers include prolonged exposure to air pollution, such as smog and particulate matter, and occupational hazards such as asbestos and diesel exhaust in certain workplaces like mines, factories, and construction sites.
Symptoms of Lung Cancer in Non-Smokers

The symptoms of lung cancer in non-smokers are similar to those in smokers and may include coughing, shortness of breath, chest pain, fatigue, unexplained weight loss, and coughing up blood. Additionally, non-smokers with lung cancer may also experience hoarseness and difficulty swallowing. If you experience any of these symptoms, it’s important to see your doctor right away.
Diagnosis of Lung Cancer in Non-Smokers

If your doctor suspects that you have lung cancer, they will likely order a series of tests, including imaging tests such as CT scans and X-rays, and a biopsy, which involves taking a small sample of tissue from the lung for examination. These tests will help determine the stage and type of lung cancer you have.
Treatment Options for Lung Cancer in Non-Smokers

The treatment options for lung cancer in non-smokers are similar to those in smokers and may include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Depending on the stage and type of lung cancer, your doctor may recommend a combination of these treatments. Your doctor will work with you to determine the best treatment plan based on your individual needs.
Prevention of Lung Cancer in Non-Smokers
While there is no sure way to prevent lung cancer in non-smokers, there are steps you can take to reduce your risk. These include avoiding exposure to secondhand smoke, which is especially important if you live with a smoker or spend time in places where people smoke. Testing your home for radon and taking steps to reduce its levels, such as sealing cracks in floors and walls, can also help lower your risk of lung cancer. Additionally, reducing your exposure to air pollution by staying indoors during times of high pollution and wearing protective equipment, such as masks, in hazardous work environments can also be helpful.
Conclusion
Although lung cancer in non-smokers is less common than in smokers, it’s important to be aware of the risks and symptoms. If you experience any symptoms of lung cancer, it’s important to see your doctor right away. Early detection and treatment can greatly improve your chances of a successful outcome.
