It usually grows and spreads more slowly than small cell lung cancer. There are three forms of NSCLC: Adenocarcinomas are often found in an outer area of the lung. Squamous cell carcinomas are usually found in the center of the lung by an air tube (bronchus). Large cell carcinomas can occur in any part of the lung. They tend to grow and spread faster than the other two types. Causes, incidence, and risk factors Smoking causes most cases of lung cancer. Being around the smoke from others (secondhand smoke) also raises your risk for lung cancer. However, people who do not smoke and have never smoked have become sick with lung cancer. A review of decades of research has recently shown that smoking marijuana may help cancer cells grow, but there is no direct link between the drug and lung cancer. High levels of air pollution, working with or near cancer-causing chemicals or materials (such as asbestos), and drinking water containing high levels of arsenic can increase your risk for lung cancer. Radiation therapy to the lungs can also increase the risk. Symptoms Early lung cancer may not cause any symptoms. Symptoms you should watch for include: Cough that doesn't go away Coughing up blood Shortness of breath Wheezing Chest pain Loss of appetite Losing weight without trying Fatigue Other symptoms that may be due to NSCLC: Weakness Swallowing difficulty Nail problems Joint pain Hoarseness or changing voice Swelling of the face Facial paralysis Eyelid drooping Bone pain or tenderness Note: These symptoms can be due to other, less serious conditions. It is important to talk to your health care provider. Continue reading this article
