What warning signs of lung cancer should people know about?
Lung cancer often causes no signs at first. Sometimes it is found on an x-ray taken for another reason. As it grows, lung cancer can cause signs.
Lung cancer often causes no signs at first. This includes non-small cell lung cancer, the more common type. Sometimes it is found during a chest x-ray done for an unrelated reason. As lung cancer grows, it can cause symptoms. These include chest pain or discomfort. Another is a cough that does not go away or gets worse over time. Other symptoms are coughing up blood, trouble breathing, and wheezing. Hoarseness, loss of appetite, and weight loss for no known reason can also occur. Feeling very tired and trouble swallowing are other possible signs. Swelling in the face or neck veins can occur too. Your care team can evaluate these signs and order tests to find the cause.
