What symptoms of lung cancer do long-term smokers have?

Lung cancer is currently the leading cause of cancer death in the world, which shows how terrible it is. Do you know the symptoms of lung cancer ? Don't worry, the experts will introduce them to us.

Long-term smokers who experience the following symptoms should seek medical attention and be checked for lung cancer. First, an unexplained irritating dry cough that lasts for more than two weeks (sudden, intermittent coughs with little or no sputum). Second, bloody sputum (not coughing up blood, but blood in the sputum, which appears intermittently or continuously). Third, repeated "inflammation" of the same part of the lungs for unknown reasons. These may all be symptoms of early lung cancer. The symptoms of lung cancer are closely related to the early detection of cancer. Only by early detection and timely scientific treatment can the best treatment effect be achieved.

After the above symptoms of lung cancer appear, it is recommended to go to a qualified specialist hospital for diagnosis and treatment in time. Most lung cancers will be detected early. Among the many examination methods, routine chest X-ray examinations include chest X-rays and chest fluoroscopy. Chest X-rays can obtain clearer images, which are convenient for careful observation and analysis; chest X-rays can be observed dynamically and from multiple angles. It is best to take the first sputum in the morning to check for cancer cells in sputum, because the detection rate of sputum cancer cells in some lung cancers is less than 50%, so it is necessary to check multiple times (more than 3 times) to be helpful. In addition, you can further perform chest CT or MRI, and CT is better in comparison, but it is necessary to receive a certain amount of X-ray exposure (the dosage is within the allowable range). In addition, fiber bronchoscopy and thoracoscopy can also be performed; CT-guided lung lesion puncture examination; serum cancer marker examination; PET-CT examination, etc.
