Sputum analysis involves examining a sample of a patient's phlegm under a microscope for the presence of cancerous cells. This method is non-invasive, simple, and relatively inexpensive, making it a preferred option for identifying lung cancer cells. Thoracentesis, mediastinoscopy, and bronchoscopy are more invasive procedures that are typically used for diagnosing lung cancer after sputum analysis or other tests have suggested the presence of cancerous cells. Gastric lavage is not typically used to identify lung cancer cells as it is a procedure used for emptying the contents of the stomach.
