This may reveal an obvious mass, widening of the [[mediastinum]] (suggestive of spread to [[lymph node]]s there), [[atelectasis]] (collapse), consolidation ([[pneumonia]]), or [[pleural effusion]].

** An obvious mass
If there are no x-ray findings but the suspicion is high (such as a heavy smoker with blood-stained sputum), [[bronchoscopy]] and/or a [[CT scan]] may provide the necessary information. Bronchoscopy or CT-guided [[biopsy]] is often used to identify the tumor type.
** Widening of the [[mediastinum]]  
 
** [[Atelectasis]]
The [[differential diagnosis]] for patients who present with abnormalities on chest x-ray includes lung cancer, as well as nonmalignant diseases. These include infectious causes such as [[tuberculosis]] or pneumonia, or inflammatory conditions such as[[sarcoidosis]]. These diseases can result in [[mediastinum|mediastinal]] [[lymphadenopathy]] or lung [[nodule (medicine)|nodules]], and sometimes mimic lung cancers.

Overview

Performing a chest x-ray is the first step if a patient reports symptoms that may be suggestive of lung cancer. Often lung cancers are picked up on a routine chest X-ray in a person experiencing no symptoms.
