When a physician suspects that a patient has lung cancer, the diagnosis can be confirmed through several different tests. Imaging scans are often the first step, as they can identify abnormal growths that might require further testing. For instance, a physician may use an X-ray, CT (computed tomography) scan or MRI (magnetic resonance imaging) to get a detailed visual of the patient’s lungs and thoracic cavity.

If an imaging scan shows a growth that could possibly be lung cancer, samples of the lesion may be taken for analysis by a pathologist. Often, a fine needle aspiration will be used. During this procedure, a physician uses a long, hollow needle to take a sample directly from the tumor. However, other tests may be used instead, including:

  • Sputum cytology – A physician takes a sample of mucus that has been coughed up from the lungs. 
  • Endobronchial ultrasound (EBUS) – A physician uses a transbronchial needle aspiration to retrieve tissue or fluid samples from the lungs without having to resort to surgery. Advanced Pulmonary Services: A look at Endobronchial Ultrasound (EBUS)
  • Thoracentesis – A physician drains a build-up of fluid from the cavity around the lungs using a needle.
  • Thoracotomy – A physician removes a tissue or fluid sample during open chest surgery.
  • Bronchoscopy – A physician inserts a flexible, lighted tube (bronchoscope) into the airways of the lungs via the nose or mouth and retrieves tissue or fluid samples.

If a microscopic analysis of the biopsied material confirms that the patient’s growth is cancerous, additional tests will be used to determine whether the cancer has spread to other parts of the body. These tests include PET (positron emission tomography) scans, bone scans and ultrasounds. However, these tests are typically not used until a physician has confirmed a lung cancer diagnosis and is working to determine the cancer’s stage.
