Is there any screening test for lung cancer?

Screening test for a particular disease means testing when there are no complaints or history of that disease.

  • Sputum cytology: Your doctor may order a sputum test in which your sputum will be examined under a microscope to look for the presence of cancerous cells.
  • Biopsy: This is a minor surgical procedure in which a sample of abnormal cells is removed. This can be done in any of the various ways:
