Tests to diagnose lung cancer
- Imaging tests. An X-ray image of your lungs may reveal an abnormal mass or nodule.
- Sputum cytology. If you have a cough and are producing sputum, looking at the sputum under the microscope can sometimes reveal the presence of lung cancer cells.
- Tissue sample (biopsy).
