- To help find the cause of symptoms, your doctor will review your medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer. He or she will also perform a physical exam, and may order a chest x-ray and other tests. To confirm the presence of lung cancer, the doctor must examine suspicious tissue from the lung. To do this, the doctor removes a small sample of the tissue during a procedure called a biopsy. Then the tissue is examined under a microscope.
- Chest x-ray: check were the cancer is and the size of the tumor.
- Computed Tomography (CT) scan: Finds nodules smaller than a x-ray.
- Biopsy: confirms the presence of cancer.
