Tests that will assist your doctor in making an accurate diagnosis of lung cancer are:
- Chest X-ray
- Computed Tomography (CT Scan)
- Bronchoscopy: a small scope is passed into the lungs, via the mouth or nose, for direct observation of tumor and to obtain a biopsy.
- Pulmonary function testing
- Needle aspiration: A needle is inserted through the chest into the tumor to remove a sample of tissue.
- Thoracentesis: using a needle, the doctor removes a sample of the fluid that surrounds the lungs to check for cancer cells.
- Thoracotomy: a surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is major surgery.
- Positron-Emission Tomography (PET scan): this test is helpful in detecting lung cancer and identifying the spread of cancer to other organs.
