Medical History and Physical Examination:
 The doctor will review your medical history, including risk factors such as smoking, family history, and exposure to certain substances. They will also perform a physical examination to assess any signs or symptoms associated with lung cancer.

Chest X-ray: This is often the first imaging test performed to identify any abnormalities in the lungs.

Computed Tomography (CT) Scan: CT scans provide detailed cross-sectional images of the lungs, helping to identify the size, location, and spread of tumors.

Positron Emission Tomography (PET) Scan: PET scans use a radioactive tracer to detect cancer cells and determine if the cancer has spread to other parts of the body.

Fine-Needle Aspiration (FNA): A thin needle is used to remove a small tissue sample from a suspicious area for examination under a microscope.

Bronchoscopy: A thin, flexible tube with a camera is inserted through the nose or mouth to view the airways and collect tissue samples.

Mediastinoscopy: A surgical procedure that allows the doctor to examine the lymph nodes in the chest and obtain tissue samples.

Staging: Once a diagnosis of lung cancer is confirmed, staging is performed to determine the extent of the cancer's spread. This may involve additional imaging tests, such as magnetic resonance imaging (MRI), bone scans, or brain imaging.
