Imaging: Chest X-rays, CT scans, and PET scans are essential in identifying abnormal growths or nodules in the lungs. A biopsy may be performed to determine whether the nodules are benign or malignant.
Bronchoscopy: This allows direct visualization of the airways and possible biopsy collection.
Biopsy: A needle biopsy or surgical biopsy can confirm the diagnosis by obtaining a tissue sample for histopathological examination.
Sputum Cytology: Examination of sputum under a microscope to detect cancer cells.
Blood Tests: While not definitive, blood tests can assist in overall health evaluation.
