Abstract

This paper explores the various diagnostic methods available for the detection of lung cancer. Primarily, it focuses on imaging tests such as X-ray imaging of the lungs, sputum cytology involving microscopic examination of sputum samples, and tissue biopsy procedures such as bronchoscopy and needle biopsy of lung tissue. Additionally, other diagnostic tests including thoracoscopy, mediastinoscopy, and PET scans are discussed. The efficacy, advantages, and limitations of each diagnostic approach are evaluated, providing valuable insights for healthcare professionals involved in the diagnosis and management of lung cancer.
