Diagnosis of Lung Cancer

Diagnosis of Lung Cancer

1.Screening

Lung cancer must be found as early as possible. For early diagnosis, an initial Lung Cancer screening is recommended for people who have no symptoms and meet the following criteria:

  • People aged between 55 to 80 years who smoked for a minimum of 30 years
  • Continue to smoke or left smoking in the last 15 years

2.Physical Examination

Once suspected of lung cancer, a doctor will conduct a physical examination and will need the detailed history of the patient. Various Blood Tests are also performed to determine Lung Cancer symptoms and risk factors and to check for any possible clinical signs of the disease. Physical signs may include:

  • Abnormal pulmonary sounds
  • Enlarged lymph nodes
  • Unintentional weight loss
  • Fingernail clubbing

3.Chest X-ray

The X-Ray of the chest is typically the first examination performed to determine any issues based on the detailed history and physical test. It may indicate mass in the lungs or lymph nodes that are swollen.

4.CT scan

A CT scan is always the second phase, either to follow up on an irregular X-Ray finding in the chest or if the cause of troubling symptoms is not clear to the doctor yet. CT scanning involves a series of X-rays that produce a 3D image of the lungs. Unless the CT is anomalous, the Lung Cancer diagnosis also requires validation by analyzing a sample of lung tissue.

5.Lung Biopsy

Lung Biopsy is done to ascertain whether the abnormality is cancer and to ascertain the type of Lung Cancer. The Biopsy material may be collected by bronchoscopy, Ultrasound endobronchial, fine needle aspiration, thoracentesis, or mediastinoscopy.

6.Sputum cytology

Sputum cytology is the easiest way to confirm the diagnosis and to determine the form of lung cancer, but its use is limited to those tumors which extend into the airways.
