What is Pulmonary Nodule?

A pulmonary nodule is defined as a round or oval opacity less than 3 cm in diameter and bounded by surrounding lung tissue in the lung parenchyma. It is being detected with increasing frequency on routine chest X-ray and CT examinations.

The vast majority of nodules are benign in origin (previous granulomatous infection, hamartoma, calcified lymph node). However, the early stage of lung cancer can also present as a nodule.

The size, shape, calcification pattern, and patient risk profile of the nodule determine the decision for follow-up or further investigation. Fleischner Society guidelines are international references guiding these decisions.

Symptoms

Most often gives no symptoms (detected incidentally)
Mild cough in large nodules
Rarely hemoptysis
Fever or weight loss (when malignancy is associated)
Symptoms due to pressure on adjacent structures (in large lesions)

Risk Factors

Smoking
Asbestos or radon exposure
Family history of lung cancer
Previous granulomatous infection (tuberculosis, histoplasma)
Over 60 years of age and male sex

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Pulmonology consultation for incidentally detected nodule on imaging
  • The follow-up recommendation of the radiologist or clinician must be implemented
  • PET-CT or biopsy if the nodule is growing
  • Low-dose CT screening program in high-risk individuals

Treatment Methods

01
Periodic follow-up with CT in low-risk small nodules (according to Fleischner guidelines)
02
PET-CT evaluation in moderate-high-risk nodules
03
Bronchoscopic or percutaneous biopsy (if needed)
04
Surgical resection, radiotherapy, or systemic treatment in malignant nodule
05
Smoking cessation (reduces risk)
