What Is a Bronchoscopy?

Bronchoscopy is a medical procedure that allows doctors to look inside the airways and lungs using a thin, flexible tube with a light and camera (called a bronchoscope).

It can be used to:

• Detect lung abnormalities (such as tumors, inflammation, or blockages).
• Take tissue samples (biopsies).
• Guide treatment by removing blockages or delivering medications.

 

How Bronchoscopy Is Used in Cancer

1. Detection & Diagnosis

• Identifies abnormal growths or blockages in the trachea, bronchi, and lungs.
• Collects tissue samples to confirm or rule out lung cancer.
• Retrieves fluid samples (bronchoalveolar lavage) for analysis.

2. Staging

• Determines if lung cancer has spread to the central airways or nearby lymph nodes.

3. Treatment

• Removes airway obstructions caused by tumors.
• Places stents to keep airways open.
• Delivers targeted therapies directly into the lungs.

4. Monitoring

• Checks lung changes after treatment.
• Evaluates recurrence or complications (e.g., infection).

 

Types of Bronchoscopy

• Flexible Bronchoscopy
  • Most common, done under local anesthesia and sedation.
  • Used for diagnosis, biopsies, and fluid collection.
• Rigid Bronchoscopy
  • Performed under general anesthesia.
  • Useful for removing large blockages, placing stents, or controlling bleeding.
• Endobronchial Ultrasound (EBUS)
  • Combines bronchoscopy with ultrasound to examine deeper structures and lymph nodes.
  • Helps with lung cancer staging and guiding biopsies.

 

What to Expect During the Procedure

• You may receive sedation or general anesthesia depending on the type.
• The bronchoscope is inserted through the nose or mouth into the lungs.
• The procedure usually takes 30–60 minutes.
• Some patients experience mild sore throat, cough, or hoarseness afterward.

 

Benefits

• Direct visualization of airways and lungs.
• Allows biopsy and staging in the same procedure.
• Can combine diagnosis and treatment (e.g., removing tumors, stents).
• EBUS provides minimally invasive staging without surgical procedures.

 

Risks & Limitations

• Mild bleeding, infection, or lung irritation.
• Rare risk of lung collapse (pneumothorax) after biopsy.
• Not all lung areas can be reached (may still require CT-guided biopsy or surgery).
• Requires sedation or anesthesia, which may carry risks.

 

Alternatives & Related Tests

• Chest CT Scan: Provides detailed imaging but no tissue sampling.
• PET Scan: Shows metabolic activity of tumors.
• Needle Biopsy (CT-guided): Reaches lung areas not accessible by bronchoscopy.
• Surgical Biopsy: More invasive but sometimes necessary for diagnosis.

 

Questions to Ask Your Doctor

• Why do I need a bronchoscopy?
• Will it be flexible, rigid, or EBUS?
• Will I be sedated or under general anesthesia?
• What are the risks in my case?
• How will the results affect my treatment plan?

 

Patient Tips

• Do not eat or drink for at least 6–8 hours before the procedure.
• Arrange for someone to drive you home after sedation.
• Mild cough or sore throat is normal; contact your doctor if you have severe chest pain, shortness of breath, or heavy bleeding.
• Avoid strenuous activity for 24 hours after the procedure.
