what is a bronchoscopy used to diagnose

Bronchoscopy is mainly used to find the cause of lung or airway problems and to help diagnose specific lung diseases, infections, and cancers.

Quick Scoop: What a Bronchoscopy Can Diagnose

A bronchoscopy lets a doctor look directly inside your windpipe and lungs using a thin tube with a camera, and often take samples (biopsies) for testing. It is usually done when symptoms or scans suggest something is wrong in the airways or lung tissue.

Common reasons and diagnoses

Doctors may use bronchoscopy to help diagnose:

• Lung cancer or tumors (finding suspicious growths and taking biopsies).

• Chronic cough that doesn’t go away, coughing up blood, or unexplained shortness of breath.

• Lung infections such as bacterial pneumonia, tuberculosis, or fungal infections (by sampling mucus or lung fluid).

• Inflammation or scarring in the lungs seen on an X‑ray or CT scan (for example, unexplained lung “spots” or infiltrates).

• Blockages in the airways, such as mucus plugs, foreign bodies, or narrowed segments (strictures).

• Spread and stage of lung cancer by checking lymph nodes in the chest, often with endobronchial ultrasound (EBUS).

In many hospitals today, bronchoscopy is also used as a combined “diagnose and treat” tool: during the same procedure, doctors might remove a tumor or mucus plug, control bleeding, or place a stent to hold a narrowed airway open.

A quick mental picture

You can think of bronchoscopy like sending a tiny camera and toolkit down the airways to find out why the lungs are misbehaving—whether that’s due to cancer, infection, inflammation, or a physical blockage—and sometimes to fix part of the problem on the spot.

Always follow your own doctor’s advice; they order a bronchoscopy based on your specific symptoms, scan results, and overall health.

TL;DR: A bronchoscopy is used to diagnose lung cancer, airway tumors, chronic cough and bleeding, lung infections (like pneumonia or TB), inflammatory lung diseases, and blockages or narrowings in the airways.
