Your scan shows something unusual in the lungs. Maybe there is a persistent infection that is not responding to treatment, a suspicious area on a CT scan, or a cough that has refused to go away.
Then your doctor mentions a procedure called a bronchoscopy.
The first reaction is often, “Why do I need a camera in my lungs?”
It sounds more intimidating than it actually is. A bronchoscopy is a procedure that allows a doctor to look inside the airways and, when needed, collect samples to understand what is causing a respiratory problem.
A bronchoscopy uses a thin tube called a bronchoscope to examine the airways inside the lungs.
In most modern diagnostic procedures, a flexible bronchoscope is used. It is carefully passed through the nose or mouth and into the breathing passages.
The doctor can see the airways and may collect mucus, fluid, cells, or small tissue samples for laboratory testing.
The procedure is used for diagnosis and, in selected situations, treatment.
A CT scan or chest X-ray may show an abnormal area, but imaging does not always explain exactly what it is.
A bronchoscopy may allow the doctor to examine the airways directly and collect a sample for further testing.
This can be particularly useful when the result could change the treatment plan.
Most respiratory infections improve with appropriate treatment.
But when a serious infection continues despite treatment, your doctor may need to determine exactly which organism is involved or whether something else is contributing to the problem.
Samples obtained during bronchoscopy can sometimes provide information that routine sputum testing cannot.
Coughing up blood can happen for several reasons, ranging from relatively minor problems to serious lung conditions.
If your doctor believes the airways need direct examination, bronchoscopy may be considered as part of the evaluation.
However, significant or rapidly increasing bleeding requires urgent medical attention.
Sometimes an airway can become blocked by mucus, a foreign object, or another abnormality.
In selected cases, bronchoscopy can help identify the blockage and may also allow the doctor to remove it.
Before the procedure, the medical team will explain what will happen and review your medical history and medicines.
You may receive local anaesthetic to numb the nose and throat, along with medication to help you relax. Some procedures may be performed with deeper sedation or anaesthesia depending on what is planned.
The bronchoscope is then guided into the airways.
The doctor examines the breathing passages and takes any necessary samples.
The exact duration varies depending on the reason for the procedure and whether additional interventions are required.
Most patients are concerned about this.
A flexible bronchoscopy is generally performed with anaesthesia or sedation to make the procedure more comfortable. You may experience coughing or a sensation of pressure during or after the procedure.
A sore throat or mild cough can occur afterward.
Your medical team will give you specific instructions about eating, drinking, medicines, and what symptoms should prompt you to contact them after the procedure.
Consider a patient with persistent pneumonia that has not improved as expected after treatment.
A CT scan shows an area of abnormality, but the cause remains unclear. The doctor may recommend bronchoscopy to inspect the airways and collect samples.
If laboratory testing identifies a specific infection, treatment can then be adjusted accordingly. If no infection is found, the medical team can investigate other possible causes.
The benefit is simple: better information can lead to a more targeted treatment decision.
This is important.
A bronchoscopy is not automatically the next step just because a scan shows something unusual.
Sometimes imaging, blood tests, sputum testing, or follow-up scans can provide enough information. In other cases, a tissue or airway sample may be necessary.
The procedure should be recommended because it answers an important medical question—not simply because it is available.
Your doctor should be able to explain what they are looking for and how the result could change your treatment.
Yes, in selected cases.
If imaging shows a suspicious lesion or abnormality, bronchoscopy may allow doctors to examine the airways and collect cells or tissue for laboratory analysis.
However, not every lung lesion can be reached effectively through a bronchoscope. The location and appearance of the abnormality help determine whether bronchoscopy or another biopsy approach is more appropriate.
A suspected cancer diagnosis should always be confirmed using appropriate testing rather than imaging alone.
Lung diseases remain a major health concern worldwide.
According to the World Health Organization's 2024 global cancer estimates, lung cancer remained among the most commonly diagnosed cancers worldwide and was the leading cause of cancer death globally.
That does not mean every abnormal scan represents cancer. In fact, many lung findings have non-cancerous causes.
It does mean that unexplained or suspicious findings deserve the right follow-up rather than being ignored.
Bronchoscopy is widely used and is generally considered a safe procedure when performed by an appropriately trained medical team.
However, like any medical procedure, it carries potential risks. These can include bleeding, infection, breathing difficulties, reactions to sedation, or a temporary drop in oxygen levels.
The level of risk depends on the patient's health and the type of bronchoscopy being performed.
Your doctor should explain the expected benefits and potential risks before you give consent.
Tell your doctor about all medicines you take, especially blood-thinning medicines.
Also mention allergies, heart or lung conditions, previous reactions to anaesthesia or sedation, and any recent respiratory infection.
Do not stop prescribed medicines on your own. Your doctor will tell you if anything needs to be adjusted before the procedure.
Dr. Nikhil Modi is a pulmonary and critical care specialist who evaluates patients with complex respiratory problems. When imaging shows an unexplained lung abnormality, persistent infection, airway blockage, or another concern requiring direct examination, bronchoscopy may be considered to obtain valuable diagnostic information and help guide further treatment.
You may have a mild sore throat or cough for a short period.
If tissue, fluid, or other samples were collected, they may need to be sent to a laboratory. Some results may be available quickly, while biopsy or specialised tests can take longer.
Your doctor will explain which results are expected and when they should be reviewed.
Contact your medical team if you develop significant bleeding, severe breathing difficulty, persistent high fever, or other concerning symptoms after the procedure.
A bronchoscopy may be recommended to investigate abnormal scans, persistent lung infections, unexplained coughing up of blood, suspected airway blockage, or suspicious areas that require samples for diagnosis.
Flexible bronchoscopy is generally a minimally invasive procedure. It is usually performed with local anaesthesia, sedation, or both, depending on the situation. The exact approach depends on the procedure being performed and the patient's health.
Most people recover relatively quickly from a routine flexible bronchoscopy, although mild coughing or throat irritation may occur afterward. Recovery can vary depending on the type of procedure and whether biopsies or other interventions were performed.
Hearing the word “bronchoscopy” can make a respiratory problem feel much more frightening.
But the purpose of the procedure is usually straightforward: look more closely, collect better information, and make a more informed treatment decision.
Not everyone with an abnormal scan or persistent cough needs a bronchoscopy. The decision should depend on your symptoms, test results, medical history, and what your doctor needs to find out.
If your doctor has recommended a bronchoscopy or you have an unexplained respiratory problem requiring further investigation, discuss whether bronchoscopy procedures in Govindpuri are appropriate for your condition.
