Lung Nodule Biopsy: When Is It Needed and What to Expect
Lung Cancer Screening: Who Should Get a Low-Dose CT Scan?
September 15, 2026
The diagnosis of a lung nodule during a scan can naturally cause concern but not all lung nodules indicate cancer. In fact, many of them are completely harmless and might have appeared because of previous infections, inflammation or even scars. But some nodules need additional investigation for further clarification of their nature.
Based on the statements by Dr. George Karimundackal, a highly respected lung cancer specialist and thoracic surgeon in Mumbai, a careful analysis should be conducted when the lung nodule has certain suspicious features such as the growth, irregular border, or changes over time. Lung nodule biopsy helps doctors examine the tissue and define the nature of the nodule.
Dr. George Karimundackal is known as an expert in the diagnosis and treatment of complicated chest conditions, among which are lung nodules and lung cancer. Being a highly qualified thoracic specialist with skills in minimally invasive procedures, he provides comprehensive care for patients requiring lung nodule evaluation, biopsy and treatment planning.
So, when is a lung nodule biopsy needed, and what happens during the procedure? Let’s understand.
What Is a Lung Nodule Biopsy?
Lung nodule biopsy is a diagnostic method whereby a sample of tissue is taken from a lung nodule. This tissue will be analyzed in a lab to confirm whether the nodule is cancerous, benign, or associated with other lung diseases.
A lung nodule may be identified by:
Although imaging scans give information about the nodule’s size and shape, a tissue analysis is necessary for an accurate diagnosis in many instances.
The results of a lung biopsy for lung nodules helps doctors understand:
- Whether cancer cells are present
- The type of abnormal cells
- The best treatment approach if cancer is diagnosed
Why do some lung nodules need further testing? Let’s understand.
Why Is a Lung Nodule Biopsy Recommended?
Not every lung nodule requires a biopsy. Doctors consider several factors before recommending the procedure.
A biopsy may be advised when:
- The nodule increases in size over time
- The nodule has suspicious features on CT scan
- There is a history of smoking
- The patient has risk factors for lung cancer
- Imaging results cannot confirm the diagnosis
Dr. George Karimundackal, a competent lung cancer specialist in Mumbai, may recommend biopsy when the benefits of obtaining a clear diagnosis outweigh the risks of the procedure.
A biopsy helps avoid unnecessary treatment for harmless nodules while ensuring suspicious nodules are evaluated early.
When is lung nodule biopsy needed? Let’s look at the important factors doctors consider
When Does a Lung Nodule Need a Biopsy?
- Size of the Nodule
- Growth Pattern
- Appearance on CT Scan
- Patient Risk Factors
- PET Scan Findings
Have you been advised to evaluate a lung nodule? Expert assessment can help determine whether a biopsy is required and guide the next steps.
How is a lung biopsy performed? The approach depends on the location and characteristics of the nodule
Types of Lung Nodule Biopsy Procedures
There are different types of lung biopsy procedures:
CT-Guided Needle Biopsy
A thin needle is guided through the chest wall using CT imaging to collect a tissue sample.
Suitable for:
- Nodules located near the outer part of the lung
Bronchoscopy Biopsy
A flexible camera is passed through the airway to collect samples from nodules connected to the bronchial passages.
Suitable for:
- Nodules near the central airways
In some cases, minimally invasive surgery such as VATS (Video-Assisted Thoracoscopic Surgery) may be recommended.
Suitable for:
- Nodules that cannot be safely accessed through other methods
- Nodules requiring complete removal
The choice depends on nodule location, size, patient health and test findings.
How is a lung biopsy performed? Let’s walk through the process.
What Happens During a Lung Biopsy Procedure?
Before the procedure, doctors review imaging scans and medical history.
During a lung biopsy procedure:
The procedure duration varies depending on the biopsy method.
Patients are monitored after the procedure to ensure there are no immediate complications.
What is the lung biopsy recovery time? Let’s understand.
Recovery After Lung Nodule Biopsy: What Patients Should Expect
Recovery depends on the type of biopsy performed.
After a needle biopsy, patients may experience:
- Mild chest discomfort
- Temporary soreness
- Small amount of coughing
After surgical biopsy, recovery may take a few days due to the minimally invasive procedure.
Patients are usually advised to:
- Follow post-procedure instructions
- Avoid strenuous activities for the recommended period
- Report symptoms such as increasing chest pain or breathing difficulty
Your doctor will guide you based on your specific procedure and health condition.

Lung Nodule Biopsy Results and Next Steps
The collected tissue is examined by a pathologist. Lung biopsy results may show:
Based on the findings, doctors may recommend:
- Regular CT monitoring
- Additional investigations
- Surgery
- Cancer treatment options
A proper diagnosis helps create a personalised treatment plan.
Risks and Complications of Lung Nodule Biopsy
Like any medical procedure, a lung biopsy has some possible risks.
Common risks of lung biopsy include:
Doctors take precautions to reduce these risks and carefully select the safest biopsy method.
The benefits of obtaining an accurate diagnosis often help guide appropriate treatment decisions.

Frequently Asked Questions
Usually when a nodule grows, looks suspicious, or can’t be figured out from scans alone.
Not at all. Many are benign and come from infections, inflammation, or scarring.
A biopsy may be performed using a needle, bronchoscopy, or minimally invasive surgery depending on the nodule location.
Recovery varies depending on the biopsy type. Many patients return to normal activities within a short period after minor procedures.
Possible risks include bleeding, infection, and air leakage around the lung.
