Mediastinoscopy and chest staging surgery | CION Cancer Clinics
A mediastinoscopy is a short operation to sample the lymph nodes in the centre of the chest. It shows whether a lung cancer has reached them, and that decides whether surgery to remove the cancer is the right first step. It is done under a general anaesthetic through a small cut at the base of the neck, and most people go home the same day or next morning. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is a mediastinoscopy, and why is it used for lung cancer?
A mediastinoscopy is a short operation to take samples from the lymph nodes in the centre of your chest. It shows whether a lung cancer has reached those nodes, and that answer decides whether surgery to remove the cancer is the right first step.
Why those glands matter so much
Lymph nodes are small glands that filter fluid from the tissues. The mediastinum is the space in the middle of the chest, between the lungs, where the windpipe, heart and many of these glands sit. Lung cancer often travels there first. If cancer is found in them, most teams recommend chemotherapy, radiotherapy or other drug treatment before or instead of an operation.
Why a scan is not enough
A CT or PET-CT judges a gland by its size and how active it looks. A normal-sized gland can still hold cancer, and a bright one may only be inflamed from an old infection, which is common in India because of past tuberculosis. Before a major lung operation, the team often wants tissue rather than a picture.
Mediastinoscopy does not remove the lung cancer. It stages it, so the treatment that follows fits what is really there.Two ways to sample
How is EBUS different from mediastinoscopy?
EBUS needle sampling
Mediastinoscopy
A thin scope goes down the windpipe through the mouth, with no cut
A small cut just above the breastbone, at the base of the neck
Usually sedation or a light anaesthetic
A general anaesthetic
Takes small needle samples, guided by ultrasound
Takes larger pieces of the glands
Often the first test offered
Often used when EBUS is clear but the scan still looks worrying
Not sure whether this applies to you?
Ask an oncologistOn the day
What happens during a mediastinoscopy?
Preparation
You will be asked not to eat for some hours. Tell the team about blood thinners, diabetes tablets and any heart problem. They will tell you what to do with each medicine; do not stop one on your own.
The small cut
Once you are asleep, the surgeon makes a short cut in the skin crease just above the breastbone. A lighted tube is passed down alongside the windpipe, into the centre of the chest.
Sampling the glands
Glands on both sides of the windpipe and below where it divides are found and sampled. Each is labelled by its position, because the location matters for staging.
Closing and waking
The cut is closed with dissolving stitches or glue. You wake in the recovery area, usually with a sore throat and a stiff feeling at the base of the neck.
Going home
Many people go home the same day or the next morning. A chest X-ray may be done before you leave. The full report follows in several days.
Other chest staging operations
Which other operations are used to stage cancer in the chest?
Mediastinoscopy cannot reach every gland or surface. These are the other operations your team may mention.
Anterior mediastinotomy
A small cut beside the breastbone reaches glands on the left side that a mediastinoscope cannot. It is sometimes called a Chamberlain procedure.
Thoracoscopy (VATS)
Keyhole surgery through the side of the chest. A camera looks at the lining of the lung and chest wall and samples glands or fluid there.
Often used when
- Fluid has collected around the lung
- Spots are seen on the chest lining
Pleural fluid sampling
Fluid around the lung is drained with a needle and checked for cancer cells. It is not an operation, but it can stage the cancer on its own if cells are found.
Staging at the main operation
When lung cancer is removed, the surgeon also removes glands from set positions in the chest. Their report gives the final stage.
This is why the stage can change after surgery, even when earlier staging was clear.Leave a number, we will call you

After you go home: what cannot wait
Go to the nearest emergency department the same day if you have new or worsening breathlessness, chest pain, swelling at the neck that is growing, bleeding from the wound that does not stop with firm pressure, or a fever with shivering. A mildly sore throat and a slightly hoarse voice are common; sudden trouble breathing is not.
Commonly believed
What do families often believe about chest staging?
"The PET-CT showed the glands are fine, so this is unnecessary."
A clear PET-CT is good news, but for some tumours, especially larger or central ones, small deposits in the glands can still be missed. Your team may want tissue before recommending a major lung operation.
"A bright gland on the scan means the cancer has spread."
Not always. Old tuberculosis and other infections can make glands bright for years. That is one of the main reasons for sampling rather than deciding from the scan alone.
"If the glands have cancer, nothing more can be done."
It changes the plan, not the fact that there is one. Chemotherapy, radiotherapy, immune treatment and sometimes surgery later are all used when the glands are involved. Ask what is being recommended and why.
Being straight with you
Who is it not suitable for, and what can this page not tell you?
Mediastinoscopy is not needed when EBUS or another test has already confirmed cancer in the glands, or when spread elsewhere means an operation is not being planned. It can be difficult or unsafe after earlier surgery or radiotherapy to the neck or chest, or with some abnormal blood vessels, and in those cases another route is chosen.
What this page cannot tell you
It cannot tell you whether you need this test, what it will find or what your stage will be. Those depend on your scans, your cancer and your health, and only your team can weigh them together.
Questions to ask before you agree
Has EBUS been considered, and why is surgery preferred? Which glands are you sampling, and why those? What will you recommend if they are clear, and if they are not? What are the risks for someone with my health? Bring the family member who helps with decisions.
Questions we are asked
Common questions about mediastinoscopy
Will there be a scar on my neck?
There is a short scar just above the breastbone, usually placed in a natural skin crease. It tends to fade to a thin line over the following months. People who wear a collar or a dupatta often find it is hardly visible. Ask your surgeon to show you where it will sit.
Why is my voice hoarse afterwards?
The breathing tube used during the anaesthetic can irritate the throat. Less often, a nerve to the voice box running near the glands is stretched. Mild hoarseness usually settles on its own. If your voice has not improved at your follow-up, tell your surgeon so it can be checked.
Is mediastinoscopy risky?
Serious problems are uncommon, but it is still an operation close to large blood vessels, so bleeding is the risk surgeons plan for most carefully. Other risks include infection, voice changes and air leaking around the lung. Your surgeon should explain the risks that apply to your own health before you sign.
How soon can I have my lung operation after this?
If the glands are clear and surgery is advised, the main operation can often follow soon, once the report is back. Some teams do both under the same anaesthetic when a quick reading of the samples is clear. Ask which your team plans, so your family can prepare.
Is this used for cancers other than lung cancer?
Yes, sometimes. It can be used to get tissue from enlarged glands in the chest when lymphoma is suspected, or when the cause of enlarged glands is unclear and a needle test has not given an answer. The operation itself is the same.
What does "the glands were positive" mean for my stage?
It means cancer was found in the sampled glands, which usually moves the stage up. Which glands were involved, and on which side, matters too. Your oncologist will explain how that changes what is recommended. The words on the report are written for doctors, so do not try to decode them alone.
Can I eat and talk normally afterwards?
Yes, usually later the same day once you are fully awake. Your throat may be sore, so soft food and warm drinks are easier at first. Talking is fine, though resting a hoarse voice for a few days helps. Tell the team if swallowing is painful or getting worse.
Is it covered by Aarogyasri or insurance?
It is usually covered when it is part of an approved cancer diagnosis or treatment plan. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. Approval may be needed separately from any later lung operation. Call the helpline with your card details and we will check your cover.
