Lymph node removal during a hysterectomy for cancer | CION Cancer Clinics
Lymph nodes are removed during a hysterectomy for cancer to find out whether the cancer has travelled beyond the womb. It is a test, not a sign that it has spread. This page explains which nodes are taken and why, what happens to them, what the words on your pathology report mean, and what to watch for in your legs afterwards. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Why are lymph nodes removed during a hysterectomy for cancer?
Lymph nodes are removed to find out whether the cancer has travelled beyond the womb. Nothing a surgeon can see or feel during the operation answers that question; only the nodes, examined under a microscope afterwards, can.
What a lymph node actually is
A lymph node is a small bean-shaped gland that filters the fluid draining from the tissues around it. When a womb or cervix cancer spreads, the nodes in the pelvis are usually the first place it goes. Removing them is part of staging, the word your team uses for working out how far the cancer has reached.
How the result changes what happens next
If the nodes are clear, your team may decide no further treatment is needed, or only a short course. If a node contains cancer cells, radiotherapy or chemotherapy is more likely to be recommended. The result changes the plan for the months that follow, not the operation you have already had.
Who does not need it
Not every hysterectomy for cancer includes node removal. For some very early womb cancers with a low-risk pattern on the biopsy, the chance of spread is low enough that your team may leave the nodes alone. You are entitled to ask why nodes are or are not being taken.
This page cannot tell you whether your own nodes should be removed. That decision belongs to your treating team.What is taken
Which lymph nodes are removed, and how many?
It depends on the cancer, its grade and what the scans have shown. These are the four approaches your surgeon may describe.
Pelvic nodes
The nodes along the blood vessels on each side of the pelvis. These are the ones most often removed, because they are the first stop for a cancer that is spreading.
Para-aortic nodes
Nodes higher up, along the main artery in the belly. They are removed when the cancer is of a higher grade, or when scans suggest the pelvic nodes may already be involved. This makes the operation longer.
Not every centre removes these routinely. Ask what is planned for you.Sentinel node only
A dye injected into the cervix travels to the first node the womb drains into, called the sentinel node. Only that node, or a few, is removed and checked. If it is clear, the rest are usually left alone, which means less leg swelling later.
Full removal on both sides
All the nodes in the pelvis, and sometimes higher, are taken. This gives the fullest picture but carries a higher chance of leg swelling afterwards. It is chosen when the risk of spread is higher or a node already looks abnormal on the scan.
Not sure whether this applies to you?
Ask an oncologistIn theatre
What happens to the nodes during and after the operation?
Mapping, if a dye is used
While you are asleep, a dye may be injected into the cervix. Over the next few minutes it drains into the first node. The surgeon watches for the colour, or a glow on a special camera, and marks that node.
Removing the nodes
The nodes are lifted away from the blood vessels they sit beside. This is careful, slow work, and the main reason a hysterectomy for cancer takes longer than one done for fibroids. It happens through the same cuts as the rest of the operation.
Sent to the laboratory
Every node is labelled by where it came from and sent to the pathologist, who slices each one thinly and examines it under a microscope. In some centres one node is checked while you are still asleep, but the full report takes longer.
The report and the next plan
The pathology report usually arrives within a couple of weeks. Your case is then discussed by the surgical, medical and radiation oncologists together, and any further treatment is explained to you at a follow-up appointment.
On your report
The words about lymph nodes on your pathology report
- Lymph node, negative
- No cancer cells were found in that node. It is the most common result in early cancers.
- Lymph node, positive
- Cancer cells were found in the node. Further treatment is usually recommended. On its own it says nothing about how you will do.
- Sentinel node
- The first node the womb drains into, found with a dye. If it is clear, the nodes beyond it are very likely clear too.
- Node count, for example 0 of 14
- How many nodes were removed and how many contained cancer. A higher total is not a mark of a better operation.
- Extracapsular spread
- Cancer cells have grown through the outer wall of the node into the fat around it. This nudges the team towards radiotherapy.
- Isolated tumour cells or micrometastasis
- A very small cluster of cancer cells in a node. It is treated differently from a fully involved node, and your team will explain how much weight it carries.

Commonly believed
Four things families ask us about node removal
"If they removed nodes, it means the cancer has already spread."
No. Nodes are removed to find out whether it has spread, not because it has. Most nodes removed in early womb and cervix cancer come back clear. The answer is on the pathology report, not in the fact that it was done.
"Taking out more nodes is always safer."
Removing nodes that were very unlikely to be involved does not lower the chance of the cancer coming back, and it raises the chance of leg swelling for life. This is why sentinel node mapping was developed.
"Without lymph nodes my body cannot fight infection."
You have hundreds of lymph nodes, and the rest keep working normally. What changes is the drainage of fluid from the legs on the side where nodes were taken. Your ability to fight illness is not affected.
"Any leg swelling means the cancer is back."
Swelling in the legs after node removal is far more often lymphoedema, a build-up of fluid because the drainage path has been cut. It needs treatment, but it is not a sign of cancer on its own.

One thing that cannot wait
A leg that becomes swollen, warm, red or painful in the weeks after the operation, especially only one leg, can be a blood clot in a deep vein. Go to the nearest emergency department the same day and say you have recently had cancer surgery with lymph node removal. Do not massage the leg, and do not wait until morning.
Being straight with you
What this page cannot tell you, and what to ask
This page cannot tell you how many nodes will be taken from you, or whether your surgeon will use a dye. That depends on the type and grade of cancer, the scans and what your centre is set up to do.
Questions worth asking before the operation
Ask whether nodes will be removed, and which ones. Ask whether sentinel node mapping is available at your centre and whether it suits your cancer. Ask what the plan would be if a node comes back positive, so the result does not come as a shock. Write the answers down.
Looking after your legs afterwards
Lymphoedema, the fluid swelling in the legs, is the main long-term concern after pelvic node removal. It does not happen to everyone, and it is less common when only sentinel nodes were taken. Keep the skin of the legs and feet clean and moisturised, treat cuts and fungal infections early, avoid tight bands at the ankle, and stay gently active. If a leg starts to feel heavy or tight, tell your team early. Compression and specialist physiotherapy work far better when started soon.
If you do not understand the node section of your report, bring it to the appointment or call the helpline.Questions we are asked
Common questions about lymph node removal with hysterectomy
Does removing lymph nodes make the operation more risky?
It makes it longer, and it adds the chance of leg swelling and a fluid collection in the pelvis afterwards. Bleeding and injury to nearby structures are uncommon. Your surgeon will go through the risks that apply to you at consent.
Will I have more scars because of the node removal?
Usually not. The nodes are reached through the same cuts used for the hysterectomy, whether that is one longer cut on the belly or several small keyhole cuts. Occasionally an extra small cut is needed for the higher nodes.
How long does it take to get the node result?
The full pathology report usually takes a couple of weeks, because each node has to be prepared, sliced and examined. Extra stains on the tissue can add a little time. Ask at discharge when the result is expected and who will explain it to you.
Will I definitely get swollen legs?
No. Many women never develop lymphoedema, and the chance is lower when only sentinel nodes were removed. The risk rises if radiotherapy to the pelvis follows the operation. Skin care, staying active and reporting early heaviness or tightness are the things within your control.
What does a positive node mean for me?
It means cancer cells were found in at least one node, so the stage is higher than the womb alone. Your team will almost always recommend further treatment such as radiotherapy or chemotherapy. What it means for your future depends on the rest of the report, and that conversation belongs with your oncologist.
Can the nodes be checked without removing them?
Scans can suggest a node is enlarged, but they cannot see cancer cells inside a normal-sized node. Removal and examination under a microscope remains the way to know for sure. Sentinel node mapping checks the node that matters most and leaves the rest in place.
Does the number of nodes removed matter?
Less than families tend to think. The number depends on how many nodes happened to be in the area, which varies from person to person. What matters is whether the right area was checked and whether any node was positive.
Is node removal covered by Aarogyasri or insurance?
When it is part of an approved cancer operation, node removal is usually included in the same package. Aarogyasri, CGHS, ECHS and EHS are accepted at CION, and most cashless insurers are empanelled. Call the helpline with your card details and we will check your cover.
