What Is Lymph Node Surgery?
Lymph node surgery (lymphadenectomy) is a surgical procedure to remove one or more lymph nodes for examination or treatment. It is most commonly performed to diagnose lymphoma, determine if cancer has spread (staging), or remove lymph nodes containing cancer cells. The procedure is done under general anesthesia and typically requires a short hospital stay.
Lymph nodes are small, bean-shaped structures that are part of your body's lymphatic system and immune defense. They filter lymphatic fluid and help fight infections. Lymph nodes are located throughout your body, with major clusters in the neck, armpits (axillary nodes), chest, abdomen, pelvis, and groin (inguinal nodes).
When doctors suspect cancer or other diseases affecting the lymphatic system, they may recommend surgery to remove lymph nodes for microscopic examination. This provides crucial information about the nature of the disease and helps guide treatment decisions. The extent of surgery depends on the underlying condition being investigated or treated.
There are several types of lymph node surgery, each serving different purposes. A sentinel lymph node biopsy removes only the first lymph node(s) where cancer cells would likely spread, minimizing the extent of surgery. A lymph node dissection or complete lymphadenectomy removes a larger group of lymph nodes in a specific region when cancer spread is confirmed or suspected.
Why Is Lymph Node Surgery Performed?
There are several medical reasons why your doctor may recommend lymph node surgery. Understanding the purpose helps you prepare mentally and physically for the procedure.
Cancer diagnosis and staging is the most common reason for lymph node surgery. When cancer is detected in an organ, the lymph nodes are often the first place it spreads. Examining lymph nodes under a microscope tells doctors whether cancer has metastasized and helps determine the stage of the disease. This information is critical for planning appropriate treatment, including whether chemotherapy or radiation therapy is needed.
Lymphoma diagnosis requires lymph node tissue for accurate classification. Lymphoma is a cancer that originates in the lymphatic system itself. Different types of lymphoma require different treatments, and examining the lymph node architecture and cell types under a microscope is essential for proper diagnosis.
Treatment of metastatic cancer may involve removing lymph nodes that contain cancer cells. In some cases, removing affected lymph nodes can help control the spread of cancer and improve outcomes, particularly in breast cancer, melanoma, and head and neck cancers.
Diagnosis of infections and other conditions such as tuberculosis, sarcoidosis, or other inflammatory conditions may also require lymph node biopsy when the cause of swollen lymph nodes is unclear.
The lymphatic system is a network of vessels and nodes that carries lymph fluid throughout your body. This fluid contains white blood cells that help fight infection. Lymph nodes act as filters, trapping bacteria, viruses, and abnormal cells including cancer cells. Learn more about how the lymphatic system functions.
How Should I Prepare for Lymph Node Surgery?
Preparation for lymph node surgery includes fasting for 6-8 hours before the procedure, stopping certain medications (especially blood thinners), and showering with antiseptic soap the night before and morning of surgery. Avoiding alcohol and tobacco for several weeks before and after surgery significantly reduces complications and improves healing.
Proper preparation for surgery is essential for a successful outcome and smooth recovery. Your healthcare team will provide specific instructions tailored to your situation, but there are general guidelines that apply to most lymph node surgeries.
Medication review is an important first step. Inform your doctor about all medications you take, including prescription drugs, over-the-counter medicines, supplements, and herbal products. Blood-thinning medications such as warfarin, aspirin, or newer anticoagulants may need to be stopped several days before surgery to reduce bleeding risk. Your doctor will advise you on which medications to stop and when to resume them after surgery.
Fasting requirements are strictly enforced before any procedure requiring general anesthesia. Typically, you should not eat or drink anything for at least 6-8 hours before your scheduled surgery time. An empty stomach reduces the risk of aspiration, a serious complication where stomach contents enter the lungs during anesthesia. Your surgical team will give you specific instructions about when to stop eating and drinking.
Antiseptic washing helps reduce the bacterial load on your skin and decreases infection risk. You will typically be instructed to shower with chlorhexidine soap (a special antiseptic cleanser) the evening before surgery and again on the morning of your procedure. Pay particular attention to the area where the incision will be made.
Lifestyle Modifications Before Surgery
Certain lifestyle changes can significantly improve your surgical outcome and recovery. While these recommendations apply to all surgeries, they are particularly important for procedures involving the lymphatic system.
Stop smoking at least 4-6 weeks before surgery if possible. Smoking impairs blood flow to tissues, delays wound healing, and increases the risk of infection and other complications. The lungs also need to be in optimal condition for anesthesia. If you cannot quit completely, even reducing smoking in the weeks before surgery provides some benefit.
Avoid alcohol for at least one week before surgery. Alcohol can interact with anesthesia medications and affect blood clotting. Heavy drinkers may experience withdrawal symptoms during hospitalization, which can complicate recovery. After surgery, avoid alcohol until your doctor confirms it is safe to resume.
Arrange support for your recovery period. You will not be able to drive yourself home after surgery due to the effects of anesthesia. Plan for someone to stay with you for at least the first 24-48 hours after discharge. Consider arranging help with household tasks, meals, and caring for children or pets during your recovery period.
Before your surgery date, ensure you have: completed all required pre-operative tests, arranged transportation home, prepared comfortable loose-fitting clothes for your hospital stay, organized help at home for the recovery period, and understood all fasting and medication instructions.

How Is Lymph Node Surgery Performed?
Lymph node surgery is performed under general anesthesia. The surgeon makes an incision in the skin over the lymph node location, carefully removes the affected lymph node(s), and closes the wound with sutures. The procedure typically takes 1-3 hours depending on the number and location of nodes being removed.
Understanding what happens during surgery can help reduce anxiety and prepare you for what to expect. While specific techniques may vary based on the location and purpose of the surgery, the general approach is similar for most lymph node procedures.
Anesthesia administration begins before the surgery starts. For lymph node surgery, general anesthesia is typically used, meaning you will be completely asleep and feel no pain during the procedure. An anesthesiologist or nurse anesthetist monitors your vital signs throughout the operation and adjusts medications as needed to keep you safe and comfortable.
The surgical incision is made over the area containing the lymph nodes to be removed. The size and location of the incision depend on which lymph nodes are being accessed. For example, axillary lymph node surgery requires an incision in the armpit area, while inguinal lymph node surgery involves an incision in the groin. The surgeon carefully works through layers of tissue to reach the lymph nodes while preserving surrounding structures.
Lymph node removal is performed with precision to ensure complete removal while minimizing damage to nearby blood vessels, nerves, and other tissues. For a sentinel lymph node biopsy, a special dye or radioactive tracer may be injected before surgery to identify the specific nodes that need removal. For a complete lymph node dissection, the surgeon removes all lymph nodes in a defined anatomical region.
Wound closure completes the procedure. The surgeon carefully sutures (stitches) the incision closed in layers. Depending on the extent of surgery and the location, a drainage tube may be placed to prevent fluid accumulation in the surgical site. The wound is then dressed with sterile bandages.
Types of Lymph Node Surgery
Several different surgical approaches exist for lymph node removal, each suited to specific clinical situations. Your surgeon will recommend the most appropriate technique based on your diagnosis and treatment goals.
Sentinel lymph node biopsy (SLNB) is a minimally invasive procedure that identifies and removes only the first lymph node(s) in the drainage pathway from a tumor. This technique is commonly used in breast cancer and melanoma staging. If the sentinel node is cancer-free, further lymph node removal is usually unnecessary, reducing the risk of complications like lymphedema.
Complete lymph node dissection (CLND) involves removing all lymph nodes in a specific region. This may be performed when cancer spread to lymph nodes is confirmed or when comprehensive staging is required. While more extensive than sentinel node biopsy, complete dissection may be necessary to adequately treat or stage certain cancers.
Selective lymph node dissection removes a specific subset of lymph nodes in a region based on the known patterns of cancer spread. This approach balances the need for accurate staging and treatment with minimizing surgical morbidity.
When Will I Get My Results?
Lymph node biopsy results typically take 1-2 weeks. The removed tissue is sent to a laboratory where a pathologist examines it under a microscope. Your referring physician will contact you to discuss the findings and explain what they mean for your diagnosis and treatment plan.
Waiting for biopsy results can be an anxious time, but understanding the process may help manage expectations. The analysis of lymph node tissue is a detailed and careful process that takes time to ensure accurate results.
Laboratory processing begins immediately after surgery. The removed lymph nodes are placed in a preservative solution and transported to the pathology laboratory. There, the tissue is processed, embedded in wax, sliced into extremely thin sections, and stained with special dyes that highlight different cell types and structures.
Microscopic examination is performed by a pathologist, a doctor specialized in diagnosing diseases by examining tissues and cells. The pathologist looks for abnormal cells, determines whether cancer is present, identifies the type of cancer if found, and assesses how far it has spread within the lymph node. Additional specialized tests may be ordered to further characterize the findings.
Results communication typically occurs during a follow-up appointment with the physician who referred you for surgery. The doctor will explain the pathology findings, discuss what they mean for your condition, and outline recommended next steps in your care. It is helpful to bring a family member or friend to this appointment to help remember the information discussed.
When you receive your results, consider asking: What did the biopsy show? What does this mean for my diagnosis? What are my treatment options? What happens next? Are there any additional tests needed? Having someone with you to take notes can help ensure you remember important information.
What Should I Expect During Recovery?
Most patients leave the hospital 1-2 days after lymph node surgery. Complete wound healing takes 4-6 weeks, during which you should avoid heavy lifting, strenuous exercise, and swimming. You may have a drainage tube for several weeks and will receive medications for pain management and infection prevention.
Understanding the recovery process helps you plan appropriately and know what is normal after surgery. While everyone heals at their own pace, there are general milestones and expectations that apply to most lymph node surgery patients.
Immediate post-operative period begins in the recovery room where medical staff monitors you as the anesthesia wears off. Once you are awake and stable, you will be moved to a hospital room. You can expect some pain and discomfort at the surgical site, which is managed with medication. Most patients can eat and drink within a few hours of surgery and begin walking the same day or the next morning.
Hospital discharge typically occurs 1-2 days after surgery, depending on the extent of the procedure and how well you are recovering. Before leaving, you will receive detailed instructions about wound care, medications, activity restrictions, and warning signs that require medical attention. Ensure you understand all instructions and have necessary supplies at home before discharge.
Wound care at home is essential for proper healing and infection prevention. Keep the surgical site clean and dry as instructed. Your healthcare team will advise when you can shower and how to care for the incision. Watch for signs of infection including increasing redness, swelling, warmth, pus or foul-smelling discharge, and fever.
Managing Surgical Drains
Many patients have a drainage tube placed during surgery to collect fluid that accumulates at the surgical site. Understanding how to care for your drain is an important part of recovery.
Drain purpose and function: The drain prevents fluid buildup (seroma) that could delay healing or cause infection. A thin plastic tube connected to a collection bulb or bag allows fluid to drain from the surgical site. You will need to empty the collection container regularly and record the amount of fluid drained.
Drain care: Keep the drain site clean and secure the tubing to prevent pulling. Empty the collection container as instructed, typically when it is about half full. Record the amount and color of fluid at each emptying. Report any sudden increase in drainage, foul smell, or cloudiness to your healthcare team.
Drain removal: The drain remains in place until fluid output decreases to a certain level, typically less than 30ml per day for two consecutive days. This may take several days to several weeks. Drain removal is usually done at a follow-up appointment and takes only a few moments.
Activity Restrictions
Following activity restrictions during recovery is important for proper healing and preventing complications. While it may be frustrating to limit your activities, these precautions are temporary and essential for good outcomes.
Avoid heavy lifting for 2-4 weeks after surgery. The definition of "heavy" varies, but generally means avoiding lifting anything heavier than 5-10 pounds (2-5 kg). This includes grocery bags, laundry baskets, children, and pets. Lifting too early can strain the surgical site and delay healing.
Avoid strenuous exercise for at least 4 weeks. This includes running, weightlifting, tennis, golf, swimming, and other activities that involve vigorous arm or leg movements depending on the surgery location. Walking is encouraged and beneficial for recovery, but consult your doctor before resuming more vigorous activities.
Avoid swimming and bathing until the wound is completely healed, typically 4-6 weeks. Soaking the incision in water can introduce bacteria and cause infection. Showers are usually permitted a few days after surgery, but confirm this with your healthcare team.
What Are the Possible Complications?
Complications from lymph node surgery are uncommon but can include wound infection, bleeding, seroma (fluid collection), nerve damage causing numbness, and lymphedema (chronic swelling). Recognizing warning signs early allows prompt treatment and better outcomes.
While lymph node surgery is generally safe, as with any surgical procedure, complications can occur. Being aware of potential problems helps you recognize them early and seek appropriate care.
Wound infection is a risk with any surgery. Bacteria can enter through the incision and cause infection. Signs include increasing redness, swelling, and warmth around the wound; increasing pain; fever above 38C (100.4F); and discharge of pus or foul-smelling fluid. If you notice any of these signs, contact your healthcare provider promptly. Infections caught early are usually easily treated with antibiotics.
Bleeding and hematoma can occur during or after surgery. While surgeons take great care to control bleeding during the procedure, post-operative bleeding sometimes occurs. Signs include swelling, bruising, and pain at the surgical site that worsens over time. Significant bleeding requires medical evaluation and possibly additional treatment.
Seroma formation is the accumulation of lymphatic fluid at the surgical site. This is a relatively common occurrence after lymph node surgery. Small seromas often resolve on their own, while larger ones may need to be drained with a needle. Wearing compression garments as advised and following activity restrictions helps reduce seroma risk.
Understanding Lymphedema
Lymphedema is one of the most significant potential long-term complications of lymph node surgery. Understanding this condition and how to prevent it is important for anyone undergoing lymph node removal.
What is lymphedema? When lymph nodes are removed, the normal drainage pathways for lymphatic fluid are disrupted. This can cause fluid to accumulate in the affected limb or body part, leading to chronic swelling called lymphedema. The risk is higher when more lymph nodes are removed and varies depending on the surgery location.
Symptoms of lymphedema include a feeling of heaviness, tightness, or fullness in the affected limb; visible swelling; reduced flexibility; recurring infections in the affected area; and thickening or hardening of the skin over time. Symptoms may develop immediately after surgery or years later.
Prevention strategies are crucial and should begin immediately after surgery. These include maintaining physical activity with appropriate exercises, achieving and maintaining a healthy weight, avoiding extreme temperatures on the affected limb, preventing infections by caring for skin and treating cuts promptly, and wearing compression garments if recommended.
Contact your healthcare provider or seek emergency care immediately if you experience: severe pain not controlled by prescribed medication; fever above 38.5C (101.3F); heavy bleeding or blood soaking through the bandage; sudden swelling or hardness at the surgical site; shortness of breath or chest pain; or red streaks spreading from the wound.
How Can I Prevent Lymphedema?
Preventing lymphedema after lymph node surgery involves staying physically active, performing recommended exercises, maintaining a healthy weight, protecting the skin from injury and infection, and wearing compression garments when advised. Early recognition of symptoms allows for prompt treatment that can prevent progression.
While not all cases of lymphedema can be prevented, there are many evidence-based strategies that significantly reduce your risk. These prevention measures should become part of your daily routine after lymph node surgery.
Stay physically active as movement helps lymphatic fluid circulate through the body. Walking, swimming, and other gentle exercises are beneficial. Avoid prolonged periods of sitting or standing in one position. Your healthcare team can recommend specific exercises appropriate for your situation and the location of your surgery.
Perform prescribed exercises regularly. Your physical therapist or healthcare provider may teach you specific exercises to promote lymphatic drainage and maintain flexibility. These exercises are particularly important in the weeks and months following surgery. Continue them long-term as directed.
Maintain a healthy weight as excess body weight increases the risk of lymphedema and makes existing lymphedema more difficult to manage. If you need to lose weight, work with your healthcare team on a safe and sustainable plan.
Protect your skin from cuts, burns, and insect bites, which can lead to infections. Infections in the affected limb can trigger or worsen lymphedema. Use sunscreen, wear gloves when gardening, use insect repellent, and avoid blood draws or injections in the affected arm if possible.
Wear compression garments if recommended by your healthcare provider. Compression sleeves, stockings, or other garments help prevent fluid accumulation and can be worn during activities that may trigger swelling, such as air travel or exercise.
When Should I Contact My Healthcare Provider?
Contact your healthcare provider if you experience signs of infection (fever, increasing pain, redness, or wound discharge), excessive bleeding, worsening swelling, or any symptoms that concern you. Seek emergency care for severe pain, high fever, heavy bleeding, or symptoms of blood clots such as leg swelling, chest pain, or difficulty breathing.
Knowing when to seek medical attention is an important part of your recovery. While some discomfort is normal after surgery, certain symptoms require prompt evaluation.
Routine follow-up appointments should be kept as scheduled. These visits allow your healthcare team to monitor your healing, remove drains when appropriate, discuss biopsy results, and address any concerns. Do not skip these appointments even if you feel well.
Contact your healthcare provider (but not emergency services) for: fever between 37.8-38.5C (100-101.3F); mild to moderate increase in wound redness, swelling, or drainage; constipation or difficulty urinating; mild nausea or decreased appetite; questions about your medications or activity level; and early signs of lymphedema such as slight swelling or heaviness in the affected limb.
Seek emergency care immediately for: severe or worsening pain not relieved by prescribed medication; fever above 38.5C (101.3F); heavy bleeding or blood soaking through bandages; sudden severe swelling; shortness of breath or chest pain; coughing up blood; sudden leg swelling, pain, or redness (possible blood clot); and confusion or difficulty waking.
In a medical emergency, call your local emergency number immediately. Have a list of your medications, allergies, and the name and contact information of your surgeon available. Find your local emergency number.
