Surgery plays a surprisingly limited role in most lymphoma treatment compared with other cancers, but it is far from absent. Because lymphoma responds well to chemotherapy, immunotherapy, and radiation, surgeons rarely try to cut the disease out the way they would a solid tumor in the breast or colon. Instead, surgery serves several distinct purposes: obtaining tissue for diagnosis, removing the spleen when it harbors certain subtypes, handling emergencies like bowel perforation, and implanting the vascular access devices that deliver months of chemotherapy. What each procedure involves and what recovery looks like depends entirely on which of these roles surgery is filling.
The Biopsy That Starts Everything
For most people, the first and sometimes only surgery related to lymphoma is a biopsy. Lymphoma has dozens of subtypes, and telling them apart requires a generous sample of tissue that pathologists can study under the microscope and run specialized staining on. The gold standard is an excisional biopsy, where a surgeon removes an entire enlarged lymph node, typically from the neck, armpit, or groin. This is usually a short outpatient procedure under local or general anesthesia, with a small incision and a recovery measured in days rather than weeks. Soreness, mild swelling, and bruising around the incision site are normal and generally resolve within a week or two.
A less invasive option is a core needle biopsy, where a radiologist uses imaging guidance to push a hollow needle into the node and pull out a thin cylinder of tissue. It is quicker, cheaper, and easier on the patient. The trade-off is diagnostic accuracy. One study found that excisional biopsy provided an adequate sample for diagnosis about 95% of the time, while core needle biopsy achieved adequate tissue roughly 57% of the time.1Blood. Assessment of the Diagnostic Accuracy of Core Needle Biopsies in the Diagnosis of Lymphoma Another study focusing on cervical lymph nodes reported that core needle biopsy gave the correct lymphoma diagnosis in only 66% of cases, was inconclusive in 14%, and identified the wrong subtype in 18%.2PubMed. Core needle biopsy is an inferior tool for diagnosing cervical lymphoma compared to lymph node excision Other data paint a somewhat more favorable picture: in one series, over 92% of patients biopsied by core needle received a diagnosis sufficient to start treatment without needing a second procedure, a rate comparable to excisional biopsy.3PubMed Central. Should Core Needle Lymph Node Biopsy be a Relevant Alternative to Surgical Excisional Biopsy in Diagnostic Work Up of Lymphomas?
The practical takeaway is that a core needle biopsy can sometimes get the job done, particularly when the node is deep inside the chest or abdomen and an excisional biopsy would mean a bigger operation. But when the node is accessible and the clinical suspicion for lymphoma is high, most guidelines still favor excisional biopsy because misclassifying the subtype can mean the wrong treatment.
How Imaging Replaced Surgical Staging
Decades ago, many lymphoma patients underwent a staging laparotomy, an open abdominal surgery where the surgeon would inspect organs, remove the spleen, and take multiple biopsies to determine how far the disease had spread. That era is over. The 2014 Lugano Classification, the current expert recommendation for lymphoma staging, relies on PET/CT scans as the routine staging tool for lymphomas that take up the tracer.4PubMed. PET/CT for Staging; Past, Present, and Future PET/CT proved superior to standalone CT in detecting involved sites, and its adoption effectively eliminated the need for surgical staging in the vast majority of cases.5PubMed. Current role of FDG PET/CT in lymphoma This was a genuine revolution for patients: one scan replaced a major operation, its weeks of recovery, and its permanent consequences like losing a spleen.
When the Spleen Has to Come Out
Splenectomy, or surgical removal of the spleen, remains relevant for a specific group of lymphomas that settle primarily in the spleen. Splenic marginal zone lymphoma is the classic example. In these cases, the spleen itself may be massively enlarged, causing pain, early fullness when eating, and low blood counts because the overactive spleen traps too many blood cells. Splenectomy serves a dual purpose: it provides the definitive tissue diagnosis and, by removing the main site of disease, functions as treatment.6PubMed. The role of splenectomy in management of splenic B-cell lymphomas Guidelines recommend splenectomy for patients with symptomatic enlargement, low blood counts, systemic symptoms, or aggressive nodal disease, while those without such features may simply be monitored.7PubMed Central. Splenic marginal zone lymphoma treated with laparoscopic splenectomy: A case report
Today, most splenectomies for lymphoma are performed laparoscopically, through several small incisions in the abdomen using a camera and long instruments. When the spleen is extremely large, the surgeon may need to convert to an open incision. Hospital stays for laparoscopic splenectomy are typically two to four days, with most people returning to light activity within two weeks and full activity within four to six weeks. One important caveat: splenectomy should generally not be performed when lymphoma has spread to lymph nodes outside the area immediately around the spleen, since removing the spleen would not address those distant sites.8Revista Brasileira de Hematologia e Hemoterapia. Splenic marginal zone lymphoma: a literature review of diagnostic and therapeutic challenges
Living Without a Spleen
The spleen filters bacteria from the bloodstream, and losing it creates a lifelong vulnerability to certain infections, particularly from encapsulated bacteria like pneumococcus, meningococcus, and Haemophilus influenzae. The risk is not trivial: patients who undergo splenectomy for a blood cancer or lymphoma face a higher infection risk than people who lose their spleen due to trauma.9PubMed. The Asplenic Patient: Post-Insult Immunocompetence, Infection, and Vaccination
Vaccination is the primary defense. When the splenectomy is planned in advance, vaccines against pneumococcus, meningococcus, Haemophilus influenzae type b, and influenza should be given at least two weeks before the operation so the immune system can mount a response while the spleen is still in place.10PubMed Central. Recommended vaccinations for asplenic and hyposplenic adult patients In emergency cases, the same vaccines are given at least two weeks after surgery. Vaccination reduces but does not eliminate the risk of overwhelming post-splenectomy infection.11PubMed Central. Bacterial Infections Following Splenectomy for Malignant and Nonmalignant Hematologic Diseases Many patients also carry a course of standby antibiotics to take at the first sign of fever while they seek medical attention, and they wear a medical alert bracelet for the rest of their lives. This lifelong vigilance is an often-underappreciated aspect of recovery from splenectomy.
Surgery for Gastrointestinal Lymphoma
Lymphoma can arise in the stomach, small intestine, or colon. When it does, the treatment picture shifts. Chemotherapy and sometimes radiation are still the backbone, but the bowel wall is thin, and a tumor lodged in it can bleed, obstruct the passage of food, or perforate. For small bowel lymphoma in particular, surgical resection of the involved segment has been associated with improved progression-free survival without a significant increase in complications.12PubMed. The role of surgical management in primary small bowel lymphoma: A single-center experience
Gastric lymphoma used to be treated primarily with surgery, but that approach has largely shifted to chemotherapy and antibiotics (for cases linked to Helicobacter pylori infection). A systematic review found that surgery for gastrointestinal lymphomas is now restricted to carefully selected situations discussed by a multidisciplinary team, and that it remains the treatment of choice when the tumor causes acute complications like perforation or uncontrollable bleeding.13PubMed Central. Surgical treatment of primitive gastro-intestinal lymphomas: a systematic review Recovery from bowel resection varies with the extent of surgery: a short segment removed with a straightforward reconnection may mean a hospital stay of five to seven days, while more extensive surgery or the creation of a temporary stoma (where the bowel is diverted to an opening in the abdomen) adds complexity and recovery time.
Emergency Surgery During Treatment
One of the more unsettling realities of lymphoma treatment is that chemotherapy itself can precipitate a surgical emergency. When a tumor in the bowel wall responds rapidly to chemotherapy and shrinks, the weakened tissue can perforate, spilling intestinal contents into the abdominal cavity. This is a life-threatening situation requiring urgent surgery. Case reports describe patients with diffuse large B-cell lymphoma developing both intestinal bleeding and perforation during treatment.14PubMed Central. Experience of serious intestinal hemorrhage and perforation in small bowel lymphoma: a case report In one case of peripheral T-cell lymphoma, a patient presented to the emergency department just two days after starting chemotherapy with sudden abdominal pain; imaging confirmed free air in the abdomen from a bowel perforation, and emergency surgery followed.15Korean Journal of Gastroenterology. Intestinal Perforation in a Case of Peripheral T Cell Lymphoma after Initiation of Chemotherapy
These emergencies often require resection of the damaged bowel segment. In another reported case, the surgical team found widespread intestinal contents in the abdomen from a perforated lesion and performed a small bowel resection; the patient was discharged on the fifth postoperative day.16PubMed Central. Intestinal perforation that developed after chemotherapy in a patient diagnosed with non-Hodgkin lymphoma: A case report and review of literature The key point for patients and families is that abdominal pain, fever, or sudden worsening during chemotherapy for GI-involved lymphoma needs immediate medical evaluation. Recovery from emergency bowel surgery is generally longer and more difficult than recovery from planned operations, because the body is fighting infection and the effects of chemotherapy simultaneously.
Spinal Cord Compression
Lymphoma occasionally grows in or around the spine and compresses the spinal cord, causing weakness, numbness, or difficulty walking. This is a neurological emergency. A systematic review of primary B-cell lymphoma of the spine found that surgical resection was performed in about 83% of patients, and symptoms improved in roughly 91% of those who had surgery, compared with 80% of those treated without an operation.17Clinical Spine Surgery. Surgical Intervention for Primary B-cell Lymphoma of the Spine: A Systematic Review and Meta-analysis of Clinical Presentation, Treatment, Postoperative Outcomes, and Histologic Markers A separate series of 17 patients who underwent decompressive surgery for spinal lymphoma reported that about two-thirds made a complete neurological recovery and none worsened after the operation.18Clinical Surgery Journal. Surgical Management of Primary Non-Hodgkin’s Lymphoma of Spine Surgery in this context serves to relieve pressure quickly and to provide tissue for diagnosis, after which chemotherapy and radiation handle the systemic disease. An earlier study noted that no patient worsened neurologically after decompressive laminectomy, though outcomes depended heavily on the degree of deficit before the operation.19PubMed.

Port Placement and Vascular Access
Most lymphoma patients need months of intravenous chemotherapy, and repeated needle sticks into arm veins become painful and impractical. A minor surgical procedure to place a vascular access device solves this. The two main options are an implanted port (a small disc placed under the skin of the upper chest, connected to a catheter threaded into a large vein) and a peripherally inserted central catheter, or PICC line, threaded through an arm vein.
Port placement takes about 30 to 60 minutes, usually under local anesthesia with sedation. The incision is small, and most people go home the same day. The port sits under the skin and is accessed by a special needle during treatment sessions, then left alone between cycles. A study of patients with diffuse large B-cell lymphoma found that PICCs carried roughly 2.6 times the risk of catheter-related complications compared with implanted ports, with significantly higher rates of both infection and blood clots.20PubMed Central. Retrospective analysis of the safety of peripherally inserted catheters versus implanted port catheters during first-line treatment for patients with diffuse large B-cell lymphoma A meta-analysis across cancer types echoed this, finding external catheters associated with roughly three to four times the risk of infections and device removal compared with implanted ports.21PubMed. Centrally inserted external catheters and totally implantable ports for the delivery of chemotherapy: a systematic review and meta-analysis of device-related complications
That said, ports are not trouble-free. In one series, about a quarter of ports were removed prematurely, most often because of infection, with Staphylococcus aureus being the most common culprit.22Journal of Infection in Developing Countries. Use of port-a-cath in cancer patients: a single-center experience Port removal itself is a brief outpatient procedure. Most patients say the port was well worth the minor surgery, since it spares months of difficult IV access.
Recovery Challenges Unique to Lymphoma Patients
Recovering from any surgery while undergoing cancer treatment is harder than recovering from surgery alone. Lymphoma patients face some specific obstacles. Many chemotherapy regimens for lymphoma include corticosteroids like prednisone or dexamethasone, which are effective against the disease but impair wound healing. Steroids reduce the body’s inflammatory response, slow collagen deposition, and can produce fragile wounds prone to breaking open.23PubMed Central. Wound healing in cancer patients under immunotherapy Research has long established that corticosteroids weaken the mechanical strength of healing tissue, reducing its ability to withstand normal forces.24PubMed Central. Reconstructive surgery in immunocompromised patients: evaluation and therapy
Chemotherapy itself often drives down white blood cell counts, raising infection risk during the recovery window. Surgical teams coordinate closely with oncologists to time procedures during periods when blood counts are expected to be at their highest. For advanced Burkitt lymphoma in children, for example, a study found that performing a laparotomy delayed the start of chemotherapy by an average of nine days and extended total hospital stay, with concern that this delay could reduce survival in a disease where rapid initiation of chemotherapy is critical.25PubMed. Initial management of advanced Burkitt lymphoma in children: is there still a place for surgery? This tension between needing surgery and needing to start or continue chemotherapy runs through many lymphoma treatment decisions.
Lymphatic damage is another complication that can emerge during or after treatment. In one case, chemotherapy shrank a large abdominal lymphoma but damaged the surrounding lymphatic vessels, producing persistent chylous ascites, a milky fluid buildup in the abdomen that required frequent drainage. The leak was ultimately identified and sealed using a specialized imaging and treatment procedure involving lymphangiography.26PubMed Central. Effective Intractable Chylous Ascites Treatment by Lymphangiography with Lipiodol in a Patient with Follicular Lymphoma This is uncommon but illustrates how the interplay between tumor shrinkage and surrounding tissue can create unexpected surgical problems.
Biopsies at Relapse
If lymphoma comes back or stops responding to treatment, a repeat biopsy is often needed before changing therapies. Lymphoma can transform from an indolent (slow-growing) type into an aggressive one over time, and the only way to know is to look at the tissue. In one series, among 80 biopsies taken at the time of recurrence or progression, the tissue showed a change in the type of lymphoma in 33 cases, and in 31 of those 33, the finding directly altered the treatment plan.27PubMed. Role of image-guided core-needle biopsy in the management of patients with lymphoma This is why oncologists do not simply restart the same chemotherapy when lymphoma returns; confirming what the disease looks like now, not what it looked like at diagnosis, changes the approach in a meaningful fraction of cases.
When disease recurs in the mediastinum (the central compartment of the chest), a residual mass on imaging may represent scar tissue or active lymphoma. Minimally invasive thoracoscopic surgery, using video-assisted or robotic-assisted techniques, can sample these masses without requiring a large chest incision.28PubMed Central. Utility of minimally-invasive thoracoscopy for assessment of residual mediastinal lymphoma Recovery from these camera-guided chest procedures is faster than from open thoracotomy, with most patients leaving the hospital within a day or two.
Pediatric Considerations
Children with lymphoma present particular surgical challenges, especially when a large mass sits in the front of the chest (the anterior mediastinum). These masses can compress the airway or the major veins draining the head and arms, and administering general anesthesia to a child whose airway is already partially squeezed is high-risk. Reports describe children developing laryngospasm or oxygen desaturation during anesthesia induction for biopsy of anterior mediastinal masses.29BMJ. Association of anesthetic and surgical risk factors with outcomes of initial diagnostic biopsies in a current cohort of children with anterior mediastinal masses Anesthesiologists in these cases plan carefully, often positioning the child on their side rather than flat on their back, and maintaining spontaneous breathing rather than using muscle relaxants that could cause the airway to collapse under the weight of the mass. When the airway risk is too high, some centers start a brief course of steroids to shrink the mass before attempting biopsy, accepting the small risk that steroids might complicate the tissue diagnosis.
Tumor Debulking Before CAR T-Cell Therapy
An emerging area where surgery may carve out a new role is in preparing patients for CAR T-cell therapy, a treatment where a patient’s own immune cells are engineered in a lab to attack lymphoma cells and then infused back. One challenge with CAR T-cell therapy is that patients with a very high tumor burden tend to respond less well; the sheer number of lymphoma cells can overwhelm the engineered T cells. A pharmacologic modeling study predicted that reducing tumor burden before infusion could improve the rate of durable remission, essentially suggesting that the ratio of lymphoma cells to CAR T cells is itself a mechanism of resistance.30PubMed Central. A Pharmacologic Model Predicts that Tumor Debulking Improves CAR T-cell Efficacy in Large B-cell Lymphoma This idea is still in early stages, and debulking could take the form of radiation or chemotherapy rather than surgery. But in selected patients with a single dominant mass, surgical debulking could theoretically improve the odds that CAR T cells succeed.
Long-Term Function and Quality of Life
Recovery from lymphoma-related surgery does not end when the incision heals. Many patients contend with fatigue, deconditioning from months of treatment, and the psychological toll of a cancer diagnosis. A study of non-Hodgkin lymphoma patients found that most achieved good functional recovery and reported satisfaction with their lives after treatment, though the path to that outcome varied widely depending on the type and intensity of treatment received.31PubMed Central. Factors Associated with Long-Term Functional and Psychosocial Outcomes in Patients with Non-Hodgkin Lymphoma Rehabilitation, including graded exercise programs and psychological support, plays a real part in recovery. For patients who have undergone splenectomy, the added mental load of lifelong infection vigilance is something that takes adjustment. For those with stomas after bowel surgery, learning to manage the device and eventually having it reversed adds months to the recovery timeline. The specifics depend heavily on which surgery was performed and what other treatments surrounded it, but the general trajectory for most lymphoma patients who require surgery is a return to normal daily function within weeks to months of the procedure itself.
