Cancer Surgery: A Complete Patient and Family Guide

At a glance: Surgery is one of the main treatments for cancer. It is most effective when a solid tumor is limited to an area that a surgeon can safely reach and remove. Surgery may be the only treatment needed, but it is often combined with chemotherapy, radiation therapy, immunotherapy, targeted therapy, or hormone therapy.

Important: This page provides general education and does not determine whether surgery is appropriate for a particular person. Surgical recommendations depend on the cancer type, stage, location, pathology, overall health, treatment goals, and the judgment of a qualified multidisciplinary cancer team.

Personalized-care reminder: Two people with the same general cancer diagnosis may receive different surgical recommendations. Ask your oncology team to explain why a particular operation is—or is not—recommended for your individual situation.

Cancer surgery is a medical procedure used to remove, examine, destroy, repair, or reconstruct tissue affected by cancer. It is performed by a surgeon with training appropriate to the organ, body system, or cancer being treated.

A surgical oncologist is a surgeon with specialized training in cancer surgery. Depending on the cancer, an operation may also be performed by a breast surgeon, colorectal surgeon, gynecologic oncologist, neurosurgeon, orthopedic oncologist, thoracic surgeon, urologic oncologist, head and neck surgeon, pediatric surgeon, plastic and reconstructive surgeon, or another appropriately trained specialist.

Surgery is considered a local treatment because it treats a particular area of the body. By comparison, systemic treatments such as chemotherapy, many targeted therapies, hormone therapy, and immunotherapy can circulate throughout the body.

According to the National Cancer Institute, surgery works best for many solid tumors that are contained in one area. It is generally not the primary way to remove cancers involving cells throughout the blood or bone marrow, such as leukemia.

Important distinction: Surgery can sometimes be used even when cancer has spread, particularly to relieve symptoms or, in carefully selected cases, to remove a limited number of metastatic tumors. However, widespread cancer usually requires treatment that can reach cancer cells throughout the body.

1. Diagnostic Surgery or Biopsy

A biopsy removes cells or tissue so that a pathologist can examine them. An incisional biopsy removes part of an abnormal area, while an excisional biopsy removes the entire visible abnormal area. Many biopsies are performed with needles or image-guided techniques rather than an open operation.

2. Staging Surgery

Staging describes the size and extent of cancer and whether it has reached nearby lymph nodes or distant organs. Surgery may provide information that imaging alone cannot provide. Tissue removed during an operation is examined by a pathologist and may affect the final cancer stage and treatment plan.

3. Curative or Primary Surgery

The goal is to remove all detectable cancer, usually with a surrounding border of normal-looking tissue. Curative surgery is most likely to be considered when the cancer appears localized and can be removed without causing unacceptable harm.

4. Debulking or Cytoreductive Surgery

Debulking removes as much cancer as safely possible when removing every visible area would be impossible or could seriously damage an organ. Reducing the amount of cancer may help other treatments work more effectively. Cytoreductive surgery is used in selected cancers, including certain ovarian, abdominal, and other malignancies.

5. Palliative Surgery

Palliative surgery is intended to relieve symptoms and improve comfort or function rather than eliminate all cancer. It may be used to bypass a blockage, reduce pressure on a nerve, control bleeding, stabilize a weakened bone, improve breathing, or help a person eat.

6. Supportive Surgery

Supportive procedures make other treatments safer or easier to deliver. Examples include placing an implanted port or central venous catheter for chemotherapy, inserting a feeding tube, or creating another form of treatment access.

7. Reconstructive Surgery

Reconstructive surgery repairs or rebuilds an area affected by cancer or its treatment. It may restore appearance, movement, speech, swallowing, urinary function, or another body function. Reconstruction may be performed during the cancer operation or at a later time.

8. Preventive or Risk-Reducing Surgery

Risk-reducing surgery removes tissue that has a particularly high likelihood of developing cancer. It may be considered for some people with strongly inherited cancer risks or particular precancerous conditions. It reduces risk but does not guarantee that cancer will never occur.

Surgery may be considered when one or more of the following apply:

• The cancer is a solid tumor that appears limited to one region.
• The tumor can be reached and removed with an acceptable level of risk.
• Surgery offers a reasonable possibility of cure or long-term cancer control.
• A tissue sample is needed to establish or confirm the diagnosis.
• Removing lymph nodes or other tissue will provide important staging information.
• Reducing the tumor could improve the effectiveness of other treatments.
• The tumor is causing pain, bleeding, pressure, obstruction, breathing problems, or another serious symptom.
• Reconstruction could restore appearance or physical function.
• A high-risk inherited condition makes risk-reducing surgery medically appropriate.

Surgery may not be the safest or most effective treatment when:

• Cancer is widely distributed throughout the body.
• The cancer involves the blood, bone marrow, or lymphatic system in a way that cannot be removed as one mass.
• The tumor is wrapped around or invading structures that cannot be safely removed.
• Removing the tumor would cause more harm than expected benefit.
• The person’s heart, lungs, kidneys, liver, nutrition, or overall health makes major surgery excessively risky.
• Radiation, systemic therapy, active surveillance, or another treatment is expected to provide equal or better cancer control.
• The tumor should first be reduced with chemotherapy, radiation, targeted therapy, immunotherapy, or another treatment.
• The likely benefits do not match the person’s goals, priorities, or acceptable quality of life.

A recommendation against surgery does not necessarily mean that no effective treatment is available. It may mean that another form of treatment is more likely to help.

• Operable: The person is considered medically able to undergo the proposed operation.
• Resectable: The cancer appears capable of being completely removed using surgery.
• Borderline resectable: Complete removal may be possible, but the cancer is close to important structures. Treatment may be given first to improve the possibility of successful surgery.
• Unresectable: The cancer cannot currently be removed completely or safely.

These terms can change during treatment. A tumor considered unresectable at diagnosis may sometimes become resectable after an effective response to treatment. In other cases, an operation may reveal more extensive disease than imaging showed.

Cancer operations may be described according to how much tissue is removed:

• Local excision: Removes the tumor and a small amount of surrounding tissue.
• Wide local excision: Removes the tumor with a wider margin of surrounding tissue.
• Partial resection: Removes the cancer-containing part of an organ.
• Total resection: Removes an entire organ or body structure.
• Radical resection: Removes the tumor, surrounding tissue, and sometimes nearby lymph nodes or associated structures according to the operation required.
• En bloc resection: Removes a tumor and directly involved nearby structures together as one specimen when medically appropriate.
• Organ-sparing surgery: Removes cancer while preserving as much healthy tissue and function as safely possible.
• Salvage surgery: May be considered when cancer remains or returns after another treatment.
• Metastasectomy: Removes one or more metastatic tumors in carefully selected patients.
• Re-excision: Removes additional tissue after an initial operation, often because cancer cells were found at or near a surgical margin.

Open Surgery

Open surgery uses an incision large enough for the surgeon to directly reach the affected area. It may provide the safest access to large, complex, or difficult-to-reach tumors and may be necessary when several organs or major blood vessels are involved. Recovery may take longer than with a less invasive approach.

Laparoscopic Surgery

Laparoscopic surgery uses several small incisions. A thin instrument containing a camera sends images to a monitor, and specialized instruments are placed through other openings. When appropriate, this approach may reduce pain, blood loss, hospital time, and recovery time compared with open surgery.

Thoracoscopic Surgery

Thoracoscopic surgery uses a camera and instruments placed through small openings in the chest. Video-assisted thoracic surgery, commonly called VATS, may be used for selected lung, chest, and mediastinal procedures.

Robotic-Assisted Surgery

Robot-assisted surgery is a form of computer-assisted minimally invasive surgery. The surgeon controls the instruments from a console. The system does not independently decide what to cut or perform the operation without the surgeon.

Robotic systems can provide magnified views and instruments capable of precise movements in confined spaces. However, robotic surgery is not automatically the best approach for every cancer.

The most important question is not simply whether a robot is used, but whether the proposed operation can be performed safely, completely, and according to accepted cancer-surgery principles by a team experienced with that procedure. See the FDA’s information on computer-assisted surgical systems.

Choosing a technique: Smaller incisions can offer recovery advantages, but they are not appropriate for every tumor. Open surgery may be the safer or more effective approach for some cancers. Surgeon experience and cancer outcomes matter more than the name of the technology.

Endoscopic Surgery

An endoscope is passed through a natural body opening, such as the mouth, nose, urinary tract, or rectum. Certain early or superficial tumors can be removed without a traditional external incision.

Mohs Surgery

Mohs surgery removes thin layers of skin one at a time. Each layer is examined until no cancer cells remain at the checked edges. It is commonly used for selected skin cancers, particularly where preserving healthy tissue is important.

Microsurgery

Microsurgery uses magnification and very small instruments. It may be used in delicate operations and in reconstruction involving small blood vessels, nerves, or tissue flaps.

Laser Surgery

Laser treatment uses a focused beam of light to cut, remove, or destroy abnormal tissue. It may be used for selected surface tumors, precancerous changes, tumors lining certain internal organs, or symptom relief. Learn more from the National Cancer Institute’s laser-treatment guide.

Cryosurgery or Cryoablation

Cryosurgery uses extreme cold to freeze and destroy abnormal tissue. It may be used for selected skin, cervical, prostate, liver, bone, eye, and other tumors or precancerous conditions. See the NCI guide to cryosurgery.

Electrosurgery

Electrosurgery uses electrical current to cut tissue or destroy abnormal cells. It may be used for selected skin, cervical, and other superficial abnormalities.

Radiofrequency or Microwave Ablation

Ablation uses heat delivered through a probe to destroy selected tumors. These procedures may be performed by surgeons or interventional radiologists and are commonly considered for certain liver, kidney, lung, bone, or other tumors.

Photodynamic Therapy

Photodynamic therapy combines a light-sensitive medicine with a particular type of light. It is used for selected cancers and precancerous conditions near the skin or the lining of organs. Although it may appear alongside surgical treatments, it is a distinct local treatment technique.

Terminology note: “Stereotactic radiosurgery” is actually a highly precise form of radiation therapy. It does not involve an incision and is not conventional surgery.

What Is a Surgical Margin?

A surgical margin is the edge of tissue around a removed tumor. The surgeon usually removes some normal-looking tissue around the cancer to increase the likelihood that the entire tumor has been removed.

• Negative or clear margin: No cancer cells are seen at the examined edge.
• Positive or involved margin: Cancer cells are present at the edge.
• Close margin: Cancer cells are near the edge, based on the definitions used for that cancer type.

A positive or close margin does not lead to the same recommendation in every cancer. The team may recommend another operation, radiation therapy, systemic treatment, close observation, or a combination based on the cancer type and circumstances.

Why Are Lymph Nodes Examined?

Lymph nodes are small immune-system structures. Many solid cancers can first spread to nearby regional lymph nodes. Removing or sampling selected nodes may help determine the stage and guide additional treatment.

• Sentinel lymph-node biopsy: Identifies and removes the first node or group of nodes most likely to receive drainage from a tumor.
• Lymph-node sampling: Removes selected nodes for examination.
• Lymph-node dissection: Removes a larger group of regional lymph nodes when medically indicated.

What the Pathologist Examines

The pathology report may describe:

• The exact cancer type and subtype
• Tumor size and location
• Grade or cellular features
• Depth of invasion
• Margin status
• Blood-vessel, lymphatic, nerve, or nearby-organ involvement
• The number of lymph nodes examined and the number containing cancer
• Biomarkers or molecular findings relevant to treatment
• The pathologic stage, when applicable

Confirm the Treatment Plan

• Ask for the exact name and purpose of the operation.
• Understand whether the goal is diagnosis, cure, control, symptom relief, prevention, or reconstruction.
• Ask whether other treatments are needed before or after surgery.
• Ask what may change the surgical plan once the operation begins.
• Discuss whether a second opinion would be helpful.

Preoperative Assessment

The surgical team may order or review:

• Blood and urine tests
• Imaging studies
• An electrocardiogram or heart evaluation
• Tests of lung function
• Nutritional assessment
• Medication and allergy review
• Evaluation of diabetes, sleep apnea, bleeding risk, or other health conditions
• An anesthesia consultation

Review Every Medicine and Supplement

Give the team a complete list of prescription medicines, nonprescription medicines, vitamins, herbs, supplements, cannabis products, and other substances you use. Some products may affect bleeding, blood pressure, anesthesia, or healing. Do not stop a prescribed medicine—especially a blood thinner, heart medicine, seizure medicine, steroid, insulin, or diabetes treatment—unless the prescribing clinician and surgical team tell you how to manage it.

Nutrition and Physical Preparation

Major surgery increases the body’s nutritional needs. Tell your team about unplanned weight loss, poor appetite, swallowing problems, vomiting, diarrhea, or difficulty obtaining food. An oncology dietitian may recommend protein, calories, supplements, or another nutrition plan. Some patients also benefit from supervised activity, breathing exercises, or prehabilitation before surgery.

Discuss Smoking and Alcohol Honestly

Tell the anesthesia and surgical teams about tobacco, vaping, alcohol, and substance use. This information is used for safety, anesthesia planning, withdrawal prevention, breathing support, and wound-healing decisions—not judgment.

Fertility, Sexual Health and Hormonal Effects

Some operations can affect fertility, sexual function, menstruation, hormone production, pregnancy, urinary function, or body image. Ask about these effects before treatment whenever possible. Fertility-preservation discussions may need to occur before surgery or other cancer treatment begins.

Plan for Home and Work

• Arrange transportation because driving may be restricted.
• Ask how much assistance you may need at home.
• Plan for child care, pet care, meals, medications, stairs, and wound supplies.
• Ask about work leave, lifting restrictions, school, and disability paperwork.
• Identify the daytime and after-hours phone numbers for the surgical team.
• Ask whether home nursing, rehabilitation, or medical equipment will be needed.

Follow fasting instructions exactly: Your team will tell you when to stop eating and drinking. These instructions may differ according to the operation, anesthesia plan, and medical conditions. Failure to follow them can make anesthesia unsafe and may cause the operation to be delayed.

Anesthesia prevents or controls pain during a procedure. The appropriate type depends on the operation, its location and duration, and the person’s health.

• Local anesthesia: Numbs a small area while the person remains awake.
• Regional anesthesia: Numbs a larger region of the body, sometimes with additional sedation.
• General anesthesia: Produces a controlled state of unconsciousness for major surgery.
• Sedation: Reduces anxiety and awareness and may range from light to deep.

The anesthesia team reviews medical conditions, allergies, past anesthesia experiences, airway concerns, medicines, and recent food or fluid intake. Tell the team about previous severe nausea, difficult intubation, sleep apnea, loose teeth, implanted devices, or family reactions to anesthesia.

Ask how pain and nausea will be prevented and managed. Pain control may include several approaches, such as non-opioid medicines, limited opioid treatment, local anesthetic, epidural medicine, or nerve blocks.

Before the Operation

• Your identity, procedure, allergies, and consent will be verified.
• The team may mark the surgical site.
• An intravenous line may be placed.
• Preventive antibiotics or blood-clot prevention may be given when indicated.
• You will meet members of the surgery and anesthesia teams.
• The team will perform safety checks before beginning.

During the Operation

The surgeon removes or treats the planned tissue. Depending on the operation, nearby tissue, lymph nodes, or involved structures may also be removed. Some tissue may be examined during the operation, but the complete pathology evaluation usually occurs afterward.

Immediately Afterward

You will usually go to a post-anesthesia recovery area. Staff monitor breathing, blood pressure, heart rate, oxygen level, pain, nausea, bleeding, and alertness. Depending on the procedure and health needs, you may go home, stay in a hospital room, or receive care in an intensive or higher-monitoring unit.

Pain Control

Some pain or soreness is expected after many operations, but uncontrolled pain should be reported. Effective pain management can help you breathe deeply, sleep, move, and participate in rehabilitation.

Early Movement

When the team says it is safe, sitting up, standing, and walking can support circulation, bowel function, lung expansion, and recovery. Ask for assistance before getting up if you feel weak or dizzy.

Breathing Exercises

Deep-breathing exercises, coughing techniques, or an incentive spirometer may be recommended to help expand the lungs and reduce postoperative breathing complications.

Eating and Drinking

Diet progression depends on the operation. Some people can eat soon afterward, while others need liquids, tube feeding, or intravenous nutrition temporarily. Report persistent nausea, vomiting, swallowing difficulty, or inability to eat or drink.

Incisions, Dressings and Drains

Follow the written instructions for bathing, dressing changes, staples, stitches, drains, and activity. Do not apply creams, disinfectants, herbal products, powders, or home remedies to the incision unless the surgical team approves them.

Activity Restrictions

Restrictions may apply to lifting, driving, exercise, work, sexual activity, bathing, swimming, and travel. Ask for specific instructions and do not use pain improvement alone as proof that internal healing is complete.

Recovery Is Individual

Recovery time varies according to the procedure, age, health, nutrition, complications, home support, and additional treatment. Compare your progress with the plan your team provided rather than with another patient’s experience.

Every operation has possible risks. The type and likelihood depend on the location and extent of surgery, anesthesia, medical conditions, age, and other individual factors.

• Pain or persistent nerve-related discomfort
• Bleeding, bruising, or need for transfusion
• Infection
• Reactions to anesthesia or medicines
• Blood clots in the legs or lungs
• Breathing complications or pneumonia
• Damage to nearby organs, nerves, blood vessels, or tissues
• Delayed wound healing or separation of the incision
• Fluid collections, swelling, or lymphatic complications
• Lymphedema after certain lymph-node procedures
• Changes in bowel, bladder, sexual, hormonal, or reproductive function
• Numbness, weakness, reduced mobility, or altered sensation
• Scarring or changes in physical appearance
• Need for temporary or permanent drains, catheters, feeding tubes, breathing openings, or ostomies
• Need for another procedure
• Incomplete removal of the cancer
• Rare life-threatening complications

Ask for personalized numbers: General complication lists do not show your personal risk. Ask the surgeon about the most important risks for the exact operation, the team’s experience, how complications are prevented, and what would happen if one occurred.

Follow the discharge instructions provided by your own team. Contact the surgical team promptly for symptoms they identified or for concerns such as:

• A fever at or above the level your team told you to report
• Shaking chills
• Increasing redness, warmth, swelling, drainage, odor, or opening of an incision
• Bleeding that does not stop or rapidly increasing bruising
• Pain that is worsening or not controlled by the recommended plan
• Persistent vomiting or inability to keep fluids down
• New trouble urinating or major changes in bowel function
• A drain that suddenly stops, falls out, changes substantially, or has unexpected output
• New leg swelling or unusual calf pain
• New confusion, severe weakness, fainting, or concerning dizziness
• Any new symptom specifically listed in your discharge instructions

Seek emergency medical care for severe trouble breathing, chest pain, uncontrolled bleeding, loss of consciousness, signs of stroke, or another immediately life-threatening symptom.

Neoadjuvant Treatment

Neoadjuvant treatment is given before surgery. It may shrink a tumor, treat cancer cells beyond the visible tumor, make an operation safer, increase the chance of preserving an organ, or show how the cancer responds to treatment. It may include chemotherapy, radiation, targeted therapy, immunotherapy, hormone therapy, or a combination.

Adjuvant Treatment

Adjuvant treatment is given after surgery to reduce the chance that cancer will return by treating cancer cells that may remain but are too small to detect. Recommendations are based on pathology, stage, margins, lymph nodes, biomarkers, overall health, and expected benefit.

Intraoperative Treatment

Some centers provide specialized treatment during an operation, such as intraoperative radiation, heated chemotherapy placed into a body cavity, fluorescence-guided imaging, or other tumor-directed techniques. These approaches are appropriate only for selected cancers and patients.

Multidisciplinary Care

Cancer surgery is frequently one part of a larger plan involving medical oncologists, radiation oncologists, pathologists, radiologists, genetic specialists, oncology nurses, rehabilitation professionals, dietitians, pharmacists, palliative-care clinicians, and psychosocial-support professionals.

The following examples are general. Each cancer has multiple stages, subtypes, and surgical options.

• Breast cancer: Lumpectomy, mastectomy, lymph-node procedures, and reconstruction.
• Colorectal cancer: Removal of a section of colon or rectum, sometimes with a temporary or permanent ostomy.
• Lung cancer: Wedge resection, segmentectomy, lobectomy, or removal of a larger lung section in selected patients.
• Prostate cancer: Radical prostatectomy for selected localized cancers.
• Kidney cancer: Partial nephrectomy or removal of the kidney, depending on the tumor and circumstances.
• Bladder cancer: Endoscopic tumor removal or partial or complete bladder removal for selected disease.
• Gynecologic cancers: Procedures involving the cervix, uterus, ovaries, fallopian tubes, lymph nodes, or surrounding tissue.
• Melanoma and other skin cancers: Local excision, wide excision, Mohs surgery for selected tumors, and possible lymph-node evaluation.
• Head and neck cancers: Tumor removal with possible lymph-node surgery and reconstruction.
• Thyroid cancer: Removal of part or all of the thyroid, with lymph-node surgery when indicated.
• Brain and spinal tumors: Biopsy, partial removal, or maximal safe removal, depending on location and neurologic risk.
• Liver cancer: Partial liver resection or transplantation in carefully selected patients; ablation may be considered in others.
• Pancreatic cancer: Complex operations for selected tumors that appear removable.
• Stomach or esophageal cancer: Removal of part or all of the affected organ, often combined with chemotherapy or radiation.
• Bone and soft-tissue sarcomas: Wide removal, often using limb-sparing and reconstructive techniques when possible.
• Pediatric solid tumors: Surgery may be combined with chemotherapy, radiation, or other specialized pediatric treatment.

Cancer surgery can affect appearance, mobility, speech, swallowing, breathing, digestion, bladder control, sexual function, fertility, sensation, or independence. Planning for these possibilities is part of high-quality cancer care.

Reconstruction may involve:

• Implants or prosthetic devices
• Skin, muscle, fat, or bone transferred from another area
• Microsurgical tissue-flap procedures
• Breast reconstruction
• Jaw, facial, limb, urinary, or digestive reconstruction
• Creation or reversal of an ostomy
• Dental, speech, swallowing, or hearing rehabilitation

Rehabilitation may include:

• Physical therapy
• Occupational therapy
• Speech and swallowing therapy
• Pelvic-floor therapy
• Lymphedema education and treatment
• Respiratory therapy
• Nutrition therapy
• Sexual-health and fertility support
• Prosthetic and mobility services
• Emotional and body-image counseling

Supportive and integrative services may help with anxiety, pain, nausea, sleep, mobility, fatigue, and emotional well-being. They are intended to support—not replace—evidence-based cancer treatment.

Depending on medical approval and the stage of recovery, supportive care may include:

• Oncology nutrition counseling
• Physical and occupational therapy
• Gentle supervised movement
• Breathing and relaxation practices
• Mindfulness or meditation
• Psychological counseling
• Spiritual care based on personal preference
• Massage or acupuncture when cleared by the surgical and oncology teams
• Palliative care for symptom management at any stage of serious illness

Do not begin herbs, high-dose vitamins, restrictive diets, detox programs, fasting regimens, topical products, or alternative treatments without discussing them with the cancer team. Some can affect anesthesia, bleeding, nutrition, medicines, wound healing, or treatment effectiveness.

Myth: A biopsy or operation automatically causes cancer to spread.

Fact: Biopsies and cancer operations are planned using techniques intended to avoid spreading cancer. The benefits of obtaining an accurate diagnosis or removing a tumor generally outweigh this concern when the procedure is medically recommended.

Myth: Surgery is needed for every cancer.

Fact: Some cancers are treated mainly with medicines, radiation, active surveillance, stem-cell transplantation, or other approaches.

Myth: Minimally invasive surgery is always better than open surgery.

Fact: The best approach is the one most likely to remove or treat the cancer safely while preserving appropriate function. Open surgery remains necessary for many complex operations.

Myth: A surgical robot performs the operation by itself.

Fact: Robot-assisted systems are controlled by trained surgeons.

Myth: Clear margins guarantee that cancer can never return.

Fact: Clear margins are important, but recurrence risk also depends on cancer biology, stage, lymph-node findings, biomarkers, and possible microscopic disease elsewhere.

Myth: Palliative surgery means the medical team has stopped treating the patient.

Fact: Palliative surgery is active treatment intended to relieve symptoms, maintain function, prevent complications, or improve quality of life.

Myth: Natural products are always safe before and after surgery.

Fact: Supplements and herbal products can affect bleeding, anesthesia, medicines, nutrition, or healing. The surgical team needs a complete list.

A second opinion can confirm the plan, identify alternatives, clarify whether an organ-sparing or minimally invasive approach is appropriate, or provide access to a team with greater experience in a rare or complex operation.

A second opinion may be especially valuable when:

• The cancer is rare.
• The operation is highly complex.
• The proposed surgery could cause major permanent changes.
• Doctors disagree about whether the tumor is removable.
• Several treatment sequences are reasonable.
• You want information about reconstruction, organ preservation, or clinical trials.
• You are uncomfortable with or do not fully understand the recommendation.

Ask whether the new center needs:

• Pathology slides or tissue blocks
• Imaging files, not only written reports
• Operative reports from previous procedures
• Laboratory and molecular-test results
• A treatment summary and medication list

Find centers through the NCI-Designated Cancer Centers directory.

Clinical trials study new operations, imaging methods, technologies, treatment combinations, recovery pathways, and strategies intended to reduce complications or preserve function.

Questions to ask include:

• What is the trial designed to learn?
• How does the study treatment differ from standard care?
• Will surgery be delayed or changed?
• What are the known and uncertain risks?
• What extra visits, tests, costs, or travel are involved?
• What happens if I choose not to participate?

Search through the National Cancer Institute Clinical Trials Search. Trial eligibility must be reviewed by the research team and your treating clinicians.

Cancer-surgery costs may include separate charges for the surgeon, assistant surgeon, anesthesiologist, hospital or facility, pathology, imaging, medicines, implants, reconstruction, rehabilitation, home care, equipment, and follow-up.

Before surgery, consider asking:

• Are the surgeon, anesthesiologist, hospital, pathologist, and other clinicians in network?
• Is prior authorization required?
• What deductible, coinsurance, or copayment may apply?
• Are reconstruction and rehabilitation covered?
• Will home nursing, ostomy supplies, drains, or medical equipment be needed?
• Is travel or temporary lodging necessary?
• Is a financial navigator or social worker available?
• Does the hospital offer payment assistance, charity care, or a payment plan?

Cancer surgery is not one single treatment. It includes procedures used to establish a diagnosis, determine a stage, remove localized cancer, reduce tumor burden, relieve symptoms, prevent cancer in people at very high risk, and restore function or appearance.

The best operation is not necessarily the newest, largest, smallest, or most technologically advanced procedure. It is the procedure most likely to meet the patient’s treatment goals while balancing cancer control, safety, quality of life, long-term function, and personal preferences.

Patients and families deserve understandable explanations, access to qualified specialists, appropriate second opinions, realistic discussions of risks and benefits, strong recovery support, and a clear plan for what happens after pathology results are available.
