Not every cancer patient needs surgery, and finding a tumor that can be removed does not necessarily mean that surgery should be the first step in treatment. In some cases, it may be preferable to begin with chemotherapy or radiation therapy and then reassess the tumor before making a surgical decision.
A surgical oncologist works as part of a multidisciplinary team that includes medical oncologists, radiation oncologists, radiologists, and pathologists. The goal is to determine whether the tumor can be removed, the extent of surgery required, and the most appropriate timing of the operation within the overall cancer treatment plan.
Tabibak Healthcare helps international patients submit biopsy reports, medical imaging, and previous medical records to the appropriate doctor and medical center in Turkey to obtain an initial evaluation before arranging travel.
Overview of Surgical Oncology
Surgical oncology primarily focuses on solid tumors that can be accessed surgically. The purpose of surgery may be to remove the tumor completely, obtain a tissue sample for diagnosis, reduce the size of the tumor, assess lymph nodes, or relieve symptoms caused by the tumor.
Surgery may be performed using open surgery, laparoscopic techniques, or robotic surgical systems when appropriate. The choice depends on the type, location, and stage of the cancer, as well as the patient’s overall health, rather than simply on the availability of a particular technology.
The National Cancer Institute explains that surgery is generally most effective for solid tumors confined to a specific area and is often used as part of a treatment plan that combines several types of cancer therapy.
What Is Surgical Oncology?
Surgical Oncology is the medical field that uses surgery to diagnose and treat tumors and to manage certain complications caused by cancer.
The role of a surgical oncologist is not limited to removing a cancerous mass. It may include performing a biopsy, assessing whether a tumor can be removed, removing affected tissue with an appropriate surgical margin, examining or removing lymph nodes, performing organ-preserving surgery, or collaborating with plastic and reconstructive surgery when reconstruction is required after tumor removal.
The type of surgeon involved also depends on the affected organ. Lung cancer may require a thoracic surgeon, ovarian cancer may require a gynecologic oncologist, and kidney cancer may require a urologic surgeon. Surgical oncologists and general surgeons manage many tumors involving the gastrointestinal tract, liver, pancreas, and breast.
What Is the Difference Between a Surgical Oncologist and a Medical Oncologist?
Oncology is not a single specialty. Several doctors may participate in a patient’s cancer treatment, each with a different role.
- A surgical oncologist manages the surgical aspects of cancer diagnosis and treatment, such as tumor removal, lymph node surgery, and biopsies.
- A medical oncologist uses medication-based treatments, including chemotherapy, targeted therapy, immunotherapy, and hormonal therapy when appropriate for the type of cancer.
- A radiation oncologist plans radiation therapy for cancers that may benefit from this form of treatment.
For this reason, a patient may consult three or more specialists before a treatment plan is finalized. Being referred to a surgical oncologist does not necessarily mean that surgery will be required.
When Does a Cancer Patient Need Evaluation by a Surgical Oncologist?
A surgical evaluation is important when a solid tumor is discovered that may potentially be resectable, or when the medical team needs to determine whether surgery is possible after reviewing the biopsy and imaging studies.
A consultation may also be necessary before major surgery involving removal of an entire organ, after cancer recurrence, when there are differences between proposed treatment plans, or when a patient has been told that the tumor is unresectable and wishes to obtain a second opinion from a specialized center.
In some cases, the purpose of surgery is not to remove the cancer completely, but rather to manage a problem caused by the tumor, such as intestinal obstruction, pressure on an organ, or bleeding.
Can All Types of Cancer Be Treated With Surgery?
No. Surgery is a local treatment, which means it is most commonly associated with solid tumors that can be identified and surgically accessed.
Blood cancers such as leukemia do not involve a localized tumor that can be surgically removed, so surgery is not their primary treatment. Surgery may also be unsuitable in some cases of widely metastatic cancer unless it serves a specific purpose, such as relieving symptoms or treating selected metastatic sites under certain circumstances.
Therefore, the key question is not simply, “Can the tumor be removed?” A more appropriate question is: Will surgery provide a meaningful benefit within this patient’s overall treatment plan?
Cancers That May Fall Within the Scope of Surgical Oncology
| Type of Cancer | Examples | Potential Role of Surgery |
|---|---|---|
| Gastrointestinal Cancers | Stomach, colon, rectal, pancreatic, and intestinal cancers | Removal of the tumor and the affected part of the organ, with the extent of surgery determined according to the stage and the tumor’s relationship with surrounding organs and blood vessels. |
| Liver, Gallbladder, and Bile Duct Tumors | Liver cancer, gallbladder tumors, bile duct tumors, and selected liver metastases | Removal of part of the liver, gallbladder, or bile ducts in operable cases after evaluating liver function and major blood vessels. |
| Breast Tumors | Localized breast cancer and other resectable breast tumors | Breast-conserving surgery or mastectomy, with lymph node evaluation and reconstruction when required. |
| Endocrine Tumors | Thyroid cancer, parathyroid tumors, adrenal tumors, and selected neuroendocrine tumors | Removal of the tumor, part of the gland, or the entire gland depending on the type, size, and characteristics of the tumor. |
| Gynecologic Cancers | Ovarian, uterine, cervical, and vulvar cancers | Gynecologic cancer surgery may include removal of the tumor or affected organs, lymph node assessment, or cytoreductive surgery in selected cases. |
| Urologic Cancers | Kidney, bladder, and prostate cancers | Partial or complete removal of the affected organ according to disease stage, with laparoscopic or robotic techniques available in selected cases. |
| Lung and Thoracic Tumors | Lung cancer, mediastinal tumors, and selected chest wall tumors | Removal of part of the lung or other surgical procedures after evaluating disease stage and heart and lung function. |
| Head and Neck Tumors | Tumors of the mouth, larynx, salivary glands, and selected neck tumors | Tumor removal while considering speech, swallowing, and breathing functions. Reconstructive surgery may also be required. |
| Bone and Soft Tissue Tumors | Sarcomas and tumors of the bones, muscles, and soft tissues | Tumor removal while attempting to preserve the limb and its function whenever possible. Reconstruction may be required in some cases. |
Note: Having a tumor that falls within one of these categories does not automatically mean that surgery is appropriate. The decision depends on the type and stage of cancer, the extent of spread, resectability, and the patient’s overall health.
How Does the Doctor Determine Whether a Tumor Is Operable?
The decision does not depend on tumor size alone. Evaluation usually begins by confirming the diagnosis through the biopsy report, followed by determining the stage of the disease and whether it has spread.
CT, MRI, or PET-CT scans may be reviewed depending on the type of cancer, with particular attention to the tumor’s relationship with nearby blood vessels, organs, lymph nodes, and potential sites of metastasis.
The patient’s health and ability to tolerate surgery and anesthesia are also evaluated, including heart, lung, kidney function, nutritional status, and chronic medical conditions.
For patients who have already received chemotherapy or radiation therapy before surgery, new imaging is compared with previous scans to assess the response and determine whether surgery has become more or less appropriate.
Tumor Board Evaluation Before Surgery
In complex cases, the decision to operate should not be made by a surgeon working independently from the rest of the cancer care team.
The discussion usually begins with the biopsy report, imaging results, and cancer stage. The surgical oncologist, medical oncologist, radiation oncologist, radiologist, and pathologist then review the available treatment options and their appropriate sequence.
The outcome may be to proceed directly with surgery, to administer treatment before surgery, or to determine that surgery is not currently the most appropriate option.
This multidisciplinary approach is particularly important for rectal, pancreatic, esophageal, breast, lung, ovarian, and other cancers in which the sequence of treatments may change according to the stage and biological characteristics of the tumor.
Types of Cancer Surgery
Surgery can be used for different purposes and is not limited to complete tumor removal.
- Diagnostic Surgery: Performed to obtain a tissue sample when other methods are insufficient to establish a diagnosis.
- Curative Surgery: Aims to remove the tumor when it is localized and surgically resectable.
- Debulking Surgery: Removes as much of the tumor as possible when complete removal is not appropriate, with the aim of improving disease control or supporting other treatments.
- Palliative Surgery: Performed to relieve pressure, obstruction, pain, or other symptoms caused by a tumor. The NCI lists complete tumor removal, tumor reduction, and symptom relief among the major goals of cancer surgery.
Surgical Margins
In many cancer surgeries, the surgeon does not remove only the visible tumor. An appropriate amount of surrounding tissue may also be removed depending on the type and location of the cancer.
After surgery, a pathologist examines the edges of the surgical specimen to assess what are known as surgical margins.
Finding cancer cells at one of the margins may affect subsequent treatment decisions, such as the need for additional surgery or another treatment. However, interpretation of margin status differs according to the type of tumor and surgical procedure.
Lymph Node Surgery
Lymph nodes are evaluated in certain cancers to help determine the extent of disease spread and establish the stage.
In selected cases, a sentinel lymph node biopsy may be performed. This procedure identifies the first lymph node or group of lymph nodes most likely to receive cancer cells spreading from the primary tumor.
It is commonly used particularly in breast cancer and melanoma and is not a routine procedure for every type of cancer. A negative result may help avoid removing a larger number of lymph nodes and reduce the associated complications.
Organ-Preserving Surgery
One of the goals of modern cancer surgery is to achieve appropriate cancer control while preserving organ function whenever medically possible.
Examples include breast-conserving surgery, partial nephrectomy instead of complete kidney removal in selected cases, and limb-preserving surgery for certain bone and soft tissue tumors.
However, organ preservation should never take priority over oncologic safety. The decision depends on whether the tumor can be adequately removed.
Open Surgery, Laparoscopic Surgery, or Robotic Surgery?
| Technique | Description | When Is It Used? | Advantages | Limitations |
|---|
| Open Surgery | The surgeon uses a larger incision to directly access the tumor and surrounding area. | For large tumors or cases requiring complex removal or broad direct visualization. | Direct control and clear visualization; suitable for complex cases. | Larger incision, more postoperative pain, and a longer recovery compared with minimally invasive techniques. |
| Laparoscopic Surgery | Performed through small incisions using a camera and specialized instruments inside the body. | When the tumor is suitable for minimally invasive surgery and does not require highly complex removal. | Faster recovery, less pain, and smaller scars. | May not be suitable for every tumor or advanced case. |
| Robotic Surgery | A minimally invasive surgical technique in which the surgeon controls robotic instruments from a surgical console. | In selected procedures that require high precision and enhanced instrument movement. | High precision, improved control of fine movements, and recovery similar to laparoscopic surgery. | Higher cost, limited availability, and not suitable for every case. |
There is no single surgical technique that is best for every cancer patient. The choice depends on the type, size, and location of the tumor, as well as the purpose of surgery.
Cytoreductive Surgery and HIPEC
Some cancers may spread to the peritoneum, the membrane lining the abdominal cavity. In selected cases, cytoreductive surgery may be combined with HIPEC.
The procedure begins by removing as much visible tumor as possible from the abdomen, followed by the administration of heated intraperitoneal chemotherapy (HIPEC) during surgery.
The National Cancer Institute defines HIPEC as the administration of a heated solution containing anticancer drugs directly into the abdominal cavity after as much tumor tissue as possible has been removed. It is commonly used in the context of cancers that have spread to the peritoneum.
However, HIPEC is not a standard treatment for every cancer that has spread within the abdomen. The decision depends on the type of tumor, extent of spread, possibility of surgical removal, and the patient’s overall condition. It should be evaluated at a center experienced in this type of procedure.
Treatment Before Cancer Surgery
In some cases, surgery is not the first step in treatment.
Neoadjuvant Therapy may be used before surgery to shrink the tumor, address microscopic disease, or improve the possibility of achieving an appropriate surgical resection.
Treatment may include chemotherapy, radiation therapy, or other systemic treatments depending on the type of cancer.
After treatment is completed, imaging studies are repeated and the medical team evaluates the response before confirming the surgical plan.
Treatment After Surgery
Removing the tumor does not always mean that cancer treatment is complete.
After surgery, the final pathology report, cancer stage, surgical margins, and lymph node findings are reviewed. The medical team then determines whether additional treatment is required.
This may include chemotherapy, radiation therapy, hormonal therapy, targeted therapy, or immunotherapy depending on the type and characteristics of the cancer. NCI information emphasizes that surgery is often combined with other cancer treatments rather than used alone.
What Does the Pathology Report Show After Surgery?
The final pathology report is one of the most important documents a patient receives after cancer surgery.
It describes the type and characteristics of the tumor, its size, the extent of invasion into surrounding tissues, the status of surgical margins, and the lymph nodes that were removed, along with other information depending on the specific cancer.
The final pathology findings may change the stage that was initially estimated before surgery and can help the oncology team determine whether additional treatment or a follow-up program is required.
Patients should therefore keep the complete pathology report, not only the hospital discharge summary.
Preparing for Cancer Surgery
Before surgery, the medical team reviews the biopsy, imaging studies, and previous test results. Additional laboratory tests or new imaging may be requested if the existing results are no longer sufficient for making a surgical decision.
The assessment also includes anesthesia evaluation, current medications—particularly blood thinners—chronic diseases, and nutritional status.
Before major procedures, optimizing nutrition, controlling diabetes, or improving heart and lung function may form part of the preparation process.
Before surgery, the patient should understand the name of the procedure, which organs or tissues will be removed, available alternatives, possible risks, whether intensive care may be required, and what to expect after surgery.
Recovery After Cancer Surgery
There is no standard recovery period for all cancer surgeries.
A patient undergoing a limited procedure may leave the hospital within a short period, whereas complex liver, pancreatic, esophageal, or pelvic surgery may require a longer hospital stay and closer follow-up.
Recovery time is influenced by the extent of surgery, surgical technique, age, overall health, nutritional status, and the presence of complications.
After discharge, follow-up usually focuses on wound healing, nutrition, physical activity, pain management, pathology results, and the next step in the cancer treatment plan.
Risks of Cancer Surgery
Like any operation, cancer surgery may be associated with bleeding, infection, anesthesia-related complications, or injury to nearby tissues. Specific risks vary according to the organ involved and the type of resection.
For example, gastrointestinal surgery carries different risks from breast, kidney, or lung surgery.
The NCI lists pain, infection, bleeding, damage to nearby tissues, and anesthesia-related reactions among the potential risks of surgery.
For this reason, patients should discuss the specific risks of the proposed operation rather than relying only on a general list of surgical complications.
When Is a Second Medical Opinion Important?
Patients may wish to consider a second opinion before surgery when the proposed procedure is major or irreversible, such as complete removal of an organ or multi-organ surgery.
A second opinion may also be useful when the tumor has been considered unresectable, when cancer has returned after previous surgery, or when doctors recommend different sequences of surgery, chemotherapy, or radiation therapy.
Complex procedures such as HIPEC, pancreatic surgery, liver surgery, and major pelvic surgery require careful evaluation of the experience of both the surgical team and the medical center, particularly when several treatment options are available.
How Do You Choose a Surgical Oncologist?
Searching only for the “best surgical oncologist” is not enough. What matters most is whether the surgeon’s experience is directly related to the specific cancer and organ involved.
A surgeon with extensive experience in liver and pancreatic tumors may not necessarily be the most appropriate doctor for lung cancer, and vice versa.
It is also important to determine whether the surgeon works within a multidisciplinary tumor board and whether the center can provide pathology, radiology, intensive care, medical oncology, and radiation oncology services that may be required before or after surgery.
For robotic or laparoscopic surgery, the surgeon’s experience with the specific technique should be evaluated rather than relying only on the availability of the equipment at the hospital.
How Do You Choose a Hospital for Cancer Surgery in Turkey?
The appropriate medical center should be able to manage the entire cancer case, not simply perform the operation.
For complex cancers, priority should be given to centers with a surgeon experienced in the specific cancer, specialized cancer pathology, advanced imaging, medical oncology, radiation oncology, and intensive care when required.
Interventional radiology, nutritional support, rehabilitation, and reconstructive surgery may also be important for certain patients.
For this reason, the most suitable hospital may differ from one type of cancer to another, even within the same healthcare group.
Cost of Cancer Surgery in Turkey
There is no single price that applies to all cancer surgeries.
Costs can differ significantly between a limited surgical biopsy and a complex liver, pancreatic, or pelvic operation. Pricing is also influenced by the type of surgery, duration of the procedure, anesthesia, medical supplies, length of hospital stay, intensive care requirements, pathology testing, and whether reconstruction or additional interventions are needed.
The NCI generally notes that the cost of surgery may be affected by the type of operation, number of specialists involved, type of anesthesia, location where the procedure is performed, and length of hospital stay.
The most accurate estimate can therefore be provided after reviewing the medical file and determining the exact procedure, hospital, and surgeon. Patients should request a quotation that clearly explains what is included and excluded.
Which Medical Reports Are Required for a Cancer Surgery Review Before Travel?
For a useful initial evaluation, it is preferable to provide an organized medical file that includes the complete biopsy report, CT, MRI, or PET-CT images and original DICOM files when available, recent laboratory results, reports of previous surgeries, endoscopy reports when applicable, details of previous chemotherapy or radiation therapy, a list of current medications, and information about chronic diseases.
The medical center may also request pathology slides or tissue blocks to review the diagnosis before making a decision about major surgery.
The more complete and chronologically organized the medical file is, the easier it becomes to identify the appropriate surgeon and determine whether additional tests are required before traveling.
