Surgery in Cancer Treatment and its Importance

Surgery is a fundamental component of cancer treatment that plays a crucial role in managing and caring for cancer patients. It involves the removal of tumors or cancerous tissues from the body. Surgery can serve various purposes in cancer treatment and is often used with other modalities like chemotherapy, radiation therapy, and targeted therapy.

Surgery in Cancer / why and when Surgery is necessary

Surgery is recommended based on several factors related to the type of cancer, its stage, location, and the patient’s overall health. The decision to undergo surgery for cancer is made after careful evaluation by a multidisciplinary medical team, including oncologists and surgeons. Here’s why and when surgery is necessary for cancer treatment –

Reasons for Surgery

  1. Tumor Removal – The primary reason for surgery in cancer is to physically remove the tumor or cancerous tissue from the body. This can eliminate the source of cancer cells and prevent further spread.
  2. Curative Intent – Surgery is often recommended with the goal of curing the patient of cancer, especially when the disease is localized and hasn’t spread to distant sites.
  3. Local Control – Surgery is effective for cancers that are confined to a specific area. By removing the tumor, surgery can achieve local control and prevent the cancer from invading nearby structures.

4. Diagnosis and Staging – Surgery is used to obtain a tissue sample (biopsy) for accurate diagnosis and to determine the stage of cancer. Staging helps guide treatment decisions.

5. Lymph Node Evaluation – During surgery, nearby lymph nodes are often examined to assess whether the cancer has spread beyond its initial site.

6. Debulking – In cases where complete tumor removal isn’t possible due to size or location, surgery can reduce the tumor size, improving the effectiveness of other treatments.

7. Palliation – Surgery can alleviate symptoms and improve the patient’s quality of life by removing tumor masses that are causing pain, obstruction, or other discomfort.

8. Preventive Surgery – For individuals at high risk of developing certain cancers, preventive surgery might involve removing tissue with precancerous changes to reduce the risk of cancer development.

9. Combination Therapy – Surgery can be combined with other treatments like chemotherapy, radiation therapy, or targeted therapy to maximize treatment effectiveness.

When Surgery is Necessary

  1. Localized Cancer – Surgery is often the treatment of choice for cancers that are localized, meaning they are confined to a specific area and haven’t spread extensively.
  2. Early-Stage Cancers: For cancers detected at an early stage, surgery can provide a high likelihood of cure by removing the tumor before it spreads.
  3. Diagnostic Uncertainty – In cases where a definite diagnosis cannot be obtained through non-invasive methods, surgery may be necessary to obtain a tissue sample for accurate diagnosis.
  4. Curative Potential – When the cancer has a high potential for cure through surgical removal, surgery becomes a primary treatment option.
  5. Tumor Characteristics – The size, type, and location of the tumor influence the decision for surgery. Some tumors are more amenable to surgical removal than others.
  6. Patient’s Overall Health – The patient’s overall health and fitness for surgery are crucial considerations. Surgery might not be recommended if the patient’s health is compromised.

Types of Surgery to Treat Cancer

Surgery is a versatile treatment option for various types of cancer, and different surgical procedures are employed based on the type, location, stage, and characteristics of the cancer. Here are some common types of surgery used to treat cancer –

  1. Curative Surgery – Curative surgery aims to remove the entire tumor along with nearby healthy tissue to achieve complete eradication of cancer cells. This type of surgery is often used for early-stage cancers and has the potential to provide a cure.
  2. Palliative Surgery – Palliative surgery focuses on relieving symptoms, improving quality of life, and enhancing comfort. It aims to reduce pain, obstruction, or other discomfort caused by the tumor, especially in advanced or metastatic cancer cases.
  3. Diagnostic Surgery – Diagnostic surgery involves the removal of a tissue sample (biopsy) to confirm the diagnosis of cancer and determine its specific characteristics. 
  4. Debulking Surgery – Debulking surgery is used to reduce the size of a tumor when complete removal isn’t possible. 
  5. Reconstructive Surgery – After tumor removal, reconstructive surgery may be performed to restore the appearance and function of affected body parts, particularly in cases involving the breast, head, neck, or limbs.
  6. Lymph Node Dissection – This surgery involves the removal of nearby lymph nodes to determine if cancer has spread beyond its original site. 
  7. Mohs Surgery – Mohs surgery is used to treat certain types of skin cancer. It involves removing thin layers of skin and examining them under a microscope to ensure complete removal of cancer cells.
  8. Endoscopic Surgery – This minimally invasive approach uses a thin, flexible tube with a camera (endoscope) to guide the surgical instruments. 
  9. Laparoscopic Surgery – Also known as minimally invasive surgery, this technique uses small incisions and a camera to guide surgical instruments. It is used for certain abdominal and pelvic cancers.
  10. Open Surgery – Traditional open surgery involves making a larger incision to access and remove the tumor. It’s used when tumors are large or difficult to reach using minimally invasive techniques.
  11. Cryosurgery – Cryosurgery uses extreme cold to destroy cancer cells. It’s often used for treating skin cancer or small tumors in various organs.
  12.  Radiofrequency Ablation (RFA) – RFA uses high-frequency electrical currents to heat and destroy cancer cells. It’s commonly used for liver, lung, and kidney cancers.

Advantages of Surgery

Surgery is a valuable and often essential treatment option for cancer patients. It offers several advantages that contribute to the overall management and improvement of a patient’s condition such as –

  1. Localized Treatment – Surgery precisely targets the tumor site, minimizing damage to healthy tissues and organs.
  2. Potential Cure: Curative surgery offers the potential to completely remove the cancer, providing a chance for cure, especially in early stages.
  3. Immediate Results – Surgery physically removes the tumor, providing immediate relief from symptoms like pain, obstruction, or bleeding.
  4. Long-Term Benefit: Successful surgery can lead to long-term remission and reduced risk of cancer recurrence.
  5. Customization – Surgical approaches can be tailored to each patient’s specific needs, cancer type, and stage.
  6. Collaborative Care – Surgery often involves a multidisciplinary team of specialists, resulting in comprehensive and personalized treatment plans.
  7. Quick Symptom Relief – Palliative surgery can rapidly alleviate pain and other discomfort caused by the tumor.
  8. Complementary Treatments – Surgery can be combined with chemotherapy, radiation therapy, and targeted therapy for better treatment outcomes.
  9. Limited Systemic Impact – Unlike systemic treatments, surgery’s effects are localized, reducing potential systemic side effects.
  10. Quality of Life Enhancement – Reconstructive surgery can restore function and appearance, positively impacting a patient’s quality of life.

Patients should engage in thorough discussions with their healthcare team to understand their surgical options, potential benefits, risks, and expected outcomes. In shared decision-making, the patient’s preferences, cancer characteristics, stage, and overall treatment strategy is considered. 

Side Effects of Surgery 

While surgery is a vital treatment option for cancer, it can also be associated with certain side effects and risks. The specific side effects experienced by an individual can vary based on the type of surgery, the extent of the procedure, the patient’s overall health, and other factors. Here are some common side effects of surgery in cancer treatment –

  • Pain and Discomfort
  • Swelling and Bruising
  • Scarring
  • Infection
  • Bleeding
  • Fluid Accumulation
  • Nerve Damage
  • Bodily Function Changes
  • Lymphedema
  • Impaired Mobility
  • Wound Healing Issues
  • Blood Clots
  • Anesthesia Effects
  • Digestive Issues
  • Breathing Problems
  • Emotional Impact

Healthcare providers work closely with patients to manage and minimize side effects, provide appropriate pain management, and ensure a smooth recovery process. Patients are encouraged to communicate openly with their medical team and follow post-operative care instructions to promote healing and reduce the risk of complications.
