Oncology surgery: with Dr. Ahmed Mahmoud El-Damaty

Cancer surgery is one of the most important medical specialties in the treatment of many types of cancer. Its primary goal is to completely remove the tumor or reduce its size while preserving as much healthy tissue and organ function as possible. In recent years, oncologic surgery has advanced significantly through the use of minimally invasive laparoscopic techniques, precision surgery, and modern surgical technologies. These innovations have improved treatment outcomes, reduced complications, minimized postoperative pain, and accelerated patient recovery.

Dr. Ahmed Mahmoud El-Dematy emphasizes that early diagnosis and comprehensive evaluation are the foundation for selecting the most appropriate treatment plan and achieving the highest possible success rates in cancer care.

What Is Cancer Surgery?

Cancer surgery is a specialized branch of general surgery that focuses on the treatment of both benign and malignant tumors. The procedure aims to remove the tumor along with an adequate margin of healthy tissue when necessary. In some cases, nearby lymph nodes are also removed to determine whether the disease has spread.

Surgery is often a key component of a comprehensive cancer treatment plan and may be used alone or combined with chemotherapy, radiation therapy, immunotherapy, or targeted therapy, depending on the cancer type and stage.

When Is Cancer Surgery Needed?

A surgeon may recommend cancer surgery in the following situations:

• Removing tumors detected at an early stage

• Obtaining a biopsy to confirm the diagnosis

• Reducing tumor size before additional treatments in selected cases

• Removing tumors that cause symptoms or complications

• Resecting metastatic tumors in carefully selected patients

Dr. Ahmed Mahmoud El-Dematy explains that the timing and type of surgery vary according to the patient's condition, the type of cancer, and its stage.

Types of Tumors That Can Be Treated Surgically

Cancer surgery is commonly performed for a wide variety of tumors, including:

• Breast cancer

• Colon and rectal cancer

• Stomach cancer

• Liver tumors

• Pancreatic tumors

• Thyroid tumors

• Skin and soft tissue tumors

• Various gastrointestinal tumors

The most appropriate surgical approach is determined after careful evaluation of diagnostic findings and tumor staging.

How Are Tumors Diagnosed Before Surgery?

Accurate diagnosis involves several important investigations, including:

• Comprehensive clinical examination

• Computed Tomography (CT) scan

• Magnetic Resonance Imaging (MRI)

• Positron Emission Tomography–Computed Tomography (PET-CT) when indicated

• Tumor marker blood tests in selected cases

• Biopsy and pathological tissue examination for definitive diagnosis

Dr. Ahmed Mahmoud El-Dematy emphasizes that accurate diagnosis is essential for determining the stage of cancer and selecting the most effective surgical strategy.

Modern Techniques in Cancer Surgery

Technological advances have transformed oncologic surgery, leading to safer and more precise procedures.

Laparoscopic Cancer Surgery

Minimally invasive laparoscopic surgery can be used for selected cancers, offering smaller incisions, less postoperative pain, and faster recovery.

Precision Surgery

Advanced surgical techniques allow surgeons to remove tumors while preserving as much healthy tissue as possible.

Image-Guided Surgery

Modern imaging technologies help surgeons accurately identify the location and boundaries of tumors during the operation.

Function-Preserving Surgery

Whenever appropriate, surgeons aim to remove the tumor while maintaining the normal function of the affected organ.

Dr. Ahmed Mahmoud El-Dematy explains that the choice of surgical technique depends on the cancer type, location, stage, and the patient's overall health.

Preparing for Cancer Surgery

To achieve the best possible outcome, patients may undergo:

• Comprehensive laboratory and diagnostic tests

• Cardiac and pulmonary evaluation when necessary

• Adjustment or temporary discontinuation of certain medications under medical supervision

• Preoperative fasting as instructed

• Detailed discussions with the surgical team regarding the procedure and treatment plan

Proper preparation contributes to safer surgery and smoother recovery.

Recovery After Cancer Surgery

Recovery varies according to the type and extent of surgery, but patients are generally advised to:

• Take prescribed medications as directed

• Keep the surgical wound clean and properly cared for

• Resume physical activity gradually according to medical advice

• Follow a healthy and balanced diet

• Complete recommended adjuvant treatments when indicated

• Attend all scheduled follow-up appointments

Following postoperative instructions carefully promotes faster healing and better long-term outcomes.

The Importance of Follow-Up After Surgery

Regular postoperative follow-up is an essential part of cancer care because it helps:

• Detect cancer recurrence at an early stage

• Monitor the patient's response to treatment

• Identify and manage potential complications

• Improve long-term quality of life

Ongoing surveillance plays a crucial role in successful cancer management.

Tips for Reducing the Risk of Certain Types of Cancer

Although not all cancers can be prevented, adopting a healthy lifestyle may reduce the risk by:

• Quitting smoking

• Maintaining a healthy body weight

• Engaging in regular physical activity

• Eating a balanced diet rich in fruits and vegetables

• Participating in routine screening and early detection programs

These preventive measures contribute significantly to overall health and cancer prevention.

Cancer surgery remains a cornerstone of modern cancer treatment, helping to remove tumors, improve survival rates, reduce complications, and enhance patients' quality of life when performed using the appropriate surgical approach. Advances in modern surgical techniques, combined with accurate diagnosis and multidisciplinary care, have significantly improved treatment outcomes.

Dr. Ahmed Mahmoud El-Dematy emphasizes that successful cancer treatment depends on early detection, comprehensive evaluation, precise surgical intervention, and regular follow-up as part of an integrated treatment strategy delivered by a multidisciplinary medical team.
