Wide excision of melanoma in Turkey: what it is and why margins matter

Wide excision of melanoma (often called wide local excision) is the definitive surgical procedure performed after a skin biopsy confirms cutaneous melanoma. While the initial biopsy removes the suspicious mole to establish tumour type and Breslow thickness, wide excision removes the biopsy scar alongside a measured perimeter of healthy skin and underlying subcutaneous fat down to the deep fascia.

This clearance removes any microscopic cancer cells lingering near the original site, reducing local recurrence risk. In Turkey, surgical oncology units perform wide local excision following international clinical guidelines, coordinating with pathology and reconstructive teams to ensure clear histological margins.

How does a wide local excision remove melanoma cells?

Cutaneous melanoma begins in epidermal melanocytes and invades downward into the dermis. Even when an initial biopsy appears clear, microscopic melanoma cells or micrometastases can reside in adjacent lymphatic channels. Without an adequate clearance margin, these cells risk causing local recurrence or lymphatic spread.

Similar to margin-clearing cancer operations such as a lumpectomy for breast tissue, wide excision establishes a protective boundary of normal tissue. Standard radial margins depend on the tumour Breslow thickness:

  • Melanoma in situ: 5 mm radial margin.
  • Breslow thickness under 1.0 mm: 1 cm radial margin.
  • Breslow thickness 1.01 mm to 2.0 mm: 1 cm to 2 cm margin.
  • Breslow thickness over 2.0 mm: 2 cm radial margin.

The surgeon marks an ellipse around the scar and excises vertically to the deep fascia, ensuring uniform margin depth. The specimen is oriented with sutures for microscopic margin verification.

Does wide excision of melanoma work: what clinical trials show

Yes. International multicentre randomised trials demonstrate that wide local excision achieves dependable local disease control. Landmark studies organised by the World Health Organization Melanoma Programme and the Intergroup Melanoma Trial confirmed that adherence to recommended margins yields local recurrence rates below five percent for thin tumours.

Trials comparing 1 cm to 2 cm margins against historical 3 cm to 5 cm margins showed equivalent overall survival and local control. Wider excisions did not improve survival but caused higher rates of wound breakdown, nerve numbness, and complex grafting. Current guidelines therefore emphasise tissue-sparing margins that balance oncological safety with low morbidity.

Wide excision treats local disease at the primary site. It cannot reverse spread that occurred before surgery, which is why staging and ongoing dermatological surveillance remain essential. Responsible oncology teams do not guarantee complete protection from systemic recurrence.

Wide excision of melanoma cost in Turkey compared with the UK, US and Germany

The approximate price ranges below reflect private hospital costs for wide local excision. Final fees depend on anatomical location, defect size, anaesthetic type, and whether primary closure, a skin flap, or grafting is needed. Each hospital provides an itemised quote after reviewing pathology reports.

CountryApproximate cost range
Turkey€1,500 – €4,800
United Kingdom€3,500 – €8,500
United States€4,500 – €14,000
Germany€3,000 – €7,500

Cost variations reflect surgical complexity. A trunk excision closed linearly under local anaesthesia sits at the lower end. Excisions on the face or lower leg requiring general anaesthesia, flap reconstruction, or concurrent sentinel lymph node biopsy cost more due to surgical time and theatre resources.

In Turkey, treatment packages typically cover surgical fees, theatre costs, pathology margin analysis, pre-operative bloods, aftercare dressings, and airport transfers. You can request a written quote through our free quote page.

Wide excision versus Mohs surgery and staged excision

Standard wide local excision is the international reference treatment for primary melanoma, but alternative surgical techniques are applied in specific clinical scenarios.

Surgical approachBest suited toTypical limits
Standard wide local excisionTrunk, arms, legs and areas with loose skinMay require grafting in tight or delicate areas
Mohs micrographic surgeryFace, scalp, hands or lentigo malignaTechnically demanding; requires specialised margin assessment
Wide excision with flap or graftLarge defects or lower leg wounds under tensionAdditional donor site wound and longer healing period

Standard wide excision relies on permanent paraffin sections, providing the most reliable assessment of melanocytic cells. Mohs surgery evaluates frozen sections intra-operatively; because single atypical melanocytes are difficult to interpret on standard frozen slides, specialised centres use modified staged excision ("slow Mohs") with rapid paraffin sections to achieve clear margins on the face while conserving healthy tissue.

Who needs wide excision of melanoma, and when is sentinel node biopsy added?

Wide local excision is required for all patients with biopsy-proven primary cutaneous melanoma, from melanoma in situ to invasive disease. Candidates must be medically suitable for minor or moderate soft-tissue surgery under local or general anaesthesia.

Immediate wide excision alone is not appropriate for patients with clinically detectable regional lymph node metastases or distant disease, where systemic therapy or lymphadenectomy takes precedence. As with other oncological operations such as the removal of colon cancer, accurate staging dictates the surgical sequence.

For tumours with Breslow thickness exceeding 1.0 mm (or over 0.8 mm with ulceration), guidelines recommend sentinel lymph node biopsy (SLNB). Performed during the same operation, SLNB identifies and samples the primary draining node to detect microscopic nodal spread and determine whether adjuvant therapy is warranted.

What happens during the wide excision procedure step by step?

The operation follows a clear, structured sequence designed to maximise oncological clearance and promote clean wound healing:

  • Surgical marking: The surgeon marks the previous biopsy scar and measures the radial margin with a surgical ruler, designing an elliptical excision aligned with natural skin tension lines.
  • Anaesthesia: Local anaesthetic with adrenaline is injected for simple excisions. General anaesthesia is used when sentinel node biopsy or complex tissue transfer is planned.
  • Tissue excision: The surgeon cuts vertically through skin and subcutaneous fat to the deep fascia, removing the tissue block intact without disturbing tumour borders.
  • Haemostasis: Electrocautery seals small vessels to prevent haematoma formation.
  • Wound closure: Subcutaneous tissues are closed with dissolvable sutures to relieve tension, followed by skin sutures, staples, or a local flap or skin graft if the defect is wide.
  • Histopathology: The specimen is oriented with suture markers and sent for comprehensive microscopic margin analysis.

Simple excisions take 30 to 45 minutes; cases involving sentinel node biopsy or flap reconstruction take up to two hours.

What to expect from wide excision results, scarring and before and after

Because safety margins require removing healthy skin around the scar, the surgical ellipse produces a linear incision approximately three to four times the width of the excision defect. Patients reviewing before-and-after photographs should expect a distinct surgical scar rather than an unblemished cosmetic outcome.

Initially, scars appear red, raised, and firm. Over six to twelve months, normal collagen remodelling softens and fades the mark into a pale, flat line. If a skin graft or local flap was required, subtle colour and texture differences may persist along the boundary.

Photographs cannot depict the most important outcome: negative histological margins. A clear margin confirmed by a pathologist is the primary measure of procedural success, with cosmetic refinement taking secondary priority.

Your trip to Turkey, aftercare and recovery timeline

For wide local excision under local anaesthesia, plan to stay in Turkey for four to five nights. If your treatment includes general anaesthesia, sentinel lymph node biopsy, or skin grafting, a stay of six to eight nights allows adequate wound monitoring before you fly.

Recovery milestones follow a predictable timeline:

  • Days 1 to 3: Keep dressings clean and dry. Rest with the treated limb elevated to limit swelling. Manage mild tenderness with paracetamol.
  • Days 5 to 7: Follow-up inspection at the hospital. Facial sutures are typically removed at this stage.
  • Days 10 to 14: Sutures or staples on the trunk or limbs are removed. Skin grafts are checked for healthy adherence.
  • Weeks 2 to 4: Resume desk work and light routines. Avoid vigorous exercise, heavy lifting, and swimming until wounds fully seal.
  • Months 3 to 12: Protect the scar from sunlight using SPF 50+ sunscreen. Gentle silicone gel massage helps soften matured scar tissue.

Potential surgical risks and oncological follow-up

Wide local excision is a routine procedure, but all operations carry potential complications. Respected organisations such as the National Health Service (NHS) and the British Association of Dermatologists identify the following risks:

  • Infection: Characterized by redness, heat, or discharge; treated with oral antibiotics.
  • Haematoma or seroma: Fluid or blood collecting under the incision, occasionally needing needle aspiration.
  • Wound breakdown: Edge separation from physical tension, managed with specialised dressings.
  • Nerve altered sensation: Local numbness from severed cutaneous nerve twigs, which usually lessens over several months.
  • Graft failure: Partial breakdown of grafted skin from poor vascular uptake.
  • Incomplete clearance: In rare cases, pathology reveals positive margins, requiring further surgical re-excision.

Surgery manages the primary tumour, but ongoing dermatological surveillance remains vital. Full-body skin checks every three to six months ensure prompt identification of any new or recurrent lesions.

How to choose an oncology surgeon in Turkey and key questions to ask

Ensure your surgeon is a board-certified surgical oncologist or plastic surgeon registered with the Turkish Medical Association, operating in a licensed hospital with accredited pathology facilities and intensive care support.

Be cautious of clinics promoting "scarless" skin cancer removal, surgeons quoting fees without examining pathology reports, or facilities lacking oncological credentials. Learn more about how our process works and submit your details for evaluation through our free quote portal.

Questions to ask your surgical team:

  • What radial margin in millimetres do you plan based on my Breslow depth?
  • Will the operation use local, regional, or general anaesthesia?
  • Does my tumour profile indicate sentinel lymph node biopsy?
  • How will the surgical defect be closed—primary closure, flap, or graft?
  • When will definitive histological margin results be ready?
  • What is the protocol if surgical margins are not clear?
  • What summary documentation will be provided for my doctor at home?

Frequently asked questions

Wide excision of melanoma, or wide local excision, is a surgical procedure that removes the scar from a diagnostic biopsy alongside a measured margin of healthy surrounding skin and underlying fat. The objective is to eliminate any microscopic melanoma cells that may remain in the immediate tissue, lowering the risk of local cancer recurrence.

Yes. Large-scale international clinical trials demonstrate that wide local excision achieves high rates of local disease control. Clinical guidelines recommend margins of 1 cm to 2 cm depending on the tumour Breslow thickness. These standardised margins prevent local recurrence as effectively as historically wider excisions while preserving healthy tissue and improving surgical recovery.

In Turkey, the cost of wide local excision typically ranges from approximately €1,500 to €4,800, compared to €3,500 to €8,500 in the UK. The price varies depending on the defect size, anatomical location, whether general anaesthesia or skin grafting is required, and whether a concurrent sentinel lymph node biopsy is performed.

Because the surgeon must remove a radial margin around the original biopsy site in an elliptical shape, the final scar is usually three to four times longer than the defect width. Over six to twelve months, the incision fades from a firm, red mark into a flat, pale linear scar.

Initial wound healing takes about one to two weeks, when sutures or staples are removed. Most patients resume non-strenuous desk work within seven to ten days. Strenuous sports, heavy lifting, and swimming should be avoided for three to four weeks. Full scar maturation and tissue softening continue over six to twelve months.

During the procedure, you will feel no pain because the area is thoroughly numbed with local anaesthetic or you are asleep under general anaesthesia. Afterwards, moderate soreness, tightness, and bruising are normal for several days. This discomfort is usually well controlled with standard oral painkillers such as paracetamol or mild codeine.

When clear histological margins are achieved according to clinical guidelines, wide local excision provides excellent local disease control, with local recurrence rates typically under five percent for thin melanomas. However, it cannot prevent distant recurrence if microscopic cancer cells had already entered the lymphatic or vascular system prior to surgery.

Wide local excision is a safe and standardised surgical procedure performed routinely worldwide. Potential complications include post-operative bleeding, wound infection, fluid accumulation, delayed wound healing, and prominent scarring. Serious complications are rare, particularly when the operation is performed in an accredited hospital under strict sterile surgical standards.

Standard wide local excision is the international benchmark for trunk and limb melanomas, using formal paraffin pathology to check margins. Mohs surgery, often adapted as staged excision with rapid paraffin sections, is primarily reserved for complex facial or head melanomas where tissue preservation is critical to retain function and aesthetics.

For a simple wide excision under local anaesthesia, plan to stay in Turkey for four to five nights so the surgical team can monitor early wound healing. If you require general anaesthesia, a skin graft, or concurrent sentinel lymph node biopsy, a stay of six to eight nights is recommended.
