Melanoma Excision and Sentinel Lymph Node Biopsy

Melanoma surgery is planned around pathology findings such as Breslow depth, ulceration, location, and stage. Wide local excision removes the melanoma with an appropriate margin; selected patients may also be offered sentinel lymph node biopsy for staging.

Understand the plan

Clear information for your next decision

01

Wide local excision

The prior biopsy site and a measured surrounding margin are removed and sent to pathology.

02

Sentinel node biopsy

A tracer helps locate the first draining lymph node or nodes for surgical sampling.

03

Coordinated care

Dermatology, surgical care, pathology, and oncology may all contribute to the treatment plan.

Common questions

Patient FAQ

What is a sentinel lymph node?

It is the first lymph node or group of nodes expected to receive drainage from the melanoma area.

Does everyone with melanoma need a node biopsy?

No. Recommendations depend on tumor features, stage, risks, and patient preferences.

Why is the excision larger than the original biopsy?

Wide local excision removes additional surrounding skin according to melanoma guidelines.

Comprehensive patient guide

Skin Cancer and Melanoma Removal: anatomy, treatment, and risks

This guide supports an informed conversation with a surgeon. Recommendations must be individualized after examination and review of relevant records.

Related anatomy

Skin contains epidermis, dermis, appendages, nerves, vessels, and underlying fat with lymphatic drainage to regional nodes.

Pathophysiology

UV-related mutations and other factors can produce basal-cell, squamous-cell, or melanoma cancers with different risks of local invasion and spread.

Diagnosis and evaluation

Diagnosis requires biopsy and pathology; melanoma planning uses depth, ulceration, margins, and stage.

Medical and nonsurgical treatment

Nonsurgical care depends on the condition and may include observation, wound hygiene, pressure relief, antibiotics for selected infection, dermatology treatment, negative-pressure therapy, topical care, smoking cessation, nutrition, glucose control, or oncology treatment. Antibiotics do not replace drainage or removal of dead tissue when those are required.

Surgical and procedural treatment

Surgery may include wide local excision, complex closure, graft or flap, and selected sentinel lymph-node biopsy.

Risks and tradeoffs

Risks include bleeding, infection, pain, numbness, scarring, wound separation, delayed healing, contour change, graft or flap loss, recurrence, incomplete excision, positive margins, need for further surgery, and anesthesia complications.

Recovery and shared decisions

Recovery depends on the exact procedure, disease severity, health, work demands, and whether additional treatment is needed. Before treatment, discuss expected pain control, wound care, activity, diet, pathology results, follow-up, and the symptoms that should prompt a call.

  • Ask what alternatives are reasonable.
  • Ask how success and recurrence are measured.
  • Review medications and health optimization.
  • Clarify expected restrictions and follow-up.

Urgent care: Call 911 or seek prompt evaluation for severe or rapidly worsening pain, heavy bleeding, trouble breathing, repeated vomiting, fainting, rapidly spreading redness, or another emergency.
