Mohs Surgery
What Is Mohs Surgery
Mohs Micrographic Surgery is a specialised surgical technique used to remove skin cancer with exceptional precision.
Unlike traditional excision, Mohs surgery removes the cancer in stages. Each layer is examined microscopically during the procedure until no cancer cells remain.
This approach offers:
- Maximum preservation of healthy tissue
- Extremely high cure rates
- Immediate margin assessment
- Reduced risk of recurrence
- Better cosmetic outcomes
Ocean Clinic describes Mohs surgery as one of the most precise treatments available for skin cancer management.
Which Skin Cancers Can Be Treated?
Mohs surgery is commonly used for:
Basal Cell Carcinoma (BCC)
The most common skin cancer.
Mohs surgery is particularly valuable for:
- Recurrent BCC
- Large lesions
- Facial lesions
- Poorly defined tumours
Squamous Cell Carcinoma (SCC)
Often recommended when:
- The lesion is located on the face
- Tissue preservation is important
- The cancer has higher-risk features
Selected Rare Skin Cancers
Certain uncommon skin cancers may also benefit from Mohs surgery depending on specialist assessment.
Treatment recommendations depend on:
- Cancer type
- Location
- Size
- Previous treatments
- Individual risk factors
Why Is Mohs Surgery Different?
Traditional Excision
With standard excision:
- The lesion is removed
- Tissue is sent to a laboratory
- Results may take several days
Mohs Surgery
With Mohs surgery:
- Cancer is removed layer by layer
- Each layer is examined immediately
- Additional tissue is removed only where cancer remains
- Healthy tissue is preserved
This makes Mohs particularly valuable in cosmetically sensitive areas such as the face.
Areas Commonly Treated
Mohs surgery is frequently performed on:
- Nose
- Eyelids
- Lips
- Ears
- Cheeks
- Forehead
- Scalp
- Neck
These areas require careful tissue preservation to maintain both appearance and function.
What Happens During Mohs Surgery?
1. Local Anaesthetic
The treatment area is numbed using local anaesthetic.
Patients remain awake throughout the procedure.
2. First Tissue Removal
The visible cancer is removed along with a very thin surrounding layer.
3. Immediate Microscopic Analysis
The tissue is examined while the patient waits.
If cancer cells remain, their exact location is identified.
4. Additional Targeted Removal
Only the affected area is removed.
This process is repeated until all cancer cells have been eliminated.
Ocean Clinic notes that procedure length varies depending on how many stages are required.
Who Is a Good Candidate?
Mohs surgery may be recommended for patients who:
- ✓ Have facial skin cancer
- ✓ Have recurrent skin cancer
- ✓ Have large or aggressive lesions
- ✓ Need maximum tissue preservation
- ✓ Have skin cancer near the eyes, nose, lips or ears
- ✓ Want the highest possible cure rates
A dermatology consultation determines whether Mohs surgery is the most appropriate treatment option.
Benefits of Mohs Surgery
- ☆ Very high cure rates
- ☆ Maximum healthy tissue preservation
- ☆ Lower recurrence risk
- ☆ Immediate microscopic confirmation
- ☆ Excellent cosmetic outcomes
- ☆ Ideal for facial skin cancers
- ☆ Single-day diagnosis and treatment process
These advantages make Mohs surgery one of the most effective skin cancer treatments available.
Recovery & Aftercare
Recovery depends on:
- Treatment area
- Reconstruction required
- Size of the defect
Typical Recovery Timeline
- Day 1–3: Mild swelling and bruising
- Week 1: Initial wound healing
- Week 1–2: Suture removal (if required)
- Several weeks: Scar maturation begins
- Several months: Continued scar improvement
Patients receive detailed aftercare instructions and follow-up reviews.
Risks & Considerations
As with any surgical procedure, risks may include:
- ✓ Bruising
- ✓ Swelling
- ✓ Bleeding
- ✓ Infection
- ✓ Temporary discomfort
- ✓ Scarring
- ✓ Need for reconstruction
These risks are generally low when surgery is performed by experienced specialists.
