What to Expect During Mohs Surgery for Skin Cancer
Mohs surgery is considered the gold standard for removing skin cancers, especially on the face or areas where preserving tissue is crucial. Unlike traditional excisions, Mohs surgery removes cancerous tissue layer by layer, allowing dermatologists to check each layer under a microscope immediately. This approach maximizes removal of cancer cells while sparing healthy tissue.
Why Mohs Surgery Is Recommended
Mohs surgery is ideal for:
Basal cell carcinoma
Squamous cell carcinoma
Recurrent skin cancers
Cancers in cosmetically sensitive areas
It offers higher cure rates, precise tissue preservation, and lower recurrence risk compared to standard excision.
The Procedure: Step by Step
Local Anesthesia
The area is numbed so the patient feels minimal discomfort. General anesthesia is usually unnecessary.Layered Removal
The dermatologist removes the visible tumor along with a thin layer of surrounding tissue.Microscopic Examination
The tissue is examined in real-time to check for cancer cells. If cancer remains, another layer is removed.Repeat Until Clear
The process continues until no cancer cells are detected.Wound Reconstruction
Depending on the size and location, the surgeon may close the wound with stitches, let it heal naturally, or perform a skin flap or graft.
Recovery and Care
Mild swelling and redness are common
Keep the wound clean and covered as instructed
Avoid sun exposure on the treated area until fully healed
Stitches are typically removed in 5–14 days, depending on the location
Most patients can return to normal activities immediately, making it a convenient option for busy schedules.
Benefits of Mohs Surgery
Highest cure rate for skin cancers
Minimal removal of healthy tissue
Optimized cosmetic outcomes
Immediate microscopic evaluation prevents recurrence
Who Should Consider Mohs Surgery
Patients with skin cancers:
On the face, neck, ears, or hands
That are recurrent or aggressive
With high-risk features (size, location, histology)
Mohs surgery is a precise, effective, and safe procedure that prioritizes cure and cosmetic outcome. If you have a suspicious lesion or recurrent skin cancer, early consultation with a board-certified dermatologist is critical for best results and peace of mind.
