TREATMENTS
Shave biopsy & shave excision
A shave biopsy removes a superficial skin sample for diagnosis; shave excision may also remove a known benign raised lesion.
- Used for diagnosis of uncertain or suspicious lesions
- May be used for selected raised lesions where cosmetic outcome is not the priority
- Does not provide full-thickness removal
Diagnostic biopsy
If there is sufficient time, your doctor may be able to perform a shave biopsy on the same day as your consultation or skin check. This cannot be guaranteed on every occasion; a separate appointment may be needed.
A shave biopsy provides a sample for examination by a pathologist. The result helps your doctor decide whether further treatment is needed. It does not necessarily remove the whole lesion or establish that its deeper margins are clear.
Removal of a benign raised lesion
Shave excision may be considered for a lesion assessed as benign. The doctor will discuss scarring, possible regrowth and whether another method is more appropriate. Learn about cosmetic mole removal options.
Radiofrequency and laser are not substitutes for a diagnostic biopsy when tissue examination is needed.

How it’s done
- The doctor injects local anaesthetic into the skin to make it numb.
- They then use a razor-like blade to shave off a thin layer of skin from the top. This sliver of skin is removed, leaving a small patch of “raw” skin behind.
- The doctor applies pressure (or may use cautery or topical aluminium chloride) to the area to minimise bleeding, and then places a dressing over the wound.
How to prepare
Get best results and minimise scarring by being well-prepared.
Shave around the area to be biopsied to a distance of about 5cm. This makes it easier for the surgeon to see the lesion to be biopsied, but also allows an adhesive dressing to stick to the skin.
Don’t apply make-up or skin care products to the area.
After the procedure
For 2-3 days, don’t put the area under water and avoid sweating if possible. Don’t wash with soap or apply any active products.
The wound will heal gradually from the bottom. This may take several weeks.

Side effects and what to expect
Shave procedures can heal well, but outcomes vary depending on the location and depth of the lesion.
- Scarring is common and may be more noticeable in some areas of the body
- Healing can take several weeks, particularly on the lower leg
- There may be pigment changes (lighter or darker areas of skin)
- Regrowth can occur if deeper components of the lesion remain
For a known benign lesion, other removal options may be discussed. If the diagnosis is uncertain, obtaining suitable tissue for pathology takes priority.
Why a shave procedure may be considered
Fees
Assessment and treatment are charged separately. See our assessment fees and biopsy and surgery fees. Your doctor will explain the proposed costs before treatment.
Pathology charges may apply separately.
Skin lesion assessment and biopsy
A doctor examines the lesion before recommending a biopsy or removal. A procedure may be possible during the consultation, or a separate appointment may be needed.
