The tumour is removed with a margin of approximately 4mm and the defect is stitched to leave a scar that is usually at least 3 times as long as the tumour. Cure rates can be up to 95% for certain tumours. It is a good option for most body sites, but for sensitive facial sites, Mohs surgery may be a better option as it allows narrower margins and preservation of healthy skin.
Advantages
- Suitable for any body site
- Good cure rate with low risk of recurrence
Disadvantages
- Scar may be longer than with Mohs surgery
- Lower cure rate than with Mohs surgery
- Stitches are required and the scar will take time to heal and gain full strength
Risks
For a surgical excision the site will generally heal well. The scar will on average be at least three times longer than the length of the lesion. Risks include bleeding, haematoma formation (blood clot under the surface which rarely needs to be drained surgically), dehiscence (the wound may come apart requiring a longer period of healing), infection, pain (which rarely may be persistent), damage to nerves or blood vessels, unsightly scar which may be keloid, raised, dipped or different in texture or colour (lighter, darker or redder compared to the adjacent skin), numbness or burning and the need for further treatment according to the results of pathology.
