How is a mole removed?
Moles can be removed using the following methods:
- Shaving/coagulation
- Excision
The dermatologist determines which method is most suitable in each case.
Shaving/coagulation
Shaving is used for raised moles and is done under local anaesthesia. During the treatment the top layer of the skin is shaved off using a very sharp knife. After this, the wound is closed with the aid of heat (coagulation). A scab will form over the damaged tissue once the skin begins to heal, and more healthy cells are produced to restore the damaged tissue. When the skin underneath the scab has healed, the scab falls off.
Exision
Excision is used for flat moles and is also done under local anaesthesia. The entire mole and part of the surrounding skin are removed, after which the wound is sutured. The wound will heal within a few weeks. Depending on the location of the mole on the body, the dermatologist will either opt for subcutaneous (soluble) sutures or for sutures which must be removed after about a week
Risks and complications
Prior to treatment your dermatologist will discuss the risks with you. The risks include:
- Discoloration of the skin: the skin may become slightly lighter or darker, you will therefore be advised to avoid exposure to the sun for at least 6 weeks
- Development of scar tissue
- Scar inflammation
- Bruising
Moreover, when the shaving / coagulation method is use, there is a risk that the mole will grow back.
