Moles, or nevi, are frequently removed for a variety of reasons. They can be removed by two surgical methods:
- Excision (cutting), with or without stitches
- Excision with cauterization (a tool is used to burn away the mole)
Typically, the doctor or dermatologist (a skin specialist) may choose excision with or without stitches, depending on the depth of the mole and the type of cosmetic outcome desired.
What is a mole?
Many people refer to a mole as any dark spot or irregularity in the skin. Doctors use different terms. But the following types of skin marks such as these are not treated the same way moles are and are not discussed here:
- Birthmarks
- Abnormal formations of blood vessels (hemangiomas)
- Keratoses (benign or precancerous spots, which appear after about age 30 years)
Some people are born with moles. Other moles appear over time.
Sun exposure seems to play a role in the development of moles and may even play a role in the development of atypical, or dysplastic, moles.
The role of heredity cannot be underemphasized. Many families have a type of mole known as dysplastic (atypical), which can be associated with a higher frequency of melanoma or skin cancer.
Risks of Mole Removal
Risks of mole removal methods vary from infection to anesthetic allergy and nerve damage. It is always prudent to choose a dermatologist or surgeon with appropriate skills and experience with these removals. This will decrease your risk associated with this procedure.
Other risks vary depending on the area being treated and the method of removal.
One of the most common difficulties after mole removal is a scar. Many people will attempt to remove moles for cosmetic reasons, not realizing that each and every removal may result in a scar. Many times your surgeon can give you an idea of the type and location of a scar after mole removal before you make your decision about removal.
