Moles, also called nevi (singular: nevus), are skin growths due to a collection of pigment-producing cells known as melanocytes. The term "nevus" is derived from the Latin word for birthmark, indicating a possible genetic cause for their occurrence, especially in younger individuals. Unlike skin tags, which consist of epithelial cells and collagen, melanocytes form moles. They are typically embedded within the skin layers and do not have roots or stems like warts. To understand why moles form, refer to the causes and symptoms section.
Types of Moles and Their Risk Levels
At Smart Surgeons, we frequently encounter various types of moles. They are typically categorized based on their appearance and the depth of the melanocytes within the skin layers, which is crucial for determining the appropriate removal method.
- Dermal Nevus: This is the most common type of mole we treat. These moles can grow hair, are raised, and often appear on the face. Due to these characteristics, many people find them unattractive.
- Congenital Nevus: Many patients report having moles since childhood. These congenital nevi moles are often removed for personal reasons, such as an upcoming wedding or career advancement.
- Freckles: Although not technically moles, freckles resemble them. Since freckles are more numerous and spread out, they require different treatment methods than typical moles.
Moles are also classified based on their depth within the skin:
- Dermal Nevus: This type is located in the dermis, making it more superficial and prone to becoming raised and flesh-colored.
- Junctional Nevus: Found at the junction of the dermis and epidermis, these moles are more superficial and can appear darker.
- Compound Nevus: These moles span both the dermis and epidermis.
Our doctor will select the most suitable treatment based on the type and depth of the mole. For instance, larger and deeper moles may require surgical excision for better results, while smaller moles can be removed with laser treatment for quicker healing.
Important Note:
If you have a mole with any of the following symptoms, known as a Dysplastic Nevus, you should see a dermatologist immediately:
- Irregular Borders: These moles often have poorly defined edges.
- Size: Larger moles have a higher risk of cancer development.
- Color: Dysplastic moles may exhibit multiple colors or change over time.
- Skin Changes: The skin over the mole may become dry, itchy, or hardened.
If you notice these signs, consult a doctor to assess the mole.
Why Do Some People Choose to Keep Their Moles?
Moles also have cultural significance, influencing whether individuals remove or retain them. In India, moles are often referred to as beauty spots, with their location on the body sometimes linked to traditional beliefs or fashion trends. For example:
- A mole on the forehead is said to symbolize wisdom and prosperity.
- A mole on the cheek signifies a caring and responsible personality.
- A mole on the chin is thought to represent determination and stubbornness.
In some cultures, moles on areas like the cheek, neck, or above the lips are considered attractive. Older Indian films often portrayed villains with prominent facial moles, though this trend has faded. It’s important to note that these associations are based on cultural beliefs and have no scientific backing.
Ultimately, the decision to keep or remove a mole is personal. The only medical reason to remove a mole is if there is a risk of it becoming cancerous.
