What You Need to Know About Your Moles

Mole or melanocytic nevus is usually described as a skin imperfection. A
mole is called a nevus, while moles are called nevi. Moles are caused by
groups of skin cells called melanocytes. The color of moles is usually tan,
brown, black, red, pink, or skin-colored. The form could be smooth, flat,
wrinkled, or raised. Most of them are oval or round and have a size of not
more than 6 millimeters.


Moles can appear anywhere in the skin and most moles appear during
childhood. It is normal to have around 10-40 moles on your skin. Apart
from the genetic reason, the number of moles can be increased by how
much sun exposure you get in the past or during your earlier childhood.
Usually, moles can get darker due to sun exposure and pregnancy.

There are three types of moles; congenital nevi, dysplastic nevi, and
acquired nevi.
• Congenital nevi are a type of mole people get when they’re born. It
is commonly called a birthmark. Study estimates between 0-5%
chance of congenital nevi developed into melanoma. It depends on
the size of the nevus. Very large congenital nevi have a higher risk
and small nevi have a lower risk.
• Dysplastic nevi or atypical moles usually have irregular edges or
surfaces, larger than usual moles, and have various colors. People
with five or more dysplastic nevi have a higher chance to develop
melanoma.
• Acquired nevi usually appear during childhood and adulthood. Most
of them are benign or having less risk to develop skin cancer.

Sometimes, moles can change over time. Some of them can get darker or
grow hair there. If you are one of the high-risk people, then you should do
ABCDE screening regularly. When the moles have major changes, you
must be careful of developed skin cancer.


Some people are not bothered by the appearance of their moles but some
may think of it as bothersome. Some of them keep it as the beauty mark
although many people remove their moles. Moles can be removed by
minor surgery. It is highly advised to go check-up with your dermatologist
before removing your moles.
