Moles are rather common skin growths that form when melanocytes, the cells responsible for skin color, cluster together. These clusters typically appear as little, dark spots on the skin and are usually harmless. While most moles are harmless, it’s very important to monitor any changes in size, shape, or color and see a dermatologist if you have any concerns.
Types of Moles
Congenital Moles: They are moles that appear at birth. They come in a variety of sizes and colors, and while most are harmless, larger congenital moles may have a slightly increased chance of developing skin cancer.
Acquired Moles: These moles appear with time, typically during childhood and adolescence. They are the most common type of mole and may originate from exposure to sunshine.
Dysplastic Nevi: These moles are identifiable by their uneven shape, color, and border. While they are usually larger than other moles, they are not always a sign of cancer. Individuals with a high number of dysplastic nevi may be at a higher risk of developing melanoma.
Causes of Moles
“Moles may be congenital, but usually appear during childhood, and an increase in number is associated with age, fair skin and sunlight exposure,” says PubMed Central.
The major cause of moles is the clustering of melanocytes, or pigment-producing cells in the skin. While this is a natural and common process, several conditions can lead to mole development, including:
Genetics: If your family has a history of moles, you may be more likely to develop them. Genetic factors influence the likelihood of developing moles.
Sun Exposure: Prolonged exposure to the sun’s ultraviolet (UV) rays can stimulate melanocyte growth, resulting in the production of moles. You should prioritize sun protection to reduce the danger of excessive mole development.
Hormonal Changes: Throughout life phases such as puberty, pregnancy, or with the use of hormonal contraceptives, hormonal changes might influence the formation of moles.
Age: Moles are more common in childhood and continue to increase throughout maturity. While the appearance of new moles might continue until later in life, the rate normally decreases with age.
How Do You Understand A Mole Feature?
Knowing the features of moles is of the utmost importance since it makes it possible to identify any skin problems early on. Let’s explore a couple of possibilities for the mole on your skin.
Asymmetry: Determine whether one half of the mole looks different from the other. Imagine drawing a line through the center or you can literally draw a line through its center. Each side of the mole should mirror each other.
Border irregularity: Smooth edged moles are preferable to jagged or fuzzy edged moles. Keep an eye out for any imperfections in the outline of your mole.
Color variation: A healthy mole is usually the same color. If you detect varied tints or colors inside a single mole, it’s important to take note.
Diameter greater than 6 millimeters: Size is important. If the mole’s diameter exceeds 6 mm (about the size of a pencil eraser), it may be a red flag.
Evolving: Moles should behave like old friends, remaining stable and unchanging. If you observe any changes in size, shape, or color, it is an evolution that you need to be concerned about.
When Should You Be Concerned About Your Skin Mole?
If you see any changes in the above mole traits, you should be concerned about your skin mole because these could be symptoms of a skin problem, such as melanoma.
Melanoma is a form of skin cancer that starts in melanocytes, the pigment-producing cells in the skin. It can form in existing moles or as a new, aberrant growth. Melanoma is distinguished by its ability to spread to other areas of the body if not diagnosed and treated promptly.
Furthermore, if a mole gets itchy, uncomfortable, or begins bleeding for no apparent reason, it is cause for concern. It is recommended that you see a dermatologist for further assessment.
Takeaway
Moles are rather common skin growths that form when melanocytes, the cells responsible for skin color, cluster together. There are different types of moles namely: congenital moles, acquired moles, and dysplastic nevi.
According to PubMed, “moles may be congenital, but usually appear during childhood, and an increase in number is associated with age, fair skin and sunlight exposure”. If you see any changes in the mole features, such as asymmetry, border inconsistencies, or color variation in the mole, you should be concerned because they could be indicators of a skin condition, such as melanoma.
