It’s followed you since childhood or appeared recently, without warning. Small, dark, sometimes hairy or slightly raised…

The birthmark is as intriguing as it is disturbing. Is it common?

Is this a sign of health or a risk indicator?

In this article, we will lift the veil of secrecy and explain what the presence of a mole really means and, above all, when you should start paying attention to it.

What exactly is a mole?

A mole, also called a nevus, is a small cluster of pigment cells (melanocytes) located in the skin. These cells produce melanin, the pigment responsible for skin color. Therefore, having several moles is completely normal, especially if you have fair skin.

They may be present from birth or appear throughout life, usually by the age of 30 or 35. Some remain subtle, while others become more visible over time, especially when exposed to the sun.

Is a birthmark a serious matter, doctor?

The vast majority of moles are benign. However—because there’s a catch—some can develop into cancers and become suspicious, particularly by developing into melanoma, a type of skin cancer.

That’s why it’s important to know how to observe them. Just as we look for signs of a leak in a pipe or cracks in an old wall, we need to pay attention to the warning signs a mole may be sending out.

Signs to look out for: The ABCDE rule

To identify a potentially dangerous mole, dermatologists use a simple but extremely effective method: the ABCDE rule.

A is for asymmetry: one half doesn’t look like the other.

B is for edges: irregular, poorly defined.

C is for color: several colors in the same mole.

D is for diameter: greater than 6 mm.

E is for Evolution: changing appearance, size, texture, or color.

Just one of these criteria may be enough to warrant seeking specialist advice. This is a golden rule to remember, just as we remember life-saving interventions.

Sun and moles: a relationship to watch out for

The sun is a bit like that friendly but unpredictable friend: sometimes kind, sometimes dangerous. Exposure to UV radiation is one of the main risk factors for developing moles. That’s why it’s so important to use appropriate sun protection and avoid prolonged exposure to sunlight, especially between 12:00 PM and 5:00 PM.

It’s also worth considering tanning booths, which increase the risk of mélanome. In France, the usage est fortement déconseillé, voire interdit aux mineurs.

When should you see a dermatologist?

An annual visit to a dermatologist is recommended, especially if you have many moles, a family history of melanoma, or fair skin. Some dermatologists use dermatoscopy, a tool that allows for a detailed skin examination that works like a precision magnifying glass.

If you notice a sudden change in a mole, don’t delay. Prevention is better than cure!

To sum up

Having moles is completely normal, but it does require a little vigilance. Learn more about them, protect them from the sun, and don’t hesitate to seek advice if you have any concerns. Your skin is speaking to you… you just need to learn to listen.
