What causes moles?

Have you ever noticed an odd bump on your skin that isn’t quite a pimple? Could it be a mole, and what causes them anyway? Let’s dive into the fascinating world of human skin biology to find out.

The Definition of a Mole

First things first: what exactly is a mole? No, not the burrowing creature that can ruin your perfectly manicured lawn. We’re talking about those little brown spots on our skin. A mole–or nevus, if you want to get fancy–is simply a growth composed of pigment cells called melanocytes.

Where Do Moles Come From?

Now for the real question: how do we end up with these pigmented growths on our bodies in the first place? It turns out there are several factors at play:

Genetics

Sorry folks, but sometimes we just have to blame our parents for everything. Some people are genetically predisposed to developing moles throughout their lifetime. In fact, individuals with light-colored eyes or fair skin are more likely to have moles than those with darker complexions.

Sun Exposure

We all know by now that too much sun can lead to serious health issues like skin cancer. Well guess what? Excessive exposure to ultraviolet (UV) radiation from sunlight is also closely linked to mole formation! This is why it’s so important to use sunscreen regularly and seek shade during peak hours of UV intensity (typically 10am-4pm).

Hormones

There’s another factor beyond our control when it comes to moles: hormones. Pregnant women often notice an increase in the number and size of their moles; this is due in part  to hormonal changes taking place within the body during pregnancy.

Types of Moles

Not all moles look alike – some may be flat while others might protrude from the surface slightly or significantly.  While moles can vary in surface appearance – size, color shape and texture — there are three main types: common, atypical and congenital:

Common Moles

Trust us when we say this…common moles are not basic. They’re the most frequently occurring type of mole, with a typical round or oval shape and an even color distribution throughout their cells. They can grow on any part of the body.

Atypical Moles

Now these moles make things more complicated! Unlike common ones, they typically have irregular shapes or colors to them- that’s why dermatologists consider them as being abnormal. These are commonly seen in individuals with a family history of skin cancer so it’s important to see your doctor if you notice any unusual changes to your skin.

Congenital Moles

Unlike other forms which develop over time (whether because of genetics, sun exposure or hormones), congenital moles – get ready for this one–are actually present at birth. Fun fact: did you know that babies born with very large congenital nevi (more than eight inches) have a higher risk for developing melanoma later on in life?

So Can Moles Be Dangerous?

This is a good question to ask yourself after recognizing some fresh pigmented spots on various parts of your body as well as monitoring those already dealt with before. While most people will only ever encounter benign (non-cancerous) growths during their lifetime –it’s essential something serious like Melanoma–a deadly form of Skin Cancer doesn’t get left under looked.. . This is primarily due to their unique genetic makeup accumulative experience from uv-exposure overtime since we were born—so it pays off big time spotting potentially dangerous indications early!

Melanoma may show some warning signs such as changes in the border around nevus lesions , presence  of multiple shades within mole, uneven borders it and even an increased size! If at any point you notice a mole that has developed new signs or made dramatic changes, don’t wait to see what happens next. Schedule an appointment with your dermatologist ASAP.

Common Characteristics of Normal Moles

To avoid unnecessarily causing panic some common characteristics of normal growths include:

  • Small in size (less than the head of a pencil eraser).
  • Uniform color throughout.
  • Round or oval shape.
  • Flat surface texture.

The ABCDEs of moles

But if any mole presents the following features, take things seriously:

a) Asymmetrical shape – half part does not spell out its resemblance over onto another side,
b) Uneven border – which tends to dip inwards rather than proceed in uniform pattern
c) Multiple colors – Not just different shades of brown for instance but perhaps spread discoloration scheme covering purples reds etc containing speckling veins
d ) Greater diameter which  is usually over six millimeters wide!
e ) Evolving visual representation – during change through months to years experiencing either expansion into depth into skin layers known as thickening up .

If you spot more those unusual characteristics: mark secluding from other nevi using permanent marker until you can get professional advice!!

Even though genetics is not under our control we can always manage sun exposure on day-to-day basis through employing efficient techniques sunscreen available. And don’t forget paying attention to warning signals potentially described by potential bad bunny spots!
