Moles analysis

Introduction

Moles, also known as pigmented nevi, are common on the skin. Although most are benign, some can develop into dangerous neoplastic lesions. Being aware of moles and being able to analyse them is key to early detection of skin problems. In this article, we will show you how to recognise a dangerous mole and how to take care of your skin health.

What are moles?

Moles are clusters of melanocytes, or pigment cells, that can appear on the skin in different locations and sizes. They can be congenital, present from birth, or acquired, which appear over time. Congenital moles can be larger and more complex, while acquired ones are often smaller in size and simple in structure. It is important to distinguish between the two, as some types require more attention.

How to recognise a dangerous mole?

Not all moles are dangerous, but it is useful to know the features that may suggest risk. The ABCDE method is used to identify dangerous lesions:

• A (Asymmetry): asymmetry in shape.
• B (Border): uneven, jagged edges.
• C (Color): irregular colouring.
• D (Diameter): diameter greater than 6 mm.
• E (Evolution): changes in appearance over time. Paying attention to these features can help detect potentially dangerous skin lesions.

Diagnosis of moles

Diagnosis of moles begins with a visit to a dermatologist, who assesses the skin lesions. The primary tool is dermatoscopy, which allows a closer look at the structure of the mole. This examination is non-invasive and allows early detection of worrying changes. If necessary, the dermatologist may order further tests, such as a biopsy, to exclude tumours.

When should a mole be removed?

The removal of a mole is recommended when cancer is suspected or when the mole interferes with daily life. The most commonly used methods are surgical excision, laser therapy and cryotherapy. Each of these methods has its own advantages and risks, so the decision to remove should be made after consultation with a doctor.

Prevention and skin protection

Protecting the skin from the sun is key in preventing dangerous skin lesions. The use of UV filter creams, avoiding the sun during peak sunlight hours and wearing protective clothing are basic principles. People with numerous moles should take special care to regularly examine their skin and check their moles.

Changes in the appearance of a mole - what do they mean?

Changes in the appearance of a mole can be normal, but they can also indicate a problem. If a mole is growing rapidly, changing colour or shape, it is worth consulting a dermatologist. Sometimes moles disappear on their own, which is usually not a cause for concern, but if this is accompanied by other changes, it is worth investigating.

Summary

Regular analysis of moles and awareness of their potential changes are key to skin health. With proper prevention and sun protection, the risk of dangerous lesions can be reduced. Early detection and response to lesions is the best strategy in protecting against skin cancer.

FAQ

Is every mole dangerous?

No, most moles are benign, but regular inspection is recommended.

How often should I have my moles examined?

It is recommended that you have your skin examined regularly at least once a year, and more often if you have numerous moles.
