Moles

What is a Mole?

A mole, also known as a melanocytic nevus, is a small, dark spot or growth on the skin that is usually brown or black. Moles are collections of pigment cells known as melanocytes. They can appear anywhere on the body and can vary in size, shape, and colour. While most moles are harmless, some can change in appearance or become bothersome, prompting many people to consider removal.

Causes of Moles

Moles develop when melanocytes, the cells responsible for producing pigment in the skin, grow in clusters rather than being spread throughout the skin. The formation of moles can be influenced by several factors:

• Genetics: Many people inherit the tendency to develop moles from their family.
• Sun Exposure: Ultraviolet (UV) radiation from the sun can increase the number of moles and make existing moles darker.
• Hormonal Changes: Periods of hormonal change, such as puberty or pregnancy, can cause moles to appear or change in appearance.

How Common are Moles?

Moles are very common, with nearly everyone having at least a few by adulthood. The number of moles a person has can range from just a few to several hundred, depending on genetic predisposition and environmental factors. It is also normal for new moles to appear or existing ones to change slightly over time, particularly during periods of hormonal fluctuation.

Types of Moles

There are several different types of moles, including:

• Common Moles: Also known as acquired moles, these are small, round, or oval and have a smooth surface.
• Atypical Moles: Also called dysplastic nevi, these are larger than common moles and may have irregular borders and multiple colours. They can sometimes resemble melanoma, a type of skin cancer, but are usually benign.
• Congenital Moles: Present at birth, these moles can vary in size and shape and have a slightly higher risk of becoming cancerous.
• Halo Moles: Characterised by a ring of white skin around them, halo moles occur when the immune system attacks a mole for reasons that are not fully understood.
• Blue Moles: Named for their blue or blue-black colour, these moles are usually benign but can occasionally be associated with skin cancer.

How to Differentiate Between Moles, Lipomas, Cysts, Skin Tags and Warts

It is essential to distinguish between moles and other skin growths to determine the most appropriate treatment. Here’s a quick guide:

• Moles: Pigmented spots that can be flat or raised, usually brown or black.
• Lipomas: Soft, rubbery lumps beneath the skin caused by fat deposits. Typically painless and harmless.
• Cysts: Fluid-filled sacs beneath the skin that can feel firm and may sometimes be painful.
• Skin Tags: Small, soft, skin-coloured growths that are usually found on the neck, armpits, or groin. They are harmless but can be easily irritated.
• Warts: Rough, raised bumps caused by a viral infection (HPV) that are usually skin-coloured or darker.
