When it comes to changes or growths on the skin, it’s common for people to confuse skin tags with moles. Although both are generally harmless, they are distinct in their appearance, causes, and medical implications. Understanding these differences is important for recognising any potential concerns and knowing when to seek medical advice.

In this article, we’ll explore what skin tags and moles are, how to tell them apart, what causes them, and what to do if you notice changes. Whether you’ve spotted a new bump or are just curious, this guide will help you distinguish between the two.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are small, soft, benign growths that usually hang off the skin. They are typically flesh-coloured or slightly darker and have a smooth or slightly wrinkled surface. Skin tags are connected to the skin by a thin stalk called a peduncle.

They most commonly appear in areas where skin rubs against skin or clothing, such as:

Skin tags are not contagious and tend to be more common in adults, especially those who are overweight, have diabetes, or are pregnant (due to hormonal changes).

What Are Moles?

Moles, or melanocytic naevi, are pigmented skin lesions that occur when melanocytes (the pigment-producing cells in the skin) grow in clusters. Unlike skin tags, moles can be flat or raised, and they vary widely in colour — from pink to dark brown or black.

Moles can appear anywhere on the body and may be present at birth (congenital moles) or develop over time. Most people have between 10 to 40 moles by adulthood.

Some moles remain unchanged for years, while others may gradually change in size, colour or shape. While most are harmless, certain types of moles can develop into melanoma, a serious form of skin cancer.

Why Do They Appear?

Skin Tags:
Skin tags often result from friction or irritation. This is why they are common in areas where skin rubs together or against clothing. Hormonal changes during pregnancy and high levels of insulin in people with type 2 diabetes can also contribute to their development.

Some people may be genetically predisposed to skin tags, and they are more prevalent in middle-aged and older adults.

Moles:
Moles develop when melanocytes grow in clusters. They may form due to genetic factors, sun exposure, and hormonal changes, particularly during puberty or pregnancy.

Sunburns and frequent sun exposure can increase the number of moles and the risk of some becoming cancerous. Fair-skinned individuals or those with a family history of melanoma should monitor their moles more carefully.

Should You Be Concerned?

While both skin tags and moles are usually harmless, any new growth or change in the skin should be evaluated, especially in moles. Moles that change in shape, colour, size, or become itchy, painful, or start bleeding may require further examination.

Use the ABCDE rule to assess moles:

Skin tags do not turn into cancer. However, they may become irritated from friction or accidentally torn, which can cause discomfort or minor bleeding. If this happens regularly, removal might be considered.

Diagnosis and Treatment

Diagnosis:
Most skin tags and moles can be diagnosed through visual inspection by a GP or dermatologist. In some cases, a dermatoscope may be used for a closer look. If there is any suspicion of malignancy in a mole, a biopsy may be recommended.

Treatment:

Skin Tag Removal Options:

These procedures are generally safe and performed quickly in a clinic. They are usually considered cosmetic and not covered by Medicare.

Mole Removal Options:

If there’s any chance the mole is cancerous, excision is preferred and the tissue is sent for biopsy. Medicare may cover mole removal if there’s a medical reason.

Prevention Tips

While not all skin tags or moles can be prevented, you can take some steps to reduce your risk.

Final Thoughts

Understanding the differences between skin tags and moles is essential for maintaining good skin health.
