Skin tags and abnormal moles are common skin growths that can be both unsightly and, in some cases, medically concerning. While skin tags are generally harmless, abnormal moles may sometimes indicate skin cancer, such as melanoma. Fortunately, there are several preventive measures you can take to reduce your risk of developing these skin conditions.
This guide explores the causes of skin tags and abnormal moles, risk factors, and practical prevention strategies based on Australian skincare recommendations.
Understanding Skin Tags and Abnormal Moles
What Are Skin Tags?
Skin tags (acrochordons) are small, soft, flesh-coloured growths that typically appear in areas where skin rubs against skin or clothing, such as the neck, armpits, groin, and eyelids. They are benign and painless but can become irritated if frequently rubbed or snagged.
What Are Abnormal Moles?
Moles (nevi) are clusters of pigmented cells that appear as dark spots on the skin. While most moles are harmless, abnormal moles (dysplastic nevi) may have irregular shapes, uneven colours, or jagged borders, increasing the risk of melanoma.
Causes and Risk Factors
Causes of Skin Tags
- Friction:Â Skin-on-skin or skin-on-clothing friction promotes growth.
- Hormonal changes:Â Pregnancy, diabetes, and hormonal imbalances increase susceptibility.
- Obesity:Â Excess weight leads to more skin folds and friction.
- Genetics:Â A family history of skin tags raises the likelihood of developing them.
Causes of Abnormal Moles
- Sun exposure:Â UV radiation is the leading cause of mole changes.
- Genetics:Â A family history of melanoma increases risk.
- Fair skin:Â People with lighter skin are more prone to sun damage.
- Weakened immune system:Â Immunosuppression may lead to abnormal mole growth.
Prevention Strategies
- Preventing Skin Tags
- a) Reduce Friction
- Wear loose-fitting clothing made from breathable fabrics like cotton.
- Use talcum powder in skin folds to minimise moisture and rubbing.
- b) Maintain a Healthy Weight
- Obesity increases skin folds, leading to more friction. A balanced diet and regular exercise can help.
- c) Manage Hormonal Conditions
- If you have diabetes or polycystic ovary syndrome (PCOS), work with a doctor to regulate insulin and hormone levels.
- d) Proper Skincare
- Keep skin clean and dry, especially in creased areas.
- Avoid excessive scrubbing, which can irritate the skin.
- Preventing Abnormal Moles
- a) Sun Protection
- Wear sunscreen daily:Â Use a broad-spectrum SPF 50+ sunscreen, even on cloudy days.
- Seek shade:Â Avoid direct sun between 10 AM and 4 PM when UV rays are strongest.
- Wear protective clothing:Â Hats, sunglasses, and long sleeves reduce sun exposure.
- b) Regular Skin Checks
- Perform monthly self-exams to monitor moles for changes in size, shape, or colour.
- See a dermatologist annually for a professional skin check, especially if you have a family history of skin cancer.
- c) Avoid Tanning Beds
- Artificial UV exposure significantly increases melanoma risk.
- d) Boost Skin Health
- Eat antioxidant-rich foods (berries, leafy greens) to protect skin cells.
- Stay hydrated to maintain skin elasticity.
When to See a Doctor
While prevention helps, early detection is crucial. Consult a healthcare professional if:
- A mole changes in size, colour, or texture.
- A skin tag bleeds, becomes painful, or grows rapidly.
- New moles appear suddenly, especially after age 30.
Conclusion
Preventing skin tags and abnormal moles involves a combination of lifestyle adjustments, proper skincare, and sun protection. By reducing friction, maintaining a healthy weight, and practising sun safety, you can lower your risk of developing these skin growths. Regular skin checks are essential for early detection of any abnormalities, particularly in Australia, where UV exposure is high.
