Skin lesions are areas of the skin that look different from the surrounding skin. They can range from harmless moles to more serious growths that may require medical attention. Knowing the difference between benign (non-cancerous) and malignant (cancerous) lesions is important for early detection and effective treatment.

Benign lesions usually grow slowly, stay clearly defined, and do not spread to other areas. Examples include seborrhoeic keratoses, dermatofibromas, and common moles. These are generally not dangerous unless they become irritated or affect appearance.

Malignant lesions are cancerous and can grow quickly, invade surrounding tissue, and spread to other parts of the body. Common types include basal cell carcinoma, squamous cell carcinoma, and melanoma. Early detection is crucial for better outcomes.

How to Spot Concerning Lesions

The ABCDE rule is a helpful guide to spot potential warning signs, especially for melanoma:

• A – Asymmetry: One half of the lesion does not match the other half.
• B – Border: Irregular, notched, or blurred edges may indicate risk.
• C – Colour: Uneven or multiple colours in one lesion are concerning.
• D – Diameter: Lesions larger than 6mm should be checked, though smaller ones can also be risky.
• E – Evolution: Any changes in size, shape, colour, or symptoms like itching, tenderness, or bleeding need prompt attention.

Even if a lesion does not fit all these criteria, any change should be assessed by a healthcare professional.

Common Benign Lesions That Can Look Like Cancer

Some harmless growths can resemble cancer, which is why professional assessment is important:

• Seborrhoeic keratoses: Waxy, stuck-on patches that can look irregular.
• Dermatofibromas: Firm, round nodules that dimple when pinched.
• Pyogenic granulomas: Red, rapidly growing lesions that bleed easily.
• Atypical moles (dysplastic naevi): Moles that may look unusual but are not cancerous.
• Solar lentigines (age spots): Pigmented spots from sun exposure.
• Cherry angiomas: Small red bumps that are harmless but can sometimes look suspicious if injured.

When to See a Professional

Seek prompt evaluation if a lesion shows:

• Rapid growth over weeks or months
• Bleeding without injury
• Ulceration or crusting
• Tingling, pain, or numbness
• New lesions around an existing growth
• Changes in a mole after age 40

Early consultation allows for accurate diagnosis and treatment, reducing the risk of complications.

Treatment Options

Treatment depends on the type of lesion and its location:

Benign lesions:

• Observation with regular monitoring
• Cryotherapy to freeze the lesion
• Curettage or laser therapy for cosmetic removal

Malignant or suspicious lesions:

• Surgical removal to prevent spread
• Specialist procedures for high-risk areas
• Topical treatments or therapies for superficial growths

Minor skin surgery is often safe, quick, and effective for removing problematic lesions.

Protecting Your Skin

• Use broad-spectrum sunscreen SPF 30+ daily
• Wear protective clothing and hats
• Seek shade during peak sun hours
• Avoid tanning beds
• Check your skin regularly for new or changing spots

Routine self-checks and professional skin assessments help catch issues early.
