Skin Cancer Screening: Diagnosis & Biopsy of Suspicious Moles & Skin Lesions
A clear guide to skin cancer screening, including the evaluation of suspicious moles and skin lesions, and how early detection guides treatment.
Treatment usually begins with
Skin Examination
Dermoscopy
Biopsy if Needed
Coordinated Treatment Planning
Evaluation begins with a detailed skin examination and dermoscopy, with a biopsy performed for any lesion that needs further assessment.
You may need this evaluated if...
A dermatology evaluation is recommended when you notice:
- A mole that has changed in size, shape or colour
- A new, unusual-looking spot on the skin
- A sore that doesn't heal within several weeks
- A mole that is asymmetric, has an irregular border, or is larger than a pencil eraser
Most skin lesions evaluated turn out to be benign, and when skin cancer is found, early detection through screening leads to excellent treatment outcomes in the great majority of cases.
What is Skin Cancer Screening & Suspicious Moles?
Skin cancer screening evaluates moles and skin lesions for signs of concern, using a structured examination and dermoscopy, with early detection significantly improving the outcome when skin cancer is found.
Early Detection Changes Outcomes
Skin cancers caught early are generally highly treatable, making regular screening valuable, especially for those at higher risk.
The ABCDE Rule Guides Self-Checks
Asymmetry, irregular Borders, varied Colour, large Diameter and Evolution over time are signs to watch for in a mole.
Dermoscopy Aids Accurate Assessment
A magnified skin examination helps distinguish benign moles from those needing biopsy.
Not Every Suspicious-Looking Mole Is Cancer
Many moles that look unusual turn out to be benign on closer examination or biopsy.
Common Symptoms
- A mole that has changed in size, shape or colour
- A new, unusual skin growth
- A sore or lesion that doesn't heal
- Itching, bleeding or crusting of a skin lesion
What Increases Your Risk
A combination of genetic, environmental and lifestyle factors can increase the likelihood of this skin condition.
How It Is Diagnosed
A dermatological examination, often supported by targeted tests, confirms the diagnosis and guides treatment.
Full Skin Examination
A dermatologist examines the skin systematically for lesions of concern.
Dermoscopy
A magnified examination assesses the specific features of a mole or lesion.
Skin Biopsy
Removes a sample of a suspicious lesion for laboratory examination.
Follow-up Monitoring
Photographic tracking of moles over time helps detect changes early.
Treatment Approaches
Medical & Topical Management
- Regular self-examination guidance using the ABCDE rule
- Scheduled follow-up for monitoring moles of uncertain significance
- Sun protection guidance to reduce future risk
Procedural & Dermato-Surgical Care
Excision of a confirmed or strongly suspected skin cancer removes the lesion, with further treatment coordinated based on the biopsy result.
Treatment is tailored to your specific skin type, severity and how you respond, not a one-size-fits-all regimen.
Know When to Act
Recognising these signs early and seeking timely dermatology care helps prevent scarring and long-term skin damage.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- A stable, long-standing mole with no recent change, seeking a routine check
Seek Urgent Care
Reach out for urgent care if you notice any of the following.
- A mole with rapid change, bleeding, or a non-healing sore needs prompt evaluation
