Traumatised a mole: what should you do and can it cause melanoma?
A single mechanical injury to a mole is not itself evidence of melanoma and is not regarded as a proven cause of melanoma. More important is how the lesion looked before the injury and what happens afterwards.
Trauma to a mole ≠ a melanoma diagnosis
In this Ukrainian-language video I explain why accidental injury to a naevus does not itself mean malignant transformation and which subsequent changes deserve attention.
What to do immediately after an injury
- stop bleeding with a clean dressing and gentle pressure;
- clean the area carefully and do not try to burn or cut away the remaining lesion yourself;
- allow a superficial wound to heal and watch the area;
- if the lesion was suspicious before the injury or remains concerning, arrange an in-person assessment.
When to seek assessment
Arrange review if the lesion keeps bleeding or bleeds again without a new injury, does not heal, clearly changes in shape, colour or size, becomes itchy or painful, or looks different from your other moles.
What helps assess risk
The ABCDE rule can be used as a self-check prompt: asymmetry, border, colour, diameter and evolution. Final clinical assessment is made by a clinician and may include dermoscopy and biopsy when indicated.
