Non-Healing Mole — Should I Worry?
Quick answer
Yes — get a mole that won't heal checked promptly. Noticing a spot that remains open or bleeds easily is a significant clinical sign that requires professional evaluation soon. While many minor skin injuries heal within a fortnight, a persistent sore or a lesion that repeatedly scabs over and peels away without fully closing is a common warning sign of abnormal cell growth. Most cases identified early are highly treatable and do not lead to serious long-term health complications, but ignoring a non-healing area allows the underlying issue to deepen. You should shift from simple monitoring to an urgent appointment if the spot begins to feel firm like a pearl or starts to ooze without any clear injury. These changes often indicate that the skin architecture is being disrupted by something more serious than a simple irritation, making a prompt biopsy the safest path forward to ensure your peace of mind. Next step: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).

What to look for
Visual red flags often include a peculiar shiny or pearly border that catches the light differently than the surrounding healthy tissue. You should also watch for irregular jagged edges where the pigment seems to leak into the skin rather than staying within a clear boundary. Another concerning feature is the presence of multiple colors like blue, black, and tan mixing together in a chaotic pattern across the surface. Pay close attention if the mole develops a sudden thickness or a raised, crusty texture that feels rough to the touch. Tiny blood vessels might also become visible on the surface, appearing like thin red spider webs. If the spot looks significantly different from every other mark on your body or exhibits these specific surface changes, it is time to have a specialist take a closer look.
Most likely causes
Common mole (naevus)
Symmetrical, uniformly coloured, stable over years.
Atypical (dysplastic) mole
Larger or irregular mole — higher melanoma risk but usually benign.
Melanoma
Skin cancer that may arise in an existing mole or as a brand new spot.
Congenital naevus
Mole present from birth — most are harmless but warrant monitoring.

The safest next step is: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).
Key red flags include: ABCDE: Asymmetry, Border irregularity, Colour variation, Diameter >6 mm, Evolution; Itching, bleeding or crusting in a previously stable mole; The "ugly duckling" — a mole that looks different from your others; New mole appearing after age 40. Any of these alone is reason to book a dermatology assessment promptly.
The most common causes are Common mole (naevus), Atypical (dysplastic) mole, Melanoma, Congenital naevus. Most are benign, but any sore, scab or ulcer that fails to fully heal within 4–6 weeks deserves dermatology review — non-healing is a classic feature of basal and squamous cell carcinoma.
Seek same-week medical review (same day if also bleeding heavily, spreading or with fever). Seek same-day care for: heavy bleeding, rapidly spreading redness with fever, severe pain, or a new black streak under a fingernail or toenail.
