Bleeding Mole — Should I Worry?
Quick answer
Yes — get a mole that bleeds checked promptly. Bleeding from a spot on your skin is often caused by accidental friction or injury, but it becomes a medical concern when it occurs without a clear reason or if the area refuses to heal. While many cases turn out to be harmless growths like a seborrheic keratosis or an irritated wart, a lesion that crusts and oozes spontaneously is a hallmark sign that deeper professional evaluation is needed. The typical outcome for most patients is a simple biopsy followed by observation, though any spot that remains an open sore for more than three weeks should be treated as an urgent priority. You should shift your perspective from monitoring to seeking an immediate appointment if the bleeding is persistent or if the spot feels like it is thickening underneath the surface. This proactive approach ensures that even a rare melanoma is addressed in its most treatable stage. Next step: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).

What to look for
Observing the specific physical traits of the lesion helps determine the level of risk. Pay close attention to asymmetry, where one half of the spot does not match the other in shape or height. You should also watch for a strange mixing of colors such as dark blues or charcoal grays blending with pale pinks within the same border. Another concerning sign is the presence of satellite spots, which are smaller marks appearing near the main lesion, or a sudden change in texture that makes the skin feel hard and fixed rather than soft and moveable. If the surface looks shiny or develops a pearly appearance along with the bleeding, these are significant indicators of skin cancer. Tracking these visible details allows for a much more accurate assessment during a clinical exam, ensuring that no subtle changes are overlooked.
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 a lesion that bleeds without trauma — or that scabs, heals, then bleeds again — is one of the most important red flags for non-melanoma and melanoma skin cancers.
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.
