Non-Healing Brown Spot — Should I Worry?
Quick answer
Yes — get a brown spot that won't heal checked promptly. Persistent marks that refuse to mend deserve close attention because skin tissue normally repairs itself within a few weeks. When a pigmented area remains open, scabby, or continues to bleed after minor contact, it suggests that the underlying cells are behaving abnormally rather than following a standard healing cycle. While many such marks turn out to be harmless age spots or irritated growths, the lack of resolution is a clinical red flag. You should generally feel comfortable monitoring a stable lesion that shows no change over months, but the situation becomes urgent if the spot begins to expand rapidly or develops a thick, pearl-like border. Most cases caught early result in a simple procedure with an excellent prognosis, but ignoring a non-healing wound risks allowing a potential melanoma to reach deeper layers of the skin where treatment becomes more complex. Next step: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).

What to look for
Visible clues often begin with a lack of symmetry where one half of the blemish does not mirror the other in shape or thickness. You should also inspect the edges for a blurred or ragged appearance that looks like ink leaking into the surrounding tissue. Pay close attention to the internal palette, as having multiple shades of chocolate, charcoal, or even white and blue inside a single patch is more concerning than a uniform tan. Beyond color, feel for a change in texture such as a localized hardness or a raised bump that feels different from the supple skin nearby. These physical shifts, combined with a tendency for the surface to crust over or ooze fluid without an obvious injury, are primary indicators of cancer that require a professional evaluation by a doctor immediately.
Most likely causes
Seborrhoeic keratosis
Waxy, "stuck-on" benign growth — very common after age 40.
Solar lentigo (sun spot)
Flat brown patch from cumulative UV — usually harmless.
Melanoma
Skin cancer that often presents as a new or changing brown/black spot with irregular borders.
Café-au-lait macule
Uniform light brown patch present from childhood.
Red flags — get reviewed
- •Asymmetric shape or irregular borders (ABCDE)
- •More than one colour within the spot
- •Diameter greater than 6 mm or growing
- •New itch, bleeding or change in any existing brown spot
What you can do while you decide
- ✓Photograph monthly with a coin or ruler for scale
- ✓Use SPF 30+ daily and avoid further tanning
- ✓Avoid DIY removal — it destroys the diagnostic features a dermatologist needs

The safest next step is: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).
Key red flags include: Asymmetric shape or irregular borders (ABCDE); More than one colour within the spot; Diameter greater than 6 mm or growing; New itch, bleeding or change in any existing brown spot. Any of these alone is reason to book a dermatology assessment promptly.
The most common causes are Seborrhoeic keratosis, Solar lentigo (sun spot), Melanoma, Café-au-lait macule. 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.
