Moles, also known as clusters of pigmented skin cells, are generally harmless and common.
As long as they remain symmetrical, maintain a consistent color, and do not change in size or texture, there’s usually no cause for concern.
However, when a mole begins to shift in shape, deepen in color, or grow rapidly — or worse, starts to itch, bleed, or scab — it can be an early sign of melanoma or another form of skin malignancy.
Catching such changes early can be life-saving, as the success of treatment is closely tied to how promptly the issue is identified.
Dermatologists suggest a simple yet effective guideline to recognize questionable moles — the ABCDE method.
This involves checking if both halves of the mole mirror each other. Benign moles are typically round or oval with clear symmetry.
If one side noticeably differs from the other, it may warrant professional attention. Likewise, edges should be smooth — blurred or jagged borders can be alarming.
Color should be uniform — the presence of multiple tones like black, reddish, bluish, or whitish hues calls for further examination.
When it comes to size, anything over 6 millimeters — roughly the diameter of a pencil eraser — should be assessed.
The most crucial factor, however, is change over time — any increase in size, shift in color, alteration in surface, or new symptoms should raise concern.
Though moles often get the spotlight, other types of skin irregularities should also not be overlooked.
Actinic keratosis, for example, appears as a rough, flaky area due to prolonged sun exposure and may develop into squamous cell carcinoma.
Basal cell carcinoma usually presents as a shiny or waxy bump, most often seen on sun-exposed regions like the face, neck, or shoulders.
Squamous cell carcinoma tends to emerge as a firm, reddish bump or a flat patch that peels and refuses to heal.
Seborrheic keratosis, although benign, often appears as a dark brown or blackish growth that looks stuck onto the skin — its odd texture can resemble something more dangerous.
Watch out for any skin lesion that appears suddenly or starts growing quickly. If the area becomes itchy, sore, or begins to bleed, it deserves attention.
Also, if the pigmentation starts to extend beyond the mole’s border or a persistent open wound develops, medical evaluation is necessary.
One of the most proactive steps you can take is to perform regular self-examinations — ideally once a month.
With good lighting and a mirror, carefully inspect your entire body, including less visible areas like the scalp, soles, back, and under nails.
The goal is to spot any new formations or transformations early.
If you notice anything unfamiliar or evolving, book an appointment with a dermatologist who can examine it more closely and, if needed, perform a biopsy or remove the area entirely.
Shielding your skin from UV radiation is also essential. Apply sunscreen with SPF 30 or higher daily, even on cloudy days.
Avoid direct sunlight during peak hours — typically between 10 a.m. and 4 p.m. — and wear hats, sunglasses, and protective clothing.
Tanning beds are particularly risky, increasing the chances of melanoma by as much as 75%.
A real-life example emphasizes the importance of early detection. Sabina, a 42-year-old schoolteacher, ignored a mole on her arm for years, assuming it was an age-related change.
Over time, the mole darkened and became irregular in shape. When she finally visited a doctor, she was diagnosed with melanoma.
Thankfully, because she acted before it spread, the growth was removed entirely in time.
Now Sabina urges others to be vigilant: “If you see anything unusual on your skin, don’t wait. A small step can save your life.”
Skin cancer doesn’t discriminate, but staying informed and paying attention gives you the power to protect yourself.
Your body communicates with you — the key is whether you’re ready to listen.
