A bad mole, potentially indicating melanoma, often exhibits characteristics summarized by the acronym ABCDE: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolving size, shape, or color.
To better understand what to look for, consider these details:
-
A - Asymmetry: One half of the mole does not match the other half. Healthy moles are typically symmetrical.
-
B - Border Irregularity: The edges of the mole are ragged, notched, blurred, or indistinct. The pigment may spread into the surrounding skin. Healthy moles typically have smooth, well-defined borders.
-
C - Color Variation: The mole exhibits uneven color, including shades of black, brown, and tan. Red, white, pink, or blue colors may also be present. Healthy moles typically have a uniform color.
-
D - Diameter: The mole is generally larger than 6 millimeters (about ΒΌ inch or the size of a pencil eraser). While smaller moles can also be problematic, larger size increases concern.
-
E - Evolving: The mole is changing in size, shape, color, or elevation; a new symptom, such as bleeding, itching, or crusting, appears. This is perhaps the most important sign. Any noticeable change warrants immediate attention.
Key Indicators Summarized in a Table:
| Feature | Benign (Good) Mole | Suspicious (Bad) Mole |
|---|---|---|
| Asymmetry | Symmetrical | Asymmetrical |
| Border | Smooth, well-defined | Irregular, ragged, notched, blurred |
| Color | Uniform color (usually brown) | Varied colors (black, brown, tan, red, white, blue) |
| Diameter | Usually smaller than 6mm | Usually larger than 6mm |
| Evolution | Stable; no significant changes over time | Changing in size, shape, color; new symptoms appearing |
It is crucial to consult a dermatologist if you notice any of these characteristics in a mole. Early detection and treatment are essential for successful melanoma management. Self-exams are an important tool, but professional evaluation is needed for diagnosis.
