Moles are clusters of pigmented cells which typically pose no threat when stable and symmetrical. However, when a mole changes shape, color, or size—or worse, itches, bleeds, or crusts over—it could be an indication of melanoma or another type of skin cancer. Early detection is critical for successful treatment.
The ABCDE Rule for Identifying Suspicious Moles
In order to help distinguish between harmless moles and those worth investigating, dermatologists recommend the ABCDE rule :
– Asymmetry : One half of the mole doesn’t match the other.
– Border : Edges are irregular, blurred, or ragged.
– Color : Shades vary within the mole (brown, black, red, white, or blue).
– Diameter : Larger than 6 millimeters (about the size of a pencil eraser).
– Evolving : Changes in appearance over time.
In case any mole fits these criteria, consult a doctor immediately.
