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.
Other Types of Skin Growths to Watch For
Though abnormal moles get much attention, there are other growths that shouldn’t be ignored:
– Actinic Keratoses : Rough, scaly patches caused by sun damage; precursors to squamous cell carcinoma.
– Basal Cell Carcinomas : Pearly or waxy bumps, often appearing on sun-exposed areas.
– Squamous Cell Carcinomas : Firm, reddened nodules or flat lesions with crusted surfaces.
– Seborrheic Keratoses : Harmless brown or black growths resembling stuck-on dirt, though sometimes mistaken for cancerous lesions.
Signs That a Skin Growth Is Serious
Below are additional red flags to watch for:
– A growth that suddenly appears or grows rapidly.
– Persistent itching, pain, or bleeding around the area.
