How can I tell the difference between seborrheic keratosis and melanoma?
Seborrheic keratosis typically has a waxy, well-defined, “stuck-on” appearance with uniform color. In contrast, melanoma often displays irregular borders, multiple colors, asymmetry, and rapid changes in size or shape. Dermatologists use the ABCDE rule to identify suspicious lesions. Any unusual or evolving growth should be examined promptly.
When should I see a doctor for seborrheic keratosis?
You should consult a dermatologist if a lesion changes rapidly, bleeds, becomes painful, or appears significantly different from others on your skin. Sudden outbreaks of multiple growths should also be evaluated. Professional assessment ensures accurate diagnosis and rules out skin cancer.
