Melanoma is the most dangerous type because it can spread rapidly to other organs. It often appears as a mole with irregular edges, uneven colors, or changes in size and shape. Detecting it early dramatically increases survival rates.
To help identify melanoma, dermatologists use the ABCDE rule—Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolving appearance. Any mole or spot that fits these descriptions should be checked by a professional right away.
Nodular melanoma, a fast-growing subtype, can develop suddenly and may not follow the usual ABCDE pattern. Because it progresses quickly, prompt evaluation is essential.
