When checking existing moles, what changes should you look for?

When checking existing moles, it is important to assess changes in border and color. The borders of a mole should be smooth and even; irregularities or roughness may indicate potential issues. Changes in color can also be significant, as moles should typically be a uniform color. Variations or the emergence of multiple shades (such as black, brown, red, or white) could suggest that further evaluation is needed, potentially indicating the development of skin cancer, such as melanoma.

Evaluating other characteristics such as size, thickness, shape, texture, moisture, and hydration can provide additional information but are not the primary indicators to watch for. The most critical factors in monitoring moles that could raise concerns are the border and color, making them the focal points of a thorough examination.
