What characteristic would indicate a potential skin cancer lesion?

The presence of uneven edges is a critical characteristic that can indicate a potential skin cancer lesion. Skin lesions that exhibit irregular or jagged borders are often more concerning, as they may suggest malignancy. In the context of skin cancer, particularly melanoma, one of the warning signs is the asymmetry and irregularity of the borders of a mole or skin growth. When borders are uneven, it signifies a deviation from the normal characteristics of benign moles, which typically have smooth, well-defined edges.

While symmetrical borders and uniform color are characteristics more commonly associated with benign lesions, their absence can be a red flag in terms of skin cancer assessment. A small size alone does not provide sufficient context to rule out cancer, as skin cancer can vary widely in size and still be present. Therefore, the key takeaway is that the uneven edges of a lesion can warrant further investigation, making it a significant indicator of potential skin cancer.
