The ABCDE Rule (for melanoma detection)

The ABCDE Rule is a guide to help identify potential melanoma, a serious type of skin cancer. - **A for Asymmetry:** One half of the spot doesn't match the other in shape or size. - **B for Border:** Edges are irregular, scalloped, or poorly defined. - **C for Color:** The color varies within the lesion, including shades of brown, black, or even patches of pink, red, or white. - **D for Diameter:** The spot is larger than about 6 millimeters (roughly the size of a pencil eraser), though melanomas can be smaller. - **E for Evolving:** Any change in size, shape, color, or new symptoms like itching or bleeding. Regular checks help catch skin changes early.
