Early detection of skin cancer can significantly improve treatment outcomes. Regularly examine your skin for any new moles, changes in existing moles, unusual growths, sores that do not heal, or patches that change in color, size, or shape. The ABCDE rule—Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolving appearance—can help identify suspicious skin changes. Protecting your skin from excessive sun exposure and scheduling routine skin examinations are also important preventive measures.
