• The dermoscopy 3-point checklist for early detection of skin cancer is fairly easy to learn and has a high sensitivity for melanoma. The 3-point checklist has been designed to allow non-experts not to miss detection of melanomas • Asymmetry: asymmetry of color and structure in one or two perpendicular axes • Atypical network: pigment network with irregular holes and thick lines • Blue-white structures: any type of blue and/or white color, i.e. combination of blue-white veil and regression structures
