Improving diagnosis
• Assess risk factors and stratify risk • Take time to examine the skin as a whole and not just the
lesion • Take note of the ugly duckling
• Use a bright light, or natural light, and magnifying glass • Touch
• Photograph, measure and bring back at 3 months and 6 months
• Dermoscopy?????? Needs training but I wouldn’t be without mine!
