Derma mapping uses high-resolution photographs to take an inventory of all lesions on your body. Lesions are any type of change to skin that used to be normal and healthy. Lesions can be both cancerous (malignant) and non-cancerous (benign).
Derma mapping pictures provide a way to track changes on your skin if you have a large number of unusual moles or if you have a history of skin cancer.
Because it shows a history of changes to your skin over time, derma mapping can also help dermatologists diagnose melanoma and skin cancer earlier.
