A major factor in monitoring change is having a consistent method of documentation. Without a visual record, it is difficult for both doctors and patients to really know with confidence whether or not a lesion has changed. As most of the early signs are visual, photography is a particularly good method of documentation. Numerous clinical studies have proven the value of overall body photography in the early diagnosis of melanoma. Recent melanoma consensus conferences have recommended the use of photography in melanoma surveillance for high-risk groups. Photography helps to reduce the unnecessary removal of harmless moles. It is more cost effective than prophylactic excisions. Photographs can help save time during patient review, as they provide increased certainty. Imaging can provide the anxious patient with peace of mind and they can use them for self-monitoring between visits.
