The efficacy of a photolyase-based device on the cancerization field: a clinical and thermographic study.

Background At skin level, a cancerization field (CF) indicates some chronically photoexposed areas in which, besides a primary tumor, histological or biomolecular modifications without clinical signs are present. Active telethermography (ATT) allows us to observe the imaging of a hyperthermic halo (HH) surrounding the tumor . The Authors hypothesize HH as a possible expression of CF.
