Photodetection of basal cell carcinoma using methyl 5‐aminolaevulinate‐induced protoporphyrin IX based on fluorescence image analysis

Background.  The preferential accumulation of 5‐aminolaevulinic acid (ALA)‐induced protoporphyrin IX (PpIX) in neoplastic cells supports its potential use in the photodetection of porphyrin fluorescence in tumour cells. Hence, epithelial tumours, including basal cell carcinoma (BCC), might be visualized using the fluorescence of selectively accumulated ALA‐induced PpIX.
