|Title:||Method of detection of malignant and non-malignant lesions by photochemotherapy of protoporphyrin IX percursors|
|Abstract:||A method of detecting and treating malignant and nonmalignant tissue abnormalities and lesions of the skin, conjunctives, respiratory, digestive and vaginal mucosa; endometrium and urothelium in which 5-aminolevulinic acid is administered to the patient in an amount sufficient to induce synthesis of protoporphyrin IX in the lesions, followed by exposure of the treated lesion to a photoactivating light in the range 350-640 nm.|

1. A method for detecting malignant and non-malignant tissue abnormalities and lesions of the skin, mucosa, endometrium and urothelium in a patient, comprising administering to said
patient an effective amount of a precursor of protoporphyrin IX in the biosynthetic pathway for heme so as to induce synthesis of protoporphyrin IX preferentially in said abnormalities and lesions, exposing said patient to light having a wavelength
within the absorbance spectrum of said protoporphyrin IX to thereby induce fluorescence in said abnormalities or lesions, and detecting said fluorescence.
2. The method of claim 1 wherein said precursor is 5-aminolevulinic acid.
