Photodynamic therapy (PDT) is a technique that has been used for the treatment of tumors, especially in Gynecology. The photodynamic reaction is based on the production of reactive oxygen species after the activation of a photosensitizer. Advantages of the PDT in comparison to the surgical resection are: ambulatory treatment and tissue recovery highly satisfactory, through a non-invasive procedure. The cervical intraepithelial neoplasia (CIN) grades I and II presents potential indications for PDT. The aim of the proposed study is to evaluate the safety and efficacy of the PDT for the diagnostics and treatment of CIN I and II. The equipment and the photosensitizer are produced in Brazil with a representative low cost. It is possible to visualize the fluorescence of the cervix and to treat the lesions, without side effects. The proposed clinical protocol shows great potential to become a public health technique.
