Photodynamic therapy in oncology: Present and future

Abstract

There is progress in applying photodynamic therapy in cancer clinic during the last decade. The promising direction to develop this way of treatment is the use of photosensitizers with given characteristics. It is based on a local activation of a photosensitizer in a cancer tissue by using luminous radiation of an appropriate wave length to launch photochemical reaction following the atypical cells’ destruction. In spite of a successful experience of using photodynamic therapy in different areas of medicine, not all its opportunities are studied. There are general information in this literature survey about the use of photodynamic therapy and its perspectives in oncology.
