SpectraCure is developing a treatment system for the elimination of internal solid cancer tumors. We initially focus on recurrent prostate cancer, with the hope of being able to treat other cancers as primary prostate cancer in the future. The method builds an in-house developed and patented treatment system – a laser unit that performs PDT treatment and treats the prostate itself in combination with a patented dose planning platform IDOSE®. The method makes it possible to control the laser light dose so that the tumor is exposed to an optimal dose in order to achieve a sufficient treatment effect. The treatment system has the potential to make interstitial PDT treatment accurate, precise and safe for each patient.
