Researchers from the Peninsula Medical School in Cornwall, UK, have modified a photodynamic therapy (PDT) treatment that combines a topically applied cream with visible light to destroy cancer cells while leaving surrounding tissue unharmed. The cream is applied directly to skin cancers and pre-cancers, which then naturally produces a photosensitive drug. A special red light is then shone on the tumour a few hours later, to activate this light sensitive compound. This results in cellular damage and the destruction of the tumour. This technique results in reduced scarring and little or no damage to the surrounding healthy cells. read more
