Drug and Light Join Forces to Fight Precancerous Lesions

Photodynamic therapy has been available for years but generally as two separate components—the drug and the light source. Sagentia and Photocure have combined these technologies into a combination device, called Cevira, to destroy HPV-infected tissue and treat precancerous lesions on the cervix, while preserving healthy tissue. According to Peter Hillemanns, chairman of the department of obstetrics and gynecology at Medical University Hannover (Germany), the device provides the first nonsurgical treatment for HPV and precancerous cervical lesions.
