Summary

Description
English:
Title Photodynamic Therapy (Red)
Description The procedure of photodynamic therapy. In this therapy, patients are injected with a light-activated drug called a photosensitizer which makes cells in their body sensitive to light. The drug is selectively retained by cancer cells as compared with normal tissue. Doctors then use fiber-optic probes to expose the cancer to laser light. This activates the photosensitizer and produces a toxic reaction that destroys the tumor without irreparably damaging the surrounding normal cells.
