Photodynamic therapy uses photosensitizing topical medication that is activated by a light source. The photosensitizing agent is put in the bloodstream through a vein or placed on the skin and soaks into the cancer cells. A light of a specific wavelength is then applied that makes the agent react with oxygen, forming a chemical that destroys the cancer cells.
