As soon as the photosensitizer is subjected to a light with a matching spectral array, it's converted from its ground state into a fired up singlet state. This allows it to transfer power to molecular oxygen, creating singlet oxygen and totally free radicals that mediate mobile toxicity.
The Light
During therapy, a special light is shined on the location where the photosensitizer was used. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.

The photosensitizer is provided right into the skin with topical, dental or intravenous administration. It is soaked up by the tumor cells and turned on when exposed to light of a certain wavelength. This triggers a series of photochemical responses that produces responsive oxygen species (ROS) that damages tumor tissue and eliminate cancer cells.
PDT is most often utilized to treat actinic keratoses and in situ squamous cell cancer (Bowen disease). It can additionally be used to treat various other types of skin cancer cells, including shallow basic cell carcinoma. It can be utilized alone or with various other treatments, such as surgical procedure or radiation.
