When the photosensitizer is subjected to a light with a matching spooky variety, it's converted from its ground state right into an ecstatic singlet state. This allows it to transfer power to molecular oxygen, producing singlet oxygen and totally free radicals that mediate mobile toxicity.
The Light
Throughout therapy, a special light is shined on the location where the photosensitizer was applied. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.

The photosensitizer is supplied into the skin via topical, oral or intravenous management. It is taken in by the lump cells and activated when revealed to light of a particular wavelength. This triggers a series of photochemical responses that produces responsive oxygen species (ROS) that damages tumor cells and eliminate cancer cells.
PDT is usually made use of to treat actinic keratoses and sitting squamous cell carcinoma (Bowen illness). It can additionally be utilized to deal with other kinds of skin cancer cells, including surface basal cell cancer. It can be used alone or with various other treatments, such as surgical procedure or radiation.
