Once the photosensitizer is exposed to a light with a coordinating spooky range, it's converted from its ground state right into a fired up singlet state. This enables it to transfer energy to molecular oxygen, creating singlet oxygen and free radicals that mediate mobile toxicity.
The Light
During treatment, an unique light is shined on the location where the photosensitizer was applied. This light turns on the medication and damages cancer cells or precancerous cells that it has targeted.
The medications that are used in photodynamic treatment have different absorption residential or commercial properties and some of them may take hours to leave normal cells however stay much longer in cancer or precancer cells.

This sets off a sequence of photochemical responses that creates reactive oxygen species (ROS) that damage tumor tissue and kill cancer cells.
PDT is most often made use of to deal with actinic keratoses and in situ squamous cell cancer (Bowen illness). It can also be utilized to treat other kinds of skin cancer cells, including shallow basal cell cancer. It can be made use of alone or with various other treatments, such as surgery or radiation.
