As soon as the photosensitizer is exposed to a light with a matching spooky array, it's converted from its ground state into an excited singlet state. This enables it to transfer power to molecular oxygen, creating singlet oxygen and free radicals that mediate mobile poisoning.
The Light
Throughout therapy, a special light is radiated on the location where the photosensitizer was applied. This light activates the medication and ruins cancer cells or precancerous cells that it has actually targeted.

It is absorbed by the lump cells and triggered when subjected to light of a particular wavelength. This triggers a series of photochemical responses that generates reactive oxygen species (ROS) that damages growth tissue and kill cancer cells.
PDT is most often used to treat actinic keratoses and sitting squamous cell cancer (Bowen disease). It can additionally be utilized to treat various other kinds of skin cancer, including superficial basic cell carcinoma. It can be used alone or with various other treatments, such as surgery or radiation.
