Light-absorbing particles, called photosensitizers, are found in plants and animals, including people. There are several photosensitizers, yet many have the ability to take in a specific series of light wavelengths.
When the photosensitizer is revealed to a light with a coordinating spooky range, it's converted from its ground state into a fired up singlet state. This allows it to transfer power to molecular oxygen, producing singlet oxygen and free radicals that moderate mobile toxicity.
The Light
Throughout treatment, an unique light is radiated on the location where the photosensitizer was applied. This light turns on the medicine and destroys cancer cells or precancerous cells that it has actually targeted.

The photosensitizer is delivered into the skin through topical, oral or intravenous administration. It is absorbed by the tumor cells and activated when exposed to light of a particular wavelength. This sets off a sequence of photochemical reactions that generates reactive oxygen species (ROS) that damages growth tissue and kill cancer cells.
PDT is most often used to deal with actinic keratoses and sitting squamous cell carcinoma (Bowen disease). It can also be made use of to deal with various other kinds of skin cancer, including superficial basic cell cancer. It can be utilized alone or with other therapies, such as surgical procedure or radiation.
