Once the photosensitizer is revealed to a light with a matching spectral array, it's transformed 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 applied. This light activates the medication and ruins cancer cells or precancerous cells that it has targeted.

The photosensitizer is delivered right into the skin via topical, oral or intravenous management. It is absorbed by the lump cells and activated when subjected to light of a details wavelength. This sets off a series of photochemical reactions that creates reactive oxygen types (ROS) that damages tumor cells and kill cancer cells.
PDT is usually made use of to treat actinic keratoses and sitting squamous cell carcinoma (Bowen illness). It can additionally be used to deal with 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 treatment or radiation. It can also shrink growths in the lungs, permitting surgery or other therapy to be safe and efficient.
The Therapy
PDT works finest in little abnormal areas of cells that a light source can reach, such as the skin, eyes, mouth or food pipeline (oesophagus) and lungs. It is likewise made use of to treat precancerous growths, such as actinic keratoses, which are sun-damaged cells that can become cancer cells.
