What is "photodynamic therapy"?

Photodynamic therapy (PDT) is a medical treatment that uses a light-sensitive substance and light to destroy abnormal cells or microbes. The process involves giving the substance, which is absorbed by target cells or germs. When exposed to specific light wavelengths, the substance becomes activated and produces reactive oxygen species that destroy the targeted cells or microbes. Photodynamic therapy is used to treat various conditions, including certain types of cancer such as skin cancer, skin disorders like acne and psoriasis, and infections caused by bacteria or fungi. It is valued for its targeted approach and minimal damage to surrounding healthy tissue compared to traditional treatments.

Example

Photodynamic therapy is an innovative treatment for certain types of cancer, using light-sensitive drugs and a specific wavelength of light to destroy cancer cells.

The dermatologist recommended photodynamic therapy to treat her actinic keratosis, a precancerous skin condition.

During photodynamic therapy, the patient received a photosensitizing agent, which was activated by a special light to target and kill abnormal cells.
