a light-activated treatment to target and destroy abnormal cells, such as cancer cells
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.
