medical treatment where blood is treated with UV light
Extracorporeal Photochemotherapy (ECP), also known as Photopheresis, is a medical treatment where a patient's blood is drawn, treated with a photosensitizing agent, exposed to ultraviolet (UV) light, and then returned to the body. This process is used to modulate the immune system and is commonly employed in the treatment of conditions like cutaneous T-cell lymphoma, graft-versus-host disease, and certain autoimmune disorders.
