Homonym: PDT (Time)
PDT, or Photodynamic Therapy, is a medical treatment that uses light-sensitive drugs and a specific type of light to kill cancer cells. The drugs, known as photosensitizers, are absorbed by the cancerous tissue. When exposed to light, these drugs become activated and produce a form of oxygen that destroys nearby cells.
This therapy is often used for certain types of skin cancer and other localized tumors. PDT is considered less invasive than traditional surgery and can minimize damage to surrounding healthy tissue. It is also used in treating conditions like acne and age-related macular degeneration.
