๐ก Photodynamic Therapy (PDT) – Light-Activated Healing
Photodynamic Therapy (PDT) is a non-invasive treatment that uses a combination of light-sensitive drugs (photosensitizers) and a specific light source to destroy abnormal or diseased cells—commonly used in cancer, skin disorders, and age-related macular degeneration (AMD).
๐ฌ How It Works:
-
Photosensitizer Administration – Drug is applied to the skin or injected.
-
Incubation Period – Drug accumulates in target cells.
-
Light Activation – A specific wavelength of light activates the drug.
-
Cell Destruction – Activated drug produces reactive oxygen species that kill abnormal cells.
๐ Key Applications:
-
Dermatology: Actinic keratosis, acne, basal cell carcinoma
-
Oncology: Esophageal, lung, bladder, and cervical cancers
-
Ophthalmology: Age-related macular degeneration
-
Dentistry: Periodontal infections and oral cancers
๐ Benefits:
-
Minimally invasive
-
Targeted with minimal damage to healthy tissue
-
Repeatable with fewer side effects than traditional radiation or chemotherapy
