Photodynamic therapy: a distinct therapeutic modality

Photodynamic therapy (PDT) is an innovative treatment modality that utilizes a combination of photosensitizing agent, specific wavelengths light, and molecular oxygen to selectively target destroy abnormal cells or tissues while sparing healthy surrounding structures. This approach has gained significant attention in the medical field due its potential provide effective less invasive options for various conditions. The development PDT was driven by need treatments overcome limitations conventional modalities such as surgery, radiation therapy, chemotherapy. offers several benefits over these approaches, including ability targeted reduced side effects, minimal damage tissues, versatility treating different diseases. One key advantages selectivity. By utilizing photosensitizers accumulate diseased cells, can precisely affected tissue minimizing tissues. selectivity allows focused treatment, reducing unnecessary harm Furthermore, faster recovery times potentially better cosmetic outcomes compared it does not require extensive incisions removal Additionally, localized nature minimizes systemic toxicity long-term complications, making well-tolerated option. demonstrated efficacy fields, oncology, dermatology, ophthalmology. It been used treat types cancers, skin, lung, oesophagal, bladder cancer, well manage conditions like age-related macular degeneration certain dermatological disorders. article reviewed development, mechanism, applications
