Abstract
Abstract: Photodynamic therapy (PDT) is a non-invasive treatment of cancer patients who take a photosensitizer and expose their tumours to light after administering it topically or intravenously. Understanding apoptosis under oxidative conditions makes PDT a more effective treatment. Tissue oxygen, tumour-selective photosensitizer dyes, and customised lighting are needed to create fatal reactive oxygen species (ROS) in cancer. PDT has decreased morbidity and improved survival and status of life when used in combination with other treatments, especially in early-stage malignant tumours. Using interstitial light delivery, PDT can cure large, hidden tumours that would otherwise necessitate extensive surgery. This overview describes the foundational historical work that has shaped the technique since the early 1900s. PDT's efficacy is also increased by innovative photosensitizers and tweaks that increase tumour selectivity. Adverse effects and treatment during therapy, as well as innovative PDT-based applications, are explored in this review. Finally, PDT research gaps and clinical trials have been identified as potential issues.
