PDT has been approved for the treatment of various cancers, including skin, lung, and esophageal cancers. It is also used for non-oncological conditions such as age-related macular degeneration and bacterial infections. The non-invasive nature and the ability to target specific tissues make PDT a versatile treatment option. Researchers are continually exploring new applications, such as treating multidrug-resistant bacterial infections and combining PDT with other therapies to improve outcomes.
