New tech could take light-based cancer treatment deep inside
the body
Photodynamic therapy (PDT) is an effective treatment for
easily accessible tumors such as oral and skin cancer.
But the procedure, which uses lasers to activate special
drugs called photosensitizing agents, isn’t adept at fighting cancer deep
inside the body. Thankfully, that’s changing due to new technology that could
bring PDT into areas of the body which were previously inaccessible.
