  Hi Anna
  
  Using visible light as a tool for finding disease in the human body has been researched for a long time, as far back as 19th century! The first success was using ultraviolet light to treat lupus. Radiotherapy is a closely related field, because it also used electromagnetic waves or radiation but these waves are much more powerful than visible light. Radiation from radiotherapy can easily pass through the body, destroying DNA of both healthy and cancerous cells.
