Light Is the Newest Method For Cancer Treatment

Scientists are working on a potential, new type of chemotherapy that uses light to trigger the treatment.

Researchers at Purdue University have developed a group of metal-based compounds that are only damaging to cells in a specific location, such as a tumor, when light is shined on them.

"Only when the light is turned on is there going to be toxicity, and only where the light impacts the body will there be toxicity," says Harry Morrison, of Purdue University. This keeps cells away from the light source remain unharmed.

Dr. Morrison says it's working on lab animals. The next step is to figure out the best way to deliver light inside the human body and researchers are hopeful that someday, light might offer new cancer treatments without the unpleasant side effects we see today.
