Arsenic Helps in Tumor Detection

Researchers at U.T. Southwestern Medical Center are getting better tumor images with a little help from arsenic. 

They bound arsenic to a drug that binds to blood vessels in cancerous tumors.  When the drug with arsenic was injected, it did its job - binding to the tumor's blood vessels and creating a "hot spot" that gave scientists clear images. 

In fact, the images were so clear, the researchers think they might be able to spot secondary tumors that spread from the original tumor.
