Researchers from University Hospitals (UH) Ireland Cancer Center and Case Western Reserve University School of Medicine are part of a new national study that has analyzed more than 18,000 genes, including 5,000 previously unmapped genes, from breast and colorectal tumors. The study, published online by the journal Science on Oct. 11, shows a great number of genetic differences between breast and colon cancer tumors, leading the researchers to conclude that new drugs must be developed that can hit these newly identified genetic targets in a manner specific to each different individual's tumor.
