Bioinformatics
Identifying the genetic differences among normal cells, precancerous cells, and cancer cells, will contribute to our understanding of cancer as it 
                 fosters the discovery of genes that directly cause cancer 
                 provides us with a way to identify early precancerous cells and thus
                 enhances our methods for early detection 
                 improves our ability to match patients with appropriate treatment
