Breast and Colon Cancer Genomes Sequenced

JAMA. 2006;296(15):1825-1826. doi:10.1001/jama.296.15.1825

Scientists have analyzed the genetic code for breast and colorectal cancers, finding close to 200 key mutated genes within these cancers (Sjöblom T et al. Sciencexpress. doi:10.1126/science.1133427 [published online September 7, 2006]).

History has shown that simply revealing a cancer's genetic cause—for example, certain well-known mutations within the p53 gene—does not often lead to a cure. But the researchers are confident that finding the genes associated with tumor initiation, growth, and spread can lay the groundwork for studies that could lead to better diagnostics and treatments.
