The Cancer Genome Atlas: The Genetic Basis of Cancer This video is one in a series of videos from The Cancer Genome Atlas (TCGA) project, explaining TCGA's approach to determining the important genomic changes that lead to cancer. TCGA researchers, Drs. Richard Gibbs, Peter Laird, Stacey Gabriel and Neil Hayes, talk about the difference between a normal cell and cancer cell and how understanding the changes in DNA that cause cancer can help doctors develop better treatments. The Cancer Genome Atlas is a comprehensive and coordinated effort supported by the National Cancer Institute and the National Human Genome Research Institute to accelerate our understanding of the genetics of cancer using innovative genome analysis technologies.
