Tumor Complexity Prompts Caution About Sequencing

Abstract

In mid-September, the National Cancer Institute and the National Human Genome Research Institute announced a $100 million effort to sequence the genomes of lung, brain, and ovarian cancer, the three cancers with the best tissue repositories. It is just the first step in the larger endeavor called the Cancer Genome Atlas, a $1.5 billion attempt to find all the mutations in cancer.
