Exploring the field of cancer genomics can give a researcher without a sturdy footing in bioinformatics a bad case of information overload. But the potential payoff is high. Cancer researchers have been amassing data on small mutations, copy number variations, epigenetic changes, expression level differences, and clinical features for a number of cancer types since long before the first whole cancer genome sequence (of an acute myeloid leukemia) was completed in 2008. That means researchers diving into the fray today will have more—and higher quality—information at their fingertips than ever before. Yet navigating it won’t be easy, says William Hahn, an associate professor of medicine who studies a number of cancers at the Dana-Farber Cancer Institute in Boston. “It’s a huge challenge to know what’s ...
