Scientists discover new DNA regions associated with three cancers
Los Angeles Times

A massive gene-hunting effort involving hundreds of scientists has identified 74 newly discovered regions of DNA that are associated with breast, ovarian and prostate cancers — diseases that strike about half a million Americans every year.

The international project, known as the Collaborative Oncological Gene-environment Study, or COGS, nearly doubled the number of genetic markers known to be linked with the three cancers, scientists reported Wednesday.
