A large-scale, worldwide research effort has matched up more genetic traits to certain kinds of cancer.
FOX News Radio's Chris Foster explains:
DNA testing finds dozens of markers in people's genes tied to breast, ovarian and prostate cancer. More than 100 institutions around the world - testing 200,000 people - sharing the results.
The research doubles the known list of risk markers for those cancers. It could lead to tests showing which people would benefit most from screenings like mammograms and prostate biopsies; down the road, maybe better treatments for those cancers as more is discovered about their biological basis.
