Record gene haul points to better cancer screening

LONDON, Mar 28:  New research has nearly doubled the number of genetic variations implicated in breast, prostate and ovarian cancer, offering fresh avenues for screening at-risk patients and, potentially, developing better drugs. The bumper haul of 74 gene changes that can increase risks for the three hormone-related cancers, announced by scientists on Wednesday, is the result of the largest ever study of its kind. (agencies)
