Resumen de Gene trawl reveals myriad cancer risks
In the largest study of its kind, an international team revealed more than 80 gene variants that raise the risk of breast, prostate and ovarian cancers. The gene trawls were coordinated at hundreds of labs by the international Collaborative Oncological Gene-environment Study. Although each variant raises the risk of cancer by only a percent or so, the effects add up, so the more variants a person has, the greater the likelihood they will develop cancer, says Douglas Easton of the University of Cambridge and lead author of one of the papers reporting the variants.
