Double trouble: Cells with duplicate genomes can trigger tumors

..." cells also duplicate a cell structure called the centrosome that plays a role in maintaining a stable genome. The extra centrosomes may be at the root of the cancer-triggering process. Once the genetic instability sets in, tumors "evolve " by losing, gaining and rearranging chromosomes. Late-stage tumors co...
