Copy Number Alteration Found to be Associated with Cancer Mortality

Scientists have discovered a link between certain changes in the genome of a tumor and increased chances of death across multiple types of cancer. Their study (“ Tumor copy number alteration burden is a pan-cancer prognostic factor associated with recurrence and death ”), published in  eLife , suggests the percentage of a tumor's genome with copy number alteration (CNA) is associated with mortality in a range of cancers. CNA refers to the fact that a genome can co
