Discovery about how cancer cells evade immune defenses inspires new treatment approach

Cancer cells are known for spreading genetic chaos. As cancer cells divide, DNA segments and even whole chromosomes can be duplicated, mutated, or lost altogether. This is called chromosomal instability, and scientists at Memorial Sloan Kettering have learned that it is associated with cancer’s aggressiveness. The more unstable chromosomes are, the more likely that bits of DNA from these chromosomes will end up where they don’t belong: outside of a cell’s central nucleus and floating in the cytoplasm.
