DNA repair discoveries hold promise for new approaches to cancer treatment

DNA can be damaged by toxins, radiation, or even normal cell division, but human cells must continually fix DNA breaks to survive. In cells that cannot repair DNA effectively, changes (mutations) can occur that lead to cancer. Most cells rely on a system called homologous recombination or HR, which uses proteins called BRCA1 and BRCA2 for accurate DNA repair.
