A detailed search has revealed how the human genome is rearranged in 24 cases of breast cancer. Researchers were astounded by the number and complexity of genomic rearrangements found in some cases. While some breast cancers are relatively undisturbed, others are fractured extensively and then reassembled, with more than 200 rearrangements present. The research highlights that breast cancer is not one but several diseases and could help to make tumor classification and diagnosis more accurate.
