How breast cancer arises
Researchers trace the origin of certain breast cancers to genomic reshuffling — rearrangement of chromosomes — that activates cancer genes and ignites disease. The finding offers a long-missing explanation for many cases of the disease that remain unexplained by the classical model of breast cancer development. The study shows the sex hormone estrogen — thus far thought to be only a fuel for breast cancer growth — can directly cause tumor-driving genomic rearrangements.
