When wearing such a bra, the tissue in the breast mound squeezes out the back and sides of the cups, into the armpits. Over time, this tissue moves more permanently into the areas into which it has been pressed. Bras with a too-large cup may cause tissue migration to the sternum.<ref name=vgcomment>[http://www.venusianglow.com/2012/01/can-breast-tissue-migrate-to-sternum.html#IDComment413815397 ''Venusian Glow'': "Can Breast Tissue Migrate to the Sternum?" - Comment #413815397]</ref> Summary: Please note that all contributions to the Bustyresources Wiki are considered to be released under the CC-BY-SA Cancel Editing help (opens in new window) Retrieved from "https://bustyresources.fandom.com/wiki/Migrated_breast_tissue"
