  schema:description "The breast is a tree: fifteen to twenty branching duct systems, each ending in a cluster of milk-making sacs called a lobule. Almost every breast cancer starts at the junction between the smallest ducts and their lobule, which is why the two commonest kinds are called ductal and lobular."@en ;
