In most young women, this mound disappears into the contour of the mature breast (stage 5), although there is so much variation in sizes and shapes of adult breasts that stages 4 and 5 are not always separately identifiable.
Hos de fleste unge kvinder forsvinder denne forhøjning ind i det voksne brysts kontur (5. stadie), men der er så stor variation i voksenbrysters størrelse og form at stadie 4 og 5 ikke altid kan identificeres separat.
