Thelarche is when female humans develop full breasts. It happens from about 9-15 years of age today, although in the past it began at age 12. This usually begins when girls are about 9[1]. A lump that is a bit hard appears in each breast under the areola, which is the dark ring around the nipple. The lump in one breast may grow before the other one.[2] This is called breast budding.[3] Within 6-12 months, both breasts will have started growing. The swelling can be felt and seen outside the edges of the areolae. About 1 and a half to 2 years after the breasts first start growing, they are close to the shape and size of an adult woman's breasts. The nipple and areola may be on a smaller mound on each breast. This small mound usually goes away when each breast is fully grown.[4] Breast size depends on the body's amount of fat.[3][5]
