Breast growth teenage adult

What age do breasts fully develop? How do breast start to develop? Are my breasts normal? Can I change the way my breasts develop?

Breast development happens in certain stages during a woman's life: first before birth, again at puberty, and later during the childbearing years. This starts with a thickening in the chest area called the mammary ridge or milk line. By the time a baby girl is born, nipples and the beginnings of the milk-duct system have formed. The first thing to develop are lobes, or small subdivisions of breast tissue. Mammary glands develop next and consist of 15 to 24 lobes. Mammary glands are influenced by hormones activated in puberty. Shrinkage involution of the milk ducts is the final major change that happens in the breast tissue.

The teenage years are also called adolescence. During this time, teens will see the greatest amount of growth in height and weight. Adolescence is a time for growth spurts and puberty changes. A teenager may grow several inches in several months followed by a period of very slow growth. Then they may have another growth spurt.

Growth during adolescence is linked to the hormonal changes of puberty. Girls usually enter puberty earlier than boys. The inches and pounds added during adolescence can matter in a big way.
