Anatomically, breasts are two well structured and shaped mounds of fat that start to grow on the chest of girls when they hit puberty. The biological objective for women to have breasts is to eventually produce milk to wean her baby. Breast growth can be noticed in some girls as early as age 7 or 8, while in others, it does not start until their late teens or even early 20's.
It is however believed that the timing of these developments is associated with ones own biologic clock, which tells our body to start producing the required levels of female hormones called estrogen. From the moment, the ovaries start to secrete these hormones, the connective tissues in the chest start to accumulate fat. This causes the first appearance of breasts on the chest wall of girls. The duct system in the breasts also begins to grow; these are what will eventually help to produce milk for the expecting mother.
Usually, the first signs of puberty in most girls are associated with the development of the breast. Along with this, one can often expect the onset of pubic hair and hair of the arm pit.
The final size and shape of a girl’s breast vary greatly from being big breast, small breast or even perfect size breast. These pointers are all determined by the heredity of the girl.
Over the years, people have referred to breasts by various terms; however it is the slang that is more popular. Some common slangs are: Tits, Titties, Norks, Jugs, Knockers, Bust, Boobs, Bosoms, Boobies, Baps, Hooters and Melons.
To fully understand the developments of the breasts, it is necessary to first look at the structure of the breasts.
