Structure of the Developed Breast

Prior to puberty, the structure of the breast tissues are exactly the same in both females and males. Once a girl reaches puberty her ovaries start to produces high amounts of the female sex hormones - estrogen and progesterone. These have direct relevance with the growth and development of a girl's breast tissues.

In the structure of a fully developed breast there are approximately 20 groups of lobes. These are glands that take care of producing milk at the time of pregnancy. Each lobule is in fact, an individual milk producing zone having a small tube leading from it called a ductile. The ductile links up to a wider tube called the ducts, which eventually open on to the surface of the nipples. Overall, the nipples will have about 20 of these duct openings which will activate during pregnancy.

Internal Structure of the Breast


In between the lobules there is a mixture of fatty tissue and tough supporting tissues. This maintains the shape of the breast as there are no muscles or bones making up the structure of the breast. The supporting tissues link up to the muscles of the chest wall underneath.

On the outer surface of the breasts one can find the nipple surrounded by a darker skin called the areola. The color of the areola can differ from one woman to another. It can range from dark shades of browns to a bright fleshy pink. The areola can also differ in size which can range from being extremely small and may not be readily visible or it could even spread to a wide area around the nipple.

I remember I read this article probably two years ago which made me realize my breasts are "constricted or tubular", or according to Medindia, "severely deformed" and "surgery is suggested". Thank you for making the first description I ever read about breasts that resemble mine to be "severely deformed" and suggest surgery. Whoever wrote this article obviously has 0 concern for anyone's self esteem. CHANGE THE WORDING of your description so you don't make any more young girls feel any MORE ashamed than they already are about their "severely deformed breasts". There are a LOT more women with this problem than documented due to the shame and embarrassment involved. Your article makes it 20 times worse. Asshole.

I am 21 and my right nipple has been paining on and off since monday. Previously I thought it was due to my sleeping position but now I find my nipple hard and I'm not sure if that is a lump right underneath my nipple. I have been taking alot of purified butter lately which is high in fat. Please suggest me what could be wrong?

STOP TELLING WOMEN HOW TO FEEL ABOUT THEIR BOOBS! unless they're in pain, or have some disease their breasts ARE perfect. i would rather be a little saggy than make my boobs uncomfortable. you know why? cause i actually appreciate my body. in our culture everyone's constantly worried about how they look instead of enjoying themselves. its a sad, sad thing.

My breasts :[ When a teen, I was quite shy and unaware abt stuff. I'll have to blame my mother, therefore, that she did not make me wear a bra when i hit puberty- which was like at 11-12yrs. When I finally did gather the courage to ASK her for a bra, I was 15 and most of the damage had been done. My breasts grew without support, used to wear a simple chemise beneath my clothes. Now they're like big, SAGGY, with faint stretch marks, and when I look at them, I think of how beautiful they COULD have been, and what a disaster they're now. It's just so so sad.
