As it has already been mentioned up until the puberty the breasts of both genders remain of the same structure. Though as the puberty comes the female body begins produce such hormones as estrogen and then progesterone, which stimulate the process of sexual maturation. The ovaries begin to get mature, as well as the breasts undergo significant changes: they become bigger and develop more fully for a time period, lasting about 3 to 4 years. In about 2 years after the breasts development has begun, girls start having their menstrual periods. And after functional maturation the teen girl becomes able to produce the milk supply in case of pregnancy and subsequent childbirth.
Although by the time of menstruation the female breasts have not developed in their size completely, the girl will still be able to sustain life in case of a necessity. Therefore, breasts continue their development and they reach their adult size only by about 18th – 23rd birthday. Though, even after that the breast changing process goes on, as the years go by and the level of estrogen and / or progesterone hormones get increased, which can occur either naturally or in case of some synthetic and / or natural supplemental hormonal interference. This kind of an outside hormonal influence may be either from birth control pills, implants or shots; or from human growth hormone, and even from herbal remedies. Yes, such herb as wild yam may be taken with the aim of breast increasing.
Here comes the breast scheme along with its lobules, which get grouped into lobes, adipose, which is also called fatty tissue, milk ducts, connective tissue and the nipple / areola complex, as well as the underlying pectoralis major and ribs. As for the chest wall, it is covered by muscle and muscle fascia, which sometimes gets dissected in order to make the way for either a sub – pectoral or full sub – muscular implant placement.
As for the lobes, there may be up to 20 of them in each breast, in addition, there is a collection of about 5 to 10 larger milk ducts, which bear the name collecting ducts, a place, where a surplus of milk gets emptied into awaiting removal by the nursing baby. There is also glandular tissue, which resides in the outer upper part of the breast and it usually feels like lumps or nodules of tissue. In case if some woman does not know about her breast anatomy, during self - examination she may consider these lumps to be a cyst or even a tumor. But as a rule it is simply a gland, though, in case if there is any doubt or concern, then it would be better to apply to the gynecologist or mammologist, a doctor, who specializes on the female breasts problems. It is also possible to feel some breast tenderness in this area, which usually occurs right before menstruation.
