Breasts don't know the cold knowledge, do you really know? This article will introduce you to some knowledge about breasts.
First, what is the structure of the breasts?
The tissues that make up the breasts mainly include: mammary glands, connective tissue, fat, blood vessels, and nerves. Let's introduce them to you separately:
Breast – Whose role is to produce milk, there are about a dozen breast lobes that make up the mammary glands, and the mammary lobes have
It is also composed of mammary lobules, which are composed of acinar vesicles. On each breast lobe, there are separate milk ducts that transport the emulsion and eventually assemble on the nipple.
Connective tissue – Simply put, it is a bundle of fibers that connects other tissues within the breast and thus acts as a supporter. If a woman's connective tissue is well developed, she will have straight, elastic breasts.
Fat - mainly affects the size of the breast, usually women with large cups have more fat tissue in the body, on the contrary, women with smaller cups have relatively small body fat tissue. Of course, it is not excluded that women who have less fat tissue in the body but have undergone breast augmentation surgery.
Blood vessels – the blood transports nutrients to the breast and promotes the development of surrounding tissues.
Nerves – There are nerves everywhere in our body, and nerves exist because they are able to perceive stimuli from the outside world.
Let's look at the life of the breasts
When we were children, there was no difference in boys' and girls' breasts. However, when the age is 9-13 years old, the hormone levels in the girl's body change, and the breasts begin to develop gradually. Generally, when the development is 14-18 years old, it matures, and then the development stops.
When a girl has a chest development, it means that she has entered puberty, and the order of development is nipples, areolas, and finally breasts. Because the environment in each girl's body is different, the development of breasts is also different, and genetics, external factors, and living habits will affect it.
Even if the breasts are mature, they are not static, because during the menstrual period, especially in the week before menstruation, the hormone levels in the body change. At this time, the breasts will gradually enlarge, of course, this is not permanent, and when menstruation comes, the breast size will return to normal.
After the fertilized egg implants, the woman also becomes pregnant, at which point the breasts may gradually become larger, mainly in preparation for breastfeeding after childbirth. After childbirth, prolactin is excreted from the body, milk begins to form, and the breasts quickly enlarge.
As we continue to grow in age, about to 45-55 years of age into menopause, hormone levels in the body gradually decrease as some organ functions begin to decline. With low estrogen levels, the breasts may gradually shrink and become smaller. At this time, the breasts will also sag, women do not feel inferior, this is actually a normal physiological phenomenon, but different women, the time of arrival is different sooner or later.

If it occurs only occasionally, without special treatment, it generally does not endanger the health of the breast.
2. Anyone can have breast cancer
This disease is not only unique to women, but also may be suffered by men. As long as there is breast tissue, abnormal lesions may occur in the breast area, such as breast cysts, breast fibromas and other diseases. If the diseased tissue is not controlled, resulting in a continuous aggravation of the disease, there may be a malignant phenomenon of cell tissue, which may induce breast cancer. Although men's breasts are relatively small, it does not affect the incidence of breast cancer, but women have a higher chance of developing breast cancer than men. According to a medical study in the United States, the ratio of women to breast cancer is 1:8, while the chance of men developing breast cancer is 1:1000.
