Some female friends will find that their breasts are particularly large, which is very different from the breast size of their peers. This will make them feel very embarrassed, and even feel a little lacking in confidence. However, few female friends will go to the hospital for a detailed examination due to the problem of large breasts. In fact, some large breasts are caused by certain breast diseases, rather than normal physiological development. What's the use of having big breasts on women? The first stage (1 to 9 years old): before puberty, breasts have not yet developed. The second stage (10-11 years old): In the early stage of breast development, the breast bud under the nipple begins to grow and appears as a distinct dome-shaped bulge. Stage 3 (12-13 years old): The breasts become round and shaped like adults, but are still small. Stage 4 (14-15 years old): The breasts enlarge rapidly, and the nipples and areola protrude forward, shaped like small balls. If you are still the same as when you were 13, you need to find out the reason. Stage 5 (16-18 years old): Normal adult breasts are formed, and the small balls of the nipple and areola merge into the round shape of the breast. Breast development The time when women's breasts begin to develop varies depending on factors such as region and race. For most women, breast development begins between the ages of 8 and 13, and fully matures between the ages of 14 and 18. Breast development usually starts from the left side, and it takes about 3-5 years from the beginning of development to full maturity. Symptoms of abnormal breast development 1. Multiple breasts and multiple nipples If the mammary rudiments do not degenerate or degenerate incompletely during the embryonic period, multiple nipples or multiple breasts will occur. Most of them occur on the baseline of breast formation, which is the line from the armpit to the groin. 2. Nipple Abnormalities An abnormality of the nipple refers to an abnormality in its size, shape, or position. A normal nipple is cylindrical and protrudes about 2 cm above the surface of the breast skin. Abnormal nipple position is common. According to the relationship between the nipple and the breast skin, it can be divided into flat nipple, inverted nipple and inverted nipple. 3. Breast hypertrophy One of the abnormalities of female breast development is breast hypertrophy. Macromastia mostly occurs during adolescence and pregnancy. The cause is still unclear, but it may be due to excessive sensitivity of breast tissue to estrogen. 4. Low breast development Small breasts or missing one or both breasts. The absence of both breast and nipple is called complete breast agenesis. People who have only nipples but no breasts are called partial breast loss. |
