Why do some women have big breasts and some have small breasts?

Because people's physical fitness is different, some people have big breasts and some have flat chests. Genetic factors, female hormone factors and lifestyle all determine the size of the breasts. If the secretion of estrogen is high, the breasts will become larger and firmer under the stimulation of growth hormone; secondly, if the patient exercises regularly or massages the breasts regularly, it will also cause breast enlargement. Therefore, some people have big breasts and some have flat chests. Patients do not need to worry, they can achieve the effect of breast enhancement and breast beauty through acquired massage.

Some people have soft breasts, while others have hard breasts. This may be related to the following reasons: women's breasts are composed of fat and mammary gland tissue. If a woman's breast fat rate is higher, the breast will feel softer. Some women, due to long-term physical exercise, make their breast muscles stronger and feel harder. Before the menstrual period comes, some women's hormone secretion increases, and their breasts become relatively hard, which will gradually become loose after the menstrual period ends.

Middle-aged and elderly women may have soft breasts due to lack of collagen in their breasts or sagging breasts. Hard breasts may be caused by breast hyperplasia. This disease will cause lumps in the breasts, accompanied by pain, especially before menarche. The symptoms are more obvious. The hardness or softness of the chest may be related to other conditions. If the chest appears excessively hard or accompanied by pain, it is best to go to the hospital for further examination.

This is related to women's congenital genetic inheritance and acquired growth and development. The breasts are composed of human fat tissue, connective tissue, glandular ducts, and mammary gland tubes. If a woman's breast tissue is mostly composed of fat tissue, the main manifestation is that the breasts are soft, loose, and lack elasticity. If the glandular ducts account for the majority, it is a high-density breast, and the main manifestations are that the breast is plump, firm and visible, and it is soft and malleable to the touch. In our country, the vast majority of young women have high-density breasts. Middle-aged and elderly women usually have fatty breasts. Secondly, it is related to acquired diet and exercise. Women with malnutrition and obesity have soft breasts, while women who insist on exercising have firm breasts.
