Breasts are one of the indispensable organs of women, a symbol of female beauty, a pair of plump, round, upright breasts that many women dream of, no wonder some people say they are the wings of angels. Breast beauty is a part of human beauty, which forms a unified and harmonious whole with the human body. The normal development of the breast so that the female form is s-shaped curve, the size should also be with the total length of the body on the 0.618 split point, the size should also be proportional to the height of the body, fat and thin. The size and shape of the breast varies according to race, age, and human development, so it is difficult to find an ideal size of breast standard for everyone. However, for women with normal height and weight development, there is a general standard. Generally speaking, the ideal breast shape should be a full hemisphere or cone with a semicircular base and nipples at the top, protruding forward, outward and slightly upward. For Chinese women, what is the right size of breast? What is the right ratio of height to weight for Chinese women? Although there are some reference data, they are more often determined by the experience of physicians and individual aesthetic views, and it is difficult to determine the exact number. Some people have measured the breasts of young unmarried Chinese women and have come up with corresponding data. For example, for a woman of 1.60 meters in height, the standard breast volume should be 150 ml to 350 ml and the average breast height should be about 4.40 to 1.08 cm. However, it is difficult for women to measure their own breasts, and the ideal breasts should not only be the right size, beautiful in appearance and in proportion, but also free from any disease, with elastic skin, prominent nipples, normal contraction and erection function, even distribution of glands, symmetry on both sides, and no hyperplasia. Generally speaking, healthy and beautiful breasts also have their general standards. Breast health and beauty standards include two parts: the shape of the breast itself and the relationship between the breast and the body. The former refers to the elasticity of the breast, the fullness of the shape, the color off the degree, the local skin flatness, nipple status, etc.; the latter mainly refers to the breast position, size and shape relationship in line with certain aesthetic laws. Some people use the scoring method to quantify the standard of breast fitness, full score of 100 points (see Table 1). It must be stressed here that women do not have to deliberately pursue 100 points. Generally speaking, a score of 75 or more can be considered as healthy breasts.
