Is this kind of chest normal? Do you have a chart?

Because of race, heredity, age, breastfeeding and other factors, the shape of breasts will be very different. The breasts of adult women in China are generally hemispherical or conical, with both sides basically symmetrical, and droop to a certain extent or slightly flat after breastfeeding. Older women's breasts tend to shrink, droop and be soft. The center of the breast is the nipple. Normal nipple is cylindrical or conical, with symmetrical sides and pink or brown surface. The diameter of nipple is about 0.8 ~ 65,438+0.5 cm, and there are many dents on it, which is the opening of milk delivery pipe. The annular area with deep pigmentation around the nipple is areola. The areola is about 3 ~ 4 cm in diameter, with different colors, rose red in adolescence and dark brown during pregnancy and lactation. The skin of the breast is thicker around the gland and thinner at the nipple and areola. Sometimes superficial subcutaneous veins can be seen through the skin.

The breast is located in front of the pectoralis major muscle on both sides of the chest, and its position is also related to age, body shape and breast development. Adult women's breasts are generally located between the second and sixth ribs of the chest, with the inner edge close to the sternum, the outer edge reaching the axillary front, and the axillary midline when the breasts are enlarged. The extremely long and narrow part outside the breast forms the axillary tail of the breast and extends to the armpit. Young women's nipples are generally located at the level of the fourth rib or the fifth rib,1cm; Outside the clavicle midline; The nipple of middle-aged women is located at the sixth intercostal level, outside the clavicle midline 1 ~ 2 cm.

Because there are great individual differences in the shape and position of breasts, the development of female breasts is also affected by age and various physiological periods. Therefore, it is necessary to avoid treating the shape and position of the breast that belongs to the normal range as morbid, thus generating unnecessary ideological burden.
