The breasts are the normal thymic tissue of a woman that serves for cosmetic and lactation purposes, feeding the next generation after childbirth. Normal breasts are located on both sides of the chest. The shape is hemispherical in adult women. Double breasts are congenital. Like mammals, humans have many pairs of primitive breasts, but during primate development, many of the attached double breasts degenerate, leaving a pair of normal breasts for lactation. The secondary breast is a small piece of fat that did not fully form during the degenerative process in our ancestors. Most appear in front of the armpits and a few around the belly button. It is recommended to eat less spicy and irritating, greasy food. Eat more light and high-fiber foods and supplement more vitamins and proteins. Good living habits, do not stay up late, go to bed early and get up early, and relax and exercise appropriately.
