The breast is a symbol of maternity for children, an association with beauty for men, and a pair of important sexual organs for women. Women's breasts play an important role in reproduction and sexual activities. In addition to the responsibility of nurturing the next generation, they also play an important role in male and female sexual activities. The breast is composed of about 15-20 lobes, surrounded by fat and fibrous tissue, and the ducts of each lobe open separately at the nipple.
