The breast is a deformed glandular tissue. Natural breast consists of three main types of tissues, including fibrosis, glandular and fat. Before menopause, fibrosis and glandular tissues are a combination of constipation, glands, and connective tissues surrounded by a thin layer of fat while after menopause, fibrous and glandular tissues are dwindled and fat tissues are developed. Each of the breasts has 15 to 20 tuberculosis lobes, which are linked by fibrous connective tissue. Within each lobe are smaller structures, called lobules (where milk is produced). Each lobe is the content of the lobes (clusters of secreted cells called areola, which are opened to the milk-transferred tubes). A duct drains each lobe. Two or three ducts of the milk are connected to each other, altered into the lacrimal sinus and eventually into the secreting milk duct and are opened at the nipple's cripts. The natural diameter of the duct is 2-1 mm and reaches 4 mm in the sinus position.
