Figure 1. Breast tissue may also be called glandular tissue. The female breast Changes during childhood and the teen years Throughout childhood, girls have a small patch of immature breast tissue. Cooper's ligaments are found under the skin of the breast, through and around the breast tissue. Mammary alveoli are the site of milk production and storage in the mammary glandular tissue.
Mammary alveoli cluster into groups called mammary lobes. Each breast has about 12 to 20 sections called lobes, each of which is composed of many smaller structures known as lobules. Lobules sometimes referred to as your mammary glands are a few millimetres long and hollow.
Lobules produce milk and store it. Wonder how milks get from your lobules to the nipples. There are approximately 15 to 20 milk ducts located in each breast. Veins are a critical part of our bodily system, transporting blood to the heart. As you likely know, veins are more visible in certain parts of the body, especially the arms and legs. For some women, they are more visible in the breasts.
Lymphatic capillaries arise from the breast lobules. The lymph vessels lead to small bean-shaped organs called lymph nodes. These lymph nodes are found in clusters under the arm, above the collarbone, and in the chest. That ring of pigmented skin around your nipples is called the areola. Like breasts themselves, the areola can differ in shape, size and colour for different women. It is sometimes helped by non-steroidal anti-inflammatory medicines taken in tablet form or rubbed on to the skin.
Breast cancer usually causes a painless lump but this is not a golden rule. If you have any type of breast pain, it's best to get it checked out by your doctor.

A central duct opens into the nipple from each lobe. A band of muscle surrounds each gland. Eventually, a sucking baby extracts the milk by pressing and pumping it out from these pools through the nipple. The spaces around the lobes and ducts are filled with fatty tissue and ligaments.
The size of a non-lactating breast is largely determined by the amount of fat it contains. Underneath the breasts there is fibrous tissue and muscle.
The pectoral muscle passes underneath the breast and connects the chest and the arm. Lying further below the pectoral muscle are the ribs which are connected by intercostal muscles , which raise and lower the rib cage when breathing in and out.
