Breast

Each breast has six to nine overlapping sections, called lobes. Within each lobe are many smaller lobules, which end in dozens of tiny bulbs that can produce milk. The lobes, lobules and bulbs are all linked by thin tubes called ducts. These ducts lead to the nipple in the center of a dark area of skin called the areola. Fat fills the spaces around the lobules and ducts. There are no muscles in the breast, but muscles lie under each breast and cover the ribs. Each breast also contains blood vessels and vessels that carry colorless fluid called lymph. The lymph vessels lead to small bean-shaped structures called lymph nodes. Clusters of lymph nodes are found in the axilla under the arm , above the collarbone and in the chest. Lymph nodes are also found in many other parts of the body.

The breasts are divided by an invisible line running up and down and right to left through the nipple. Each of these 4 regions is called a quadrant. Most breast cancers develop in the upper outer quadrant of the breast, closest to the armpit. This is because this area has a lot of glandular tissue. Each breast lies over a large muscle called the pectoralis major muscle on the chest. The breast covers a fairly large area. It goes from just below the collarbone called the clavicle to the armpit called the axilla and across to the breastbone called the sternum. Breasts start to grow during puberty, which usually takes place between 10 and 12 years of age. At this time, the breasts respond to hormonal changes in the body. These changes include higher estrogen and progesterone levels in the body.
