Breast Anatomy
Most of the breast is made up of a collection of fat cells which explains the fluctuation in size during your life. There are also areas called lobes (1) lobules (2) and lactiferous ducts (3). A breast is made up of 15 to 20 sections called lobes that surround the nipple (4). Each of these lobes is made up of many lobules, small round bags that produce milk in breastfeeding women. The lobes are connected by lactiferous ducts to transport milk to the nipple, which is in the center of a dark area of the skin called the areola (5). The areola contains small glands that lubricate the nipple during breastfeeding.

Each breast also has a network of ligaments, connective tissue, nerves, lymphatic vessels, lymph nodes (6) and blood vessels. The lymphatic system, which is part of the immune system, is a network of lymphatic vessels and lymph nodes circulating throughout the body. Lymph nodes are small kidney-shaped structures located near the lymphatic vessels. They act as filters by removing abnormal cells from healthy tissue.

Each breast rests on a large muscle called the pectoral muscle (7), with the ribs and the rib cage (8) below. There aren’t any muscles dedicated to supporting the chest; therefore, the relaxation that occurs as you get older is natural.
Breast Development
Breast Development
From childhood to puberty and until menopause breasts change, both in shape and in size.
Young girls have a small amount of immature breast tissue.
During puberty, hormones produced by the ovaries and the pituitary gland (part of the brain that controls growth and other glands in the body) cause breasts to grow. This causes the milk ducts to stretch and branch out.
There are 15 to 20 lobes in each breast. Each lobe has 20-40 lobules. Although the breast is mature after puberty, the breast tissue remains inactive until pregnancy.
Pregnancy and breastfeeding
During pregnancy, the lobules grow and begin to produce milk. The milk is then released into the ducts so that a mother can breastfeed her baby.

After menopause (when the ovaries stop producing hormones and a woman stops having her period), the number of lobules decreases and the remaining ones shrink. The loss of breast tissue during menopause means that breast density also decreases.
What about boys?
Boys and girls start their lives with similar breast tissue. However, men do not have the same breast growth and development as women.

Our breast health progam promotes the role of lifestyle changes in reducing the risk of breat cancer for people of all genders and all ages.

“I Love My Boobs” is more than a slogan.
It’s an attitude and it’s a commitment.
