Milk ducts in breast anatomy. Each breast has 15 to 20 sections or lobes that surround the nipple in a radial manner like spokes on a wheel. The milk making glands are divided into segments and the narrow tubes or ducts carry the milk from each segment to the nipple. It is the most common form of breast cancer.

For one breasts are not made of muscle but tissue glands and ducts. Lobular carcinoma refers to cancer in the lobules.

A healthy female breast is made up of 1220 sections called lobes. At the end of each lobule are tiny bulbs that produce milk. When milk is not removed from the breast a protein called feedback inhibitor of lactation fil is produced.

Nestled within a hefty dose of fat breast tissue contains a series of cells responsible for producing milk when the persons hormones signal for it to get ready to feed a newborn. Small tubes ducts conduct the milk to a reservoir that lies just beneath your nipple. Breast anatomy each breast contains 15 to 20 lobes of glandular tissue arranged like the petals of a daisy.

It is the most common form of breast cancer. This plug helps prevent bacteria from entering the duct. Each of these lobes is made up of many smaller lobules the gland that produces milk in nursing women.

However the lobules arent actually arranged in such a symmetrical formation. These lobules connect to the nipple via ducts so that milk can pass through. The neatly arranged petals in the illustration are lobules glands that produce milk.

Pressure on the ducts and tissue can prevent milk from flowing freely and this can lead to blockages and in turn to engorgement and then a reduction in milk supply. When a woman is not lactating milk ducts are blocked by a plug of keratin the same material that makes up hair nails and the outer layer of skin. Its contraction is responsible for the ejection of secretion in the milk sinuses and for the telotism of the papilla mimicking an erection.
