The breast or breast consists of fat, connective and glandular tissue. Each breast is between 10 and 20 sections known as lobes, which in turn are divided into smaller sections, the lobules. The lobules contain milk-producing glands during lactation. Through the milk ducts to the nipple arrives.
Lobules and ducts are in the stroma, adipose tissue in which the blood and lymph vessels, lymph nodes are also located. These nodes are responsible for protection against bacteria, tumor cells and other harmful substances.
Breast cancer occurs when cells of the glandular epithelium reproduce uncontrollably and very quickly. These cancer cells can travel through the blood and lymphatic vessels and reach other parts of the body, where they can adhere to the organs and form metastases.
