Breast Anatomy        

The female breasts are made up of lobules, ducts, and stroma.  Lobules are glands which produce milk.  Ducts are tubes which carry milk from the lobules to the nipple.  Stroma are connective and fatty tissue which make up the breast and encompass the ducts, lobules, blood vessels, and lymphatic vessels. 

The lymph system is the way which breast cancer is spread to the rest of your body.  It consists of the following parts:

  • Lymph nodes- small clusters of immune system cells which help fight infection
  • Lymphatic vessels- tubes which carry clear fluid called lymph away from the breast
  • Lymph- fluid which contains tissue, waste products, and immune cells

In the breast, most lymphatic vessels are connected to lymph nodes under the arm, called axillary nodes.  Other lymphatic vessels connect to lymph nodes in the chest, called internal mammary nodes.  There are also lymphatic vessels which connect above or below the collarbone, supraclavicular or infraclavicular nodes.
