Have you ever wondered what your breasts consist of?

Breasts are made of lobes and ducts. There are 15-20 lobes in each breast, which have many smaller sections called lobules. The lobules end in dozens of tiny bulbs that can make milk. Lobules, and bulbs are linked by thin tubes called ducts.

Both breast contain blood vessels and lymph vessels. Lymph vessels carry a watery substance called lymph. Lymph nodes are small, bean-shaped structures that help to filter lymph and store white blood cells. These white blood cells help fight infections and diseases. Lymph vessels carry lymph between lymph nodes. 

Groups of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone and in the chest.
