MEDICAL ANIMATION TRANSCRIPT: Breast cancer is the most common form of cancer in women today. Knowing more about your own breast anatomy can help you in early cancer detection and prevention. Your breasts are connected to small masses of tissue called lymph nodes by way of lymph vessels. The lymph nodes are responsible for collecting bacteria, cancer cells, and other unhealthy material. You have groups of these lymph nodes under your arms, above your collar bones, and behind your breast bone, as well as in other parts of your body. Each breast is made up of lobes, lobules, and ducts. The lobes consist of smaller lobules that contain groups of tiny milk-producing glands. When a breast is producing milk it passes through the ducts, into the nipple, where it exits the body. Breast cancer most commonly develops in the lobules, glands, and ducts of the breast. more
