Breast Anatomy
As you learn about breast cancer, we will repeatedly reference the anatomy of the breast. Understanding the different parts and functions will help you better grasp the details of breast cancer.
Knowing your body helps you to:
- Make informed decisions.
- Have a better dialogue with your doctor.
- Be aware of anything unusual.
Adipose Tissue
The female breast is mostly made up of a collection of fat cells called adipose tissue. This tissue extends from the collarbone down to the underarm and across to the middle of the ribcage. As a woman ages, especially once she reaches menopause, the breast tissue contains more adipose (fatty) tissue.
Lobes, Lobules, And Milk Ducts
A healthy female breast is made up of 12–20 sections called lobes. Each of these lobes is made up of many smaller lobules, the gland that produces milk in nursing women. Both the lobes and lobules are connected by milk ducts, which act as stems or tubes to carry the milk to the nipple. These breast structures are generally where the cancer begins to form.
