ON THIS PAGE: You will find a basic drawing of the main body parts affected by breast cancer. Use the menu to see other pages.
The image is a drawing of a person’s breasts. The breast is made up of different types of tissue, which sit on top of the pectoralis major muscle over the ribcage. Within the fatty tissue of the breast is a network of lobes, made up of tiny, tube-like structures called lobules that contain milk glands. Lactiferous ducts connects the lobes, glands, and lobules to carry milk to the nipple, located in the middle of the areola, the darker area that surrounds the nipple. Lymph vessels also run through the breast, and connect to axillary lymph nodes, tiny, bean-shaped organs that are found in groupings in various parts of the body, including the armpits.
