To better understand breast fat necrosis, it helps to understand the anatomy of the breast.

Breasts are made of fat and milk glands. Small passageways, called ducts, deliver milk from the glands, to the nipple. Lymphatic tissue provides a passageway for cell waste to drain from the breast.

Examples of breast anatomy:

• Breast milk glands
• Breast lymphatic tissues
• Breast surface anatomy
• Breast external and internal anatomy
