| Question | Answer |
| The base of female breast extends | Vertically from 2~6 ribs |
| Extends Transversely from | Sternum to Axilla |
| Extension known as | Axillary Process |
| Female breast consists of | Glandular Tissue Adipose Tissue Connective Tissue Septa |
| Areola | Excretory ducts of the glandular tissue. |
| Areola glands | Mark the opening of the Sebaceous glands |
| Lactiferous ducts | Opening of the nipples via Lactiferous Sinus |
| Layer of deep connective tissue | Retromammary Space |
| Retromammary Space | Separates the breast from the underlying deep fascia and provides the breast some degree of movement. BREAST CANCER THAT ATTACKS HERE IS ADVANCED CARCNINOMA!!! |
| Suspensory Ligaments | Connective tissue that attaches the mammary glands to the overlying dermis |
| Veins draining from the Breast ultimately drain into | axillary, internal thoracic and Intercostal Veins. |
| Breast tumors typically | Spread through the ducts of the lymphatic drainage of the breast*** |
| 75% OF LYMPHATIC VESSELS DRAIN into | Axillary nodes |
| Extra lymph that doesn't get drained works its way back through the | Axilla nodes |
| Most of the remaining lymph particularly from the medial portion of the breast flows into the | Parasternal Lymph nodes.. |
| Tumors that spread across lymph nodes and across breasts | Contralatteral Tumors |
| 5 Groups of Lymph nodes | 1.Pectoral (anterior nodes) 2. Humeral (Lateral Nodes) 3. Subscapular (Posterior Nodes) 4. Central nodes 5. Apical Nodes |
| Pectoral (anterior nodes) | Receives Majority of lymph nodes from the breast tissue |
| Humeral Nodes | Receives Majority of lymph nodes from the upper limb |
| Subcleavean Nodes | Receive lymph from back and shoulder |
| Central Nodes | Embedded with the axillary fat |
| Apical Nodes | Receive lymph from all other axillary groups |
| Lymph from the apical nodes flow into the | right lymphatic duct (right) or Thoracic Duct (Left) |
| Peau d Orange | Tumor growth blocking small superficial lymphatic channels resulting in eedema and prominent hypertrophy |
| Mastectomy | Removal of breast |
| During Mastectomy | Log thoracic duct may be damaged due to its medial position within the axilla resulting in a winged scapula |
