Breast Lymphatics
There are three groups of lymph nodes that receive lymph from breast tissue – the axillary nodes (75%), parasternal nodes (20%) and posterior intercostal nodes (5%). The skin of the breast also receives lymphatic drainage: Skin – drains to the axillary, inferior deep cervical and infraclavicular nodes. Nipple and areola – drains to the subareolar lymphatic plexus.
