Learning Objectives: The goals of this educational exhibit are: To review the lymphatic drainage of the breast, emphasizing anatomy and physiology. To illustrate, compare and contrast the imaging techniques which can evaluate nodal disease in breast cancer patients. To demonstrate the complementary value of both anatomical and functional imaging.
Abstract Body: Breast cancer is the most common female cancer in the US and the second most common cause of death in women. Nodal spread of breast cancer doubles the patients risk of recurrence and distant metastasis. Determining the presence of nodal involvement provides crucial prognostic information and drives therapeutic decisions. Imaging, fine needle aspiration and sentinel lymph node biopsy have replaced surgical node dissection in many centers for staging breast cancer. Understanding the physiology and anatomy of the breast's lymphatic drainage is crucial for interpreting physicians. Multiple imaging techniques can play an important role in the nodal staging of breast cancer patients. The detection of N2 and N3 nodal metastasis by imaging is an significant and adverse indicator for breast cancer patients.
