Different Types of Brachytherapy at the Internal Mammary Nodes in Breast Cancer Patients

Abstract

Purpose: It’s well known that mediastinum, lungs, heart, spinal cord are the unwishful targets in distant radiation therapy at the parasternal zone in breast cancer patients. Different treatment-related morbidity has been observed. That was the reason for the modern radiation therapy application at this zone. It has been shown that internal mammary artery is the optimal natural pathway for the radiation sources which leads to symmetrical irradiation of internal mammary lymph nodes.
