Breast cancer remains a leading cause of cancer-related morbidity and mortality among women globally. The advent of advanced radiotherapy techniques, particularly intensity-modulated radiation therapy (IMRT), has transformed breast cancer management by allowing for precise targeting of tumor tissues while minimizing exposure to surrounding healthy tissues. This presentation's ideas are generalizable to any system for treatment planning. But the writers have tweaked the Varian systems utilised by their respective schools in specific ways. To minimise the risks of skin toxicity and residual oedema after breath control, respiration motion, or ageing, this document covers the specifics of using linear accelerators mounted on C-arms or O-rings, as well as strategies for dealing with resource constraints, target cropping, and skin flash. In this work, we offer a decision tree, go over some real-world examples of contoured and non-contoured target volumes, explain how to choose between fixed beam intensity modulation and volumetric modulated arc therapy, and describe the technical aspects of the implementation (such as tangential IMRT, butterfly IMRT, or VMAT). We provide and synthesise practical suggestions for breast planning using a decision tree and technical summaries. This research paper provides a detailed exploration of the utilization of IMRT in breast cancer treatment, discussing its clinical benefits, methodologies, and outcomes. Through an in-depth review of current techniques and clinical data, this paper offers recommendations for optimizing IMRT protocols to improve patient outcomes, aiming to reduce toxicity and enhance the quality of life for breast cancer patients.
