Most Appropriate Radiation Therapy Techniques for The Breast Cancer Treatment: Dosimetric Analysis of Three Different Radiation Therapy Methods

Background: Radiation-induced cardiac events and pneumonitis are the major late radiotherapy side effects. Methods: We explored differences in dose distribution between 3D CRT, IMRT VMAT 125 women with unilateral breast cancer. The various to tumor OARs were studied for left right sided irradiation. Results: Upon using CRT breasts lymph nodes, we observed a significant increase ipsilateral lung. Having irradiated only breast, there was negligible Dmean difference adjacent lung three methods, likewise myocardium cases. For right-sided cases showed lowest doses myocardium. Conclusion: Radiation oncologists should consider if conditions do not allow devising plans different methods. This turn will reduce cardio pneumotoxicity of cancer treatment. In treatment cancer, physicians focus on CRT.
