Skin Reaction in Radiation Therapy for Breast Cancer
Introduction The first medical intervention for many breast cancer patients is breast conserving surgery (BCS) and/or modified radical mastectomy (MRM). Most of these patients undergo radiation therapy, following surgery. The most common side-effect of breast radiotherapy is skin damage. In the present study, the severity of acute skin changes and the underlying causes were investigated in pati...
متن کاملOptimization of tangential fields arrangement in the breast cancer 3D conformal radiation therapy
Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
متن کاملEstimation of the thyroid secondary cancer risk on the patient of standard breast external beam radiotherapy
Introduction: The purpose of this study was to estimate the secondary cancer risk of thyroid for standard radiotherapy methods which are commonly used for breast cancer patients. Materials and Methods: Sixty-four breast cancer patients (their age range was around 50 years old) who referred to Seyed- Al- Shohada hospital (Isfahan, Iran) were included in this ...
متن کاملComparison of Electron and X-Ray Beams for Tumor Bed Boost Irradiation in Breast-Conserving Treatment
PURPOSE This study aimed to compare the dosimetric profiles of electron beams (EB) and X-ray beams (XB) for boosting irradiation in breast cancer patients who underwent breast-conserving surgery and postoperative radiotherapy. METHODS For 131 breast cancer patients who underwent breast-conserving surgery, we compared plans for EB and XB boost irradiation after whole-breast irradiation. The or...
متن کاملoptimizing of the tangential technique and supraclavicular fields in 3 dimensional conformal radiation therapy for breast cancer
radiotherapy plays an essential role in the management of breast cancer. three-dimensional conformal radiation therapy (3d-crt) is applied based on 3d image information of anatomy of patients. in three-dimensional conformal radiation therapy (3d-crt) for breast cancer one of the common techniques is tangential technique. in this project, various parameters of tangential and supraclavicular fiel...
