Summary
Brief summary (as posted)
The study purpose is to evaluate whether or not clinical characteristics of women with breast cancer can predict which position for radiation treatment, prone or supine, will be associated with a dosimetry gain. Dosimetry gain in this study means the lowest radiation dose to non-target organs (heart, lungs, contralateral breast), while giving the prescribed dose to tumor bed and ipsilateral breast.
