Abstract:
Radiotherapy plays an important role in the treatment of breast cancer. This technique is used of photon and electron beams produced by a linear accelerator to treat breast cancer. The aim of this study was to evaluate the effect of radiotherapy in the treatment of breast cancer is the mostcommon techniques. Material and methodes: The techniques are practical and have been implemented using phantom trunk and EDRII films. For these practical Techniques, films were placed between the slice of the phantom and were irradiated under selected conditions and after irradiation, the irradiated films in various techniques have been appeared under the same conditions with the processor radiology AR 200XT. Result: Studies show that as a result of using adjacent fields in radiotherapy techniques, Parts of the target volume received dose twice or more than the prescribed dose but by the photon dose technique, rate of received dose is more uniform and closer to the prescribed dose.
