Estimating the second primary cancer risk due to proton therapy compared to hybrid IMRT for left sided breast cancer

Proton therapy has been proposed as a technique to improve the long-term quality of life of breast cancer patients. This is due to its ability to reduce the dose to healthy tissue compared to conventional X-ray therapy. The aim of this study was to investigate the risk of secondary carcinogenesis due to proton therapy compared to hybrid IMRT for breast treatments.In this study, the Pinnacle treatment planning system was used to simulate...
