The objective of this research was to analyze the risks in 3D conformational teletherapy for breast cancer treatment by applying a risk analysis methodology. Treatment processes for breast cancer with 3D conformational teletherapy, image-guided radiotherapy and boost were included in the research. The stages that presented the highest risk percentages were the printing of the technical file (20%), other days of treatment (10.4%) and electron boost (13.3%). Failure modes with Severity parameter scored equal to or greater than 7 resulted in the following percentages: data sheet printing (80%), first day of treatment (79.9%), electron boost (81.8%), export planning (58.8%), other days of treatment (70.9%), boost planning (69%) and photon boost (75.8%). The stages that presented the highest percentage of failure modes with Severity parameter scored 10 were the export of the planning (58.8%), printing of the technical file (80%), first day of treatment (65.9%), other days of treatment (56.7%), photon boost (70.5%) and electron boost (75.1%). The causes of the most significant potential failure modes stem from human failures.
