在接受放射治疗之前通知患者是一项基本的伦理要求。作为自主权的可能性条件，信息使人们能够对自己的健康做出决策，而这也是法国法律要求的。这些信息包括尤其是由放射治疗造成的潜在风险。因此，有必要思考风险是什么，如何定义和评估风险，以便最终将其传达出去。告知人们的实践涉及到许多伦理问题，涉及到信息的内容本身、传递信息的形式，甚至是导致卫生专业人员表达（或不表达）风险的意图。信息的传递还涉及到如何与患者建立起信任关系，以及如何将他们自己对这些治疗的理解纳入其中。在权威主义或者防御性医学的风险中，这一实践正成为我们专业实践的核心。版权所有 © 2023 Elsevier Masson SAS 发布。

Informing patients before receiving radiation therapy is a fundamental ethical imperative. As a condition of the possibility of autonomy, information allows people to make health decisions concerning themselves, which is required by French law. This information includes in particular the potential risks due to radiation therapy. It is therefore necessary to think about what risk is, and how to define and assess it, in order to finally communicate it. The practice of informing people involves many ethical issues relating to the very content of the information, the form in which it is transmitted or even the intention that leads the health professional to say (or not to say) the risk. The transmission of information also questions the way to build a relationship of trust with the patients and how to integrate their own representations about these treatments. Between the risks of paternalism or even defensive medicine, this practice is at the heart of our professional practice.Copyright © 2023. Published by Elsevier Masson SAS.
