Yes, neglecting professional terminology in medical document translation may lead to misunderstanding. The medical field involves many complex terms and concepts, which often have very specific meanings. If these terms are not handled accurately during the translation process, the following problems may occur: 1. **Information Error**: Incorrect translation may lead to misleading information, which in turn affects medical decisions. 2. **Safety Risk**: Misunderstanding of medical conditions or treatment options may have serious consequences for the health and safety of patients. 3. **Legal and Ethical Issues**: Inaccurate medical translation may trigger legal liability or ethical issues, especially when it comes to patient informed consent. 4. **Loss of Professionalism**: Inaccurate translation may damage the professional image of medical service providers in the eyes of patients. Therefore, in medical document translation, it is crucial to ensure the accuracy of professional terminology, which usually requires relying on translators with a medical background or relevant expertise.
