In the translation of medical documents, ignoring professional terms is very likely to affect the safety of diagnosis and treatment. Here are some reasons: 1. **Accuracy**: Medical documents contain a large number of professional terms, which usually have specific meanings and usages. If these terms are ignored or mistranslated during the translation process, it may lead to misunderstandings in the patient's medical records, medication instructions or treatment plans, thereby affecting diagnosis and treatment decisions. 2. **Communication**: Effective communication between doctors and patients is essential to ensure patient safety. If professional terms are not accurately translated, patients may not understand their condition and treatment plans, which may lead to incorrect self-management or refusal of appropriate treatment. 3. **Legal liability**: Medical professionals need to rely on accurate documents during the treatment process. If improper translation causes medical staff to make wrong judgments, legal liability may result. 4. **Drug safety**: Incorrect translation of professional terms such as drug names, dosages and instructions for use may cause patients to take the wrong drugs or dosages, causing serious health risks. 5. **International medical care**: In cross-border medical exchanges, accurate translation of professional terms is particularly important, which is related to the effective connection and information transmission between different medical systems. Therefore, when translating medical documents, it is necessary to pay attention to the accuracy of professional terms to ensure patient safety and treatment effectiveness. Hiring professional translators with relevant medical backgrounds can effectively reduce such risks.
