In the translation of medical documents, ignoring professional terms is very likely to affect the safety of diagnosis and treatment. The following elaborates in detail from several main aspects： -**Diagnosis link** -**Inaccurate information transmission**: Professional terms in medical documents are the basis for accurately describing key information such as conditions, symptoms, and diagnostic results. If professional terms are ignored in translation and vague or wrong expressions are used, the information obtained by the doctor will be biased. -**Cause misdiagnosis**: Incorrect information may cause doctors to make wrong judgments and delay the diagnosis and treatment of the condition. For example, mistranslating “myocardial infarction” as “heart muscle injury”, this vague expression cannot accurately convey the severity and characteristics of the disease, and doctors may make inappropriate diagnoses and miss the best time for treatment. -**Treatment session** -**Wrong choice of treatment plan**: Accurate professional terminology is essential to develop the correct treatment plan. If the translation is wrong, the treatment plan formulated by the doctor based on the wrong information may not be able to target the patient's actual condition, and thus may not achieve the expected treatment effect, and may even cause harm to the patient. -**Medication errors**: Drug names, doses, and medication methods are all important contents in medical documents, and they all have strict professional terminology specifications. Ignoring the translation of professional terms may lead to medication errors, affect the patient's treatment effect, and even endanger life. -**Medical communication link** -**The patient's right to know is impaired**: The translation of medical documents is an important basis for patients to understand their own condition and treatment. Ignoring professional terminology will make it difficult for patients to understand the content of the document, unable to fully exercise the right to know, have doubts and anxiety about the treatment process, and affect treatment compliance. -**The collaboration of medical staff is hindered**: In a multi-disciplinary collaborative medical environment, accurate translation of medical documents can ensure the smooth communication of medical staff in different departments. If the translation of professional terms is wrong, it may lead to poor information transmission and collaboration problems, which in turn affect the overall treatment of patients.
