If you are unfortunately diagnosed with cancer, it would be beneficial to consult an experienced specialist at an oncology hospital or oncology specialty before deciding on specific treatment measures. When you visit the hospital again, consult or transfer to another hospital for treatment, you should bring all the medical records from the original hospital, including: pathological diagnosis report and, if necessary, wax blocks for re-examination or additional molecular pathological markers of tumor tissues, imaging examination data (X-ray, CT, MRI, ECT, PET, ultrasound, etc.), treatment history (radiotherapy, chemotherapy protocol and cycle, surgery records, etc.), and Recent laboratory test results (blood routine, liver and kidney function, electrolytes, tumor markers), etc., for the reference of the receiving physician to judge the condition, which can avoid unnecessary repeated examinations, reduce medical costs, and save time at the same time.
