The so-called individualized treatment focuses on each individual patient, because different people suffer from different characteristics of tumors, and traditional consistent treatment (such as surgery, chemotherapy, radiotherapy, etc.) may have different effects on different patients. The research of modern medicine is to obtain the maximum therapeutic effect through individualized research. For example, in chemotherapy, our hospital researches the therapeutic response of tumor cells to different drugs, so that patients can get the most appropriate treatment and get the maximum therapeutic benefit with the least possible economic expenditure.
