After the diagnosis of malignancy, patients and family members usually go through a series of processes such as doubt, denial, collapse, recovery, acceptance, cooperation with treatment, and rebuilding confidence. Some of them will go through the whole process, while some have several of these steps. However, some patients and family members choose the wrong approach of “seeking medical help in a hurry” after receiving the diagnosis. First of all, although malignant tumor is a serious disease that threatens everyone’s health, most of them are chronic diseases in terms of development. From the time it first starts to become malignant to the time it is detected and diagnosed, there is already a stage, and it will not become malignant quickly because it is diagnosed (such as puncture examination and other operations). Therefore, it is not necessary to necessarily treat on within a few days after the diagnosis of malignant tumor. Instead, the necessary related examinations such as laboratory tests, CT/MRI, ultrasound and endoscopy should be completed under the guidance of a professional doctor. The purpose of the examination is to give the doctor a comprehensive understanding of the extent of the lesion and to make a complete plan for the patient’s treatment. The second misconception is that not all malignant tumors must be surgically removed. Some malignant tumors, such as nasopharyngeal carcinoma, lymphoma, and tumors of the hematological system, require chemotherapy and radiotherapy, and the purpose of surgery is only to obtain pathological results. There are also some advanced lesions, such as advanced lung cancer, for which surgery is not preferred if brain metastases are also found. Of course, for most malignant tumors, surgery is the most important modality for radical treatment, that is, to obtain curative results. However, since most of the tumors are already locally advanced at the time of detection, a single surgery cannot get the best result, and should be combined with radiotherapy and chemotherapy, which we call multidisciplinary comprehensive treatment. It is like marching to war, some small battles are solved by infantry (surgery); but some big battles need the synergy of army, air force (radiotherapy and other departments), etc. to defeat the enemy! If improper or inadequate treatment is done in a hurry, it is sometimes difficult to make up or save the healing! This is most unfortunate! Therefore, after the diagnosis of the disease and before the implementation of treatment, it is necessary to discuss and discuss in a multidisciplinary manner and implement the treatment in a planned manner in order to achieve the best results!
