Whether the tumor is serious and how to treat it should be combined with the nature, type and pathological staging of the tumor for specific analysis, which can’t be briefly summarized as follows. 1. Nature: generally malignant tumors are more serious and need surgery or drug treatment, such as renal cell carcinoma, etc. Benign tumors are generally not serious and can be dynamically observed and surgically treated when necessary, such as vascular smooth muscle tumor, etc. 2. Types: renal tumors are mostly malignant, generally divided into renal cell carcinoma, nephroblastoma and upper urinary tract tumors, all three types are malignant tumors of more serious, the specific treatment needs to be combined with the pathology and clinical staging to decide the treatment plan, such as surgery in early stage, and radiotherapy in late stage. 3. Pathological staging: generally the prognosis of tumors with early pathological staging and low degree of malignancy is better, and surgical treatment is usually adopted to remove the tumor completely, and some of them can be cured by surgery; if the pathological staging is late, the prognosis of tumors with high degree of malignancy is generally worse, and it is often necessary to adopt various ways of combined treatment, such as radiotherapy, chemotherapy, palliative surgery, and so on.
