Even in the middle stage of kidney cancer, clinical cure can be achieved, but not complete cure. The so-called clinical cure means removing the tumor in the patient’s body so that there is no tumor in the patient’s body, but there are still metastasis and recurrence in the long term. Before metastasis and recurrence, patients can eat and drink or do physical labor as normal people do, which will not have obvious effects, but they need to go to the hospital for lifelong follow-up, which should include kidney function test and urological imaging test, such as CT or ultrasound of both kidneys, so as to find out whether there is any metastasis at an early stage, and then carry out the relevant treatments as early as possible. In the middle stage of kidney cancer, except for surgical treatment to remove the tumor, it is also necessary to remove the kidney with tumor, and after surgery, it is necessary to decide whether to take oral targeted drugs or carry out some immunobiological treatments according to the results of the examination, so as to greatly prolong the median survival rate of the patients and improve the quality of life of the patients through the targeted drugs and their immunobiological treatments.
