Kidney cancer surgery such as nephrectomy, either radical surgery (total removal of kidney) or kidney preservation surgery (partial removal of cancerous lesion), will increase the load of kidney, but the kidney tissue left behind can usually maintain the healthy life of patients. Kidney is an organ of metabolism, removing part of the kidney tissue will increase the load of the remaining kidney tissue, some patients may have worse stamina and easy to be tired and weak after surgery. Post-operation kidney cancer patients should pay attention to maintain good living habits, healthy diet, regular exercise, and go to regular hospitals for timely checkup if any abnormality occurs. Besides, as kidney cancer is a malignant tumor, postoperative patients need to go to regular hospitals for regular review and timely screening of recurrence and metastasis. The earlier it is detected, the earlier it can be treated and prolong the survival time of patients.
