In the clinic, after radical surgery for early stage renal cancer, it is possible that it will not recur in the whole life. However, for malignant tumors, recurrence is its own nature, and it is impossible to define whether it will not recur at all. Therefore, once diagnosed with cancer, after radical surgery, patients should have regular checkups and avoid the factors that cause kidney cancer, including high-fat diet, smoking and drinking. Meanwhile, patients should keep a good mindset after radical surgery, consume some high-quality proteins in their daily life, and enhance exercise to maintain good immunity. If the immune system of human body is sound, it can effectively prevent the appearance of tumor. After early radical treatment of kidney cancer, the survival rate of human body is relatively high, so as long as regular review is conducted after the operation, usually there will not be more problems.
