The typical three major symptoms of kidney cancer are hematuria, pain, and a mass. If these three symptoms appear, it generally indicates that the condition has reached an advanced stage, at which point the patient may have missed the optimal timing for treatment. Surgery at this stage may also be challenging to perform completely. Therefore, early detection and treatment are essential. The five-year survival rate after kidney cancer surgery is as high as 97% for many people. Thus, overall, the prognosis for kidney cancer is relatively good. However, the best treatment approach remains surgery, including nephron-sparing surgery and radical nephrectomy, depending on the size of the tumor. Generally, for tumors smaller than four centimeters, nephron-sparing treatment can be adopted.
