Kidney cancer is a common tumor in urological surgery, and a typical symptom in patients with kidney cancer is the appearance of hematuria. The characteristic of this hematuria is that it is painless visible hematuria throughout the course. Initially, the severity of the hematuria is relatively mild, occurring intermittently. However, over time, the hematuria gradually worsens, and the intervals shorten, even leading to significant bleeding. Another symptom of kidney cancer is back pain, which is caused by the increased size of the tumor pulling on the kidney, causing pain. When the tumor presses, it can also lead to severe back pain. A mass is another common symptom of kidney cancer; when a mass is felt on one side of the upper abdomen or back and moves up and down with respiration, it is generally indicative of the late stages of kidney cancer. Therefore, the typical symptoms of kidney cancer are hematuria, pain, and a mass.
