Common symptoms of kidney cancer include:
- Blood in your urine (which may make urine look rusty or darker red)
- Pain in your side that doesn’t go away
- A lump or mass in your side or abdomen
- Weight loss for no known reason
- Feeling very tired
These symptoms may be caused by kidney cancer or by other health problems, such as an infection or a kidney cyst. People with these symptoms should tell their doctor so that any problem can be diagnosed and treated as early as possible.
