What are kidney cancer symptoms and signs?
Common symptoms of kidney cancer include:
Blood in the urine (making the urine slightly rusty to deep red)
Pain in your side that doesn't go away
A lump or mass in the side or the 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.
