Kidney cancer affects thousands of people each year, and the number of cases continues to rise. Because the disease may develop without obvious symptoms, recognizing potential warning signs can play an important role in getting an earlier diagnosis.
The disease is not always detected early

Because the kidneys are located deep inside the body, a tumor can grow for some time before causing noticeable symptoms.
Early diagnosis improves treatment outcomes

The chances of successful treatment are generally much higher when kidney cancer is found before it spreads beyond the kidney.
Blood in the urine can be a warning sign

Changes in the urine, including the presence of blood, are among the symptoms that should be evaluated by a healthcare professional.
