Your kidneys work silently every day, filtering blood, balancing fluids, and removing waste from your body. Because they’re tucked deep inside, problems often go unnoticed until they become serious. Kidney cancer is one such condition—its early signs are often subtle, but recognizing them in time can save lives.
Common Warning Signs of Kidney Cancer
1. Blood in the Urine (Hematuria) 
Even a small amount of blood in the urine is a red flag. It may appear pink, red, or cola-colored. Don’t ignore this—get it checked right away.
2. Lower Back or Side Pain 
Persistent pain on one side of the lower back or just below the ribs can signal kidney issues, including tumors.
3. Unexplained Weight Loss 
If you are losing weight without changing your diet or exercise routine, it could be linked to underlying illness.
