What Are Renal / Kidney Masses?
Renal masses are abnormal growths located within the kidney that may be benign or cancerous in nature. Located around the middle of the back and under the ribcage, kidneys are organs that filter blood by removing water and waste byproducts from the body. When a mass (also referred to as a lesion or tumor) is present, it may impair normal kidney function or even lead to other health concerns. Urologists are often involved in the management of care for benign and cancerous renal (kidney) tumors.

What Are the Causes of Renal / Kidney Masses?
Renal masses have no one medically defined cause. However, risk factors for kidney masses or tumors may include:
- Genetics or genetic disorders, such as polycystic kidney disease or Von Hippel-Lindau syndrome
- Obesity or consuming an unhealthy diet
- Exposure to specific chemicals
- High blood pressure
- Being on kidney dialysis
Additionally, research indicates that repeated nonsteroidal anti-inflammatory drug (NSAID) use may be a risk factor, but more studies are needed to confirm this link.
What Are the Symptoms & Risk Factors for Renal Masses?
It's common for patients with kidney tumors or cancer to experience no symptoms, especially when masses are smaller in size. In fact, kidney tumors are often discovered by accident, for instance when a physician is evaluating another health issue through imaging or other diagnostic screenings. In some cases, however, renal masses may have signs and symptoms that include:
- Blood in urine
- Lower-to-middle back pain
- Bulging of the lower-to-middle back
- Weight loss or loss of appetite
- Low energy and fatigue
Though the precise cause of kidney tumors and cancer is not clear, there are certain factors that may increase a person’s risk for these types of conditions, such as:
- Alcohol use
- Poor diet
- Kidney dialysis
- Certain medications
- Advanced renal disease
- Exposure to certain chemicals
- History of high blood pressure
