Kidney Cancer

Kidney cancer often develops without noticeable symptoms and may be discovered during imaging for another condition. Understanding the signs, risk factors, and available treatment options is an important step toward early detection and effective care.

What is Kidney Cancer?

Kidney cancer develops when abnormal cells in the kidney begin to grow uncontrollably, forming a tumor. The most common type in adults is renal cell carcinoma (RCC), which begins in the small tubes within the kidney that help filter waste from the blood.

Not all kidney tumors are cancerous. Some are benign, while others may grow or spread to surrounding tissues and other parts of the body. Kidney cancer often develops without noticeable symptoms in its early stages, which is why many tumors are discovered during imaging tests performed for unrelated medical concerns.

The size, location, and characteristics of a kidney tumor help determine the most appropriate treatment approach. When detected early, kidney cancer can often be treated successfully with surgery or other carefully selected treatment options.

Understanding Your Diagnosis

Diagnosing Kidney Cancer

Kidney cancer is often discovered when an abnormal mass is identified during imaging for another medical concern. Additional testing helps your provider evaluate the mass and determine the next steps.

Imaging Tests

CT scans, MRI, and ultrasound can help determine the size, location, and characteristics of a kidney mass.

Laboratory Testing

Blood and urine tests provide important information about kidney function and overall health.

Additional Evaluation

Depending on the imaging findings, a biopsy or other diagnostic tests may be recommended.

Personalized Treatment Options

Treating Kidney Cancer

Treatment depends on several factors, including the size, location, and stage of the tumor, as well as your overall health and kidney function.

Active Surveillance

Certain small kidney masses may be carefully monitored through regular imaging and follow-up appointments.

Partial Nephrectomy

A surgical procedure that removes the tumor while preserving as much healthy kidney tissue as possible.

Radical Nephrectomy

A surgical procedure that removes the affected kidney when necessary to treat the cancer.
