What is Kidney Cancer?

Kidney cancer or Renal cell carcinomas (RCCs), which originate within the renal cortex, constitute 80 to 85 percent of primary kidney (renal) neoplasms. Transitional cell carcinomas of the renal pelvis are the next most common (approximately 8 percent). Other parenchymal epithelial tumors, such as oncocytomas, collecting duct tumors, and renal sarcomas, are rare.

Kidney Cancer Symptoms

Patients with kidney cancer or RCC can present with a range of symptoms; unfortunately, many patients are asymptomatic until the disease is advanced. At presentation, approximately 25 percent of individuals either have distant metastases or advanced locoregional disease.

Patients with localized disease can present with a wide array of symptoms and/or laboratory abnormalities, or they may be diagnosed incidentally.  The most common presenting symptoms were blood in the urine (hematuria), abdominal mass, pain, and weight loss.

Kidney Cancer Treatments

For patients with isolated, solid kidney masses, resection with either a partial or complete nephrectomy is preferred to biopsy because it provides both the diagnosis and definitive treatment.
