Your kidneys are two bean-shaped organs, each about the size of your fist. They are located behind your abdominal organs, one on each side of your spine. Like other major organs in the body, the kidneys can sometimes develop cancer. In adults, the most common type of kidney cancer is renal cell carcinoma, which begins in the cells that line the small tubes within your kidneys. The American Cancer Society estimates that almost 51,000 people in the United States are diagnosed with kidney cancer each year. The incidence of kidney cancer seems to be increasing, though it isn’t clear why. Many kidney cancers are detected during procedures for other diseases or conditions. Imaging techniques, such as Renal Ultrasounds or CAT Scans of the Abdomen (CT), are being used more often, which may help find more kidney cancers. If a Kidney Cancer is diagnosed numerous treatments options are available. Kidney Sparing Surgery or Nephrectomies can be performed Laparoscopically or Robotically. Cryosurgery, Radio Frequency Ablation, and observation are other options also available.
