Kidney Cancer  (Renal Cancer)

Your kidneys are two bean-shaped organs located in the right and left side in the posterior part of your abdominal cavity, below your rib cage. Each kidney is equipped with an excretory canal called ureter, which descends vertically in your retroperitoneal region (anatomical space behind your abdominal cavity), then in the pelvis to go into your bladder. The kidneys play major roles in your body; they are responsible for many vital functions including purification and secreting urine.  However, the kidneys may be affectedby many disorders, among which cancer.

Kidney cancer, also called renal cancer, is a malignant tumor that develops in your kidney tissue. A kidney cancer can be primary; the cancer begins directly in the cells of the kidney. The same, the cancer can be a metastasis from a primary cancer of another organ that has migrated into your kidney; in this case, the tumor is called secondary kidney cancer.
