Serious Warning Signs Of Kidney Cancer

The kidneys are located in the upper back region on either side of the spine. Adrenal glands sit on top of the kidneys and are both encapsulated along with fat inside of a fibrous layer called Gerota's fascia. Kidneys filter the blood of waste products, salt, and excess water. Kidneys produce hormones that influence blood pressure, red blood cell production, and electrolyte regulation. Kidney cancer is a malignancy that originates in the kidney tissues. The most common form of kidney cancer is renal cell carcinoma. Transitional cell carcinoma is a kidney cancer that begins in the renal pelvis lining or tissue where the ureters merge into the kidneys. Wilms' tumor is a kidney cancer almost exclusive to children. A renal sarcoma is a rare malignancy that originates in the connective tissues or blood vessels of the kidney.
