Kidney Cancer Symptoms

The Kidneys are paired organs located on either side of the spine in the lower abdomen. They are bean-shaped organs about 4.5 inches long, about the size of a fist, and each kidney weighs about 4 to 5 ounces.

Kidneys have several functions. The functional cell of the kidney is called nephron. Nephrons filter the blood to remove toxins, waste chemicals and water. This filtered fluid is then concentrated to form urine. The urine passes out into the ureters (connecting pipes) to be stored in the bladder and excreted by micturation.

Kidney Cancer: Cancer that forms in tissues of the kidneys is called kidney cancer. There are two types of kidney cancer: Renal cell carcinoma and Renal pelvis carcinoma. Cancer that forms in the lining of nephrons is called renal cell carcinoma and the cancer that forms in the center of the kidney where urine collects is called renal pelvis carcinoma. Renal cell carcinoma is the common type of kidney cancer.

Here are few symptoms of kidney cancer:

  • Blood in the urine, also called hematuria: This is the classic symptom of kidney cancer that occurs almost 60% of the cases. The urine appears slightly rusty to deep red in color. This blood loss also leads to anemia symptoms.
