What is Kidney Cancer?

Kidney cancer is that kind of cancer or tumour that emanates from the kidney and not from other organs into the kidney. Kidney is a gland that is situated one on either side of the vertebral column in the upper posterior abdominal cavity. Its main function is secretion of urine which flows into the uretes. It secrets renin and renal. There are Two types of kidney cancer: Renal cell carcinoma. This type originates from renal tubule. The other that emanates from tubule is the clear cell adenocarcinoma. Urethelial cell carcinoma of the renal pelvis. Other less common types of kidney cancer include squamous cell carcinoma, renal oncocytoma, renal lymphoma, transitional cell carcinoma. Wilms’ tumour is mostly common children below 5 years.

Kidney cancers are diagnosed throughout the world but they are more prevalent in Northern America and more less in Africa and Asian regions. It is common in men over 70 years although women above 65 years have also been diagnosed.

Kidney cancer can show signs or may not show any signs. The most common sign that normally occurs is a mass in the abdomen (it grows and fills the entire belly in extreme cases), hydronephrosis (distension of the kidney pelvis with urine, from obstructed outflow. If unrelieved,pressure eventually causes atrophy of kidney tissue).

Treatment for kidney cancer depends on the type and stage of the disease. In wilms tumor (in children), chemotherapy, radiotherapy and nephrectomy are the recommended treatments. In renal cell carcinoma, treatment depends on the stage of the cancer, but typically does not involve chemotherapy and radiotherapy, as renal cell carcinoma is resistant to these therapies. Treatment for localized renal cell carcinoma consists of nephrectomy alone, with no adjuvant (post surgical) therapy. In metastatic renal cell carcinoma, treatment the use of torisel, nexavar and sutent. Interferon and interleukin-2 are at times used.
