The kidneys are piece of the body's urinary system, which filters squander products out of the blood in the shape of urine.

Over the 85 per cent of kidney cancers are renal cell carcinomas, which begin in the lining of one or both kidneys. Other types of kidney cancer comprise transitional cell carcinoma.
Concerning the kidneys
The kidneys are two bean-shaped organs situated on either side of the center of the back, just underneath the ribs. As well as filtering blood, the kidneys make three significant hormones:
- Renin - this hormone helps adjust your blood pressure.
- Calcitol - this hormone helps to manage your body's calcium levels.
- Erythropoietin - this hormone stimulates your bone marrow to create red blood cells.
Risks and causes of kidney cancer
The reasons of kidney cancer are unknown. However, there are several factors that may increase your risk including:
- Cigarette smoking - around one in three cases may be owing to smoking.
- Faulty genes - some people inherit faulty genes, which place them at a high risk of developing kidney cancer.
- Mild pain-killing drugs - such as overuse of painkillers containing phenacetin. This chemical is not used in latest painkillers. Though, people who took painkillers containing phenacetin in large quantities before it was banned may still be affected.
- Being overweight.
- Exposure to asbestos or cadmium - this applies to some people who were exposed to these substances in their jobs.
