Kidney cancer is the seventh most common cancer in the UK. In 2017, 12,615 cases of kidney cancer were diagnosed.*
Most people have two kidneys. They’re found on either side of your body just below the ribcage. Kidneys remove waste products from your blood and produce urine.
Kidney cancer usually affects only one kidney, but in rare cases it can develop in both kidneys.
There are several types of kidney cancer. The most common type is renal cell carcinoma, accounting for 80 per cent of kidney cancer cases.
There are many different reasons why kidney cancer develops, and this varies from person to person.
The good news is that you can make diet and lifestyle choices that can lower your risk of kidney cancer.
These steps are based on research from our Continuous Update Project (CUP).
Strong evidence shows that being overweight or obese is a cause of kidney cancer. Use our body mass index calculator to find out if you are a healthy weight for your height and visit our weight and cancer prevention page for tips to keep your weight healthy.
If you do smoke, stopping smoking will reduce your risk. The NHS stop smoking service can help you quit.
There is strong evidence that consuming up to two alcoholic drinks a day lowers the risk of developing kidney cancer. However, alcohol increases the risk of six common cancers and other diseases.
Scientists think that alcohol can directly damage DNA, increasing our risk of cancer. That’s why we advise not drinking alcohol at all. If you choose to drink, have no more than 14 units a week, spread over at least three days. Visit our alcohol and cancer prevention page to learn more.
