In Switzerland, about 1000 new cases of kidney cancer are diagnosed each year. About 300 people die of kidney cancer every year.

Worldwide, there were an estimated 400,000 new cases of kidney cancer and 175,000 deaths from the disease in 2018.
By 2040, the number of new cases of kidney cancer is expected to increase to nearly 650,000 a year and the number of deaths to more than 300,000 a year.

Other risk factors include:
In many cases, the cause of kidney cancer is not known. In some other cases (such as with inherited conditions), even when the cause is known it may not be preventable. You may reduce the risk for developing kidney cancer by stopping to smoke and maintaining a healthy body weight.
