Kidney cancer is increasing in Minnesota
Kidney cancer incidence has been increasing in Minnesota and nationally, though mortality has been stable. Kidney cancer is nearly twice as common in males as in females and is highest among Minnesotans that identify as American Indian. From 2016 to 2018, approximately 765 new cases of kidney cancer in males and 374 new cases in females were diagnosed in Minnesota residents each year.
Kidney cancer cases in Minnesota
Rates for males have seen an increase of 1.8% per year. There is some evidence that rates are decreasing in females but will likely need more years of data to affirm this. Most recently, the age-adjusted incidence rate of kidney cancer was 24.0 new cases per 100,000 males and 11.8 new cases per 100,000 females.
Kidney cancer cases in Minnesota, by age
The rate of kidney cancer increases with age. The highest incidence rates occur among adults aged 70-79 years, in both sexes.
Kidney cancer cases in Minnesota, by race/ethnicity
There are large differences in kidney cancer incidence between different racial and ethnic groups in Minnesota. From 2009 to 2018, the rate of kidney cancer was highest among American Indians (with about 36 new cases per 100,000 American Indians) and lowest among Asian/Pacific Islanders.
Kidney cancer starts in the tissues of the kidneys or renal pelvis (the top part of the ureter, a tube that connects each kidney to the bladder). Kidneys filter waste products out of your blood and produce urine. The most common type of kidney cancer is renal cell carcinoma, which accounts for 90% of kidney cancers.
What are risk factors for kidney cancer?
- Smoking causes approximately one-third to one-half of kidney cancers and increases risk for many other cancers as well.
- High blood pressure (hypertension) increases the risk of kidney cancer. It is not known whether the cancer is caused by drugs used to treat hypertension or by the hypertension itself.
- Race: kidney cancer is twice as common among American Indians compared to any of the other racial and ethnic groups.
- Occupational exposures: Occupationally-related risks for kidney cancer include exposure to certain dyes and organic solvents (such as trichloroethylene or TCE) as well as asbestos.
How can kidney cancer be prevented?
Don't smoke. Avoid tobacco smoke. Maintaining a healthy weight and diet will reduce the likelihood of both hypertension and kidney cancer. Avoid known occupational exposures that increase the risk of kidney cancer with long-term, intense doses.
