Around 208,500 new cases of<unk>  are diagnosed in the world each year, accounting for just under 2% of all cancers. The highest rates are recorded in North America and the lowest rates in Asia and Africa. Lifestyle Risk Factors Certain lifestyle factors have been associated with the development of renal cancer, although not all of them can be considered definitive causes. These include smoking, chemical carcinogens, radiation, viruses, diet and obesity, hypertension, diuretics, and alcohol consumption. Only a small percentage of<unk>  cases have been linked to genetic factors. With obesity listed as one of the risk factors, daily physical activity and engaging in a healthy diet is proven to lower the rates of developing<unk>  in the future. Age The incidence rate of renal cancer increases with the age of an individual, with 75 being the approximate age of the peak incidence rate, as of 2018. However, nearly one half of all cases are diagnosed before the age of 65. In both male and female children, renal tumors represent 2% to 6% of<unk> , with Wilms' tumor being the most popular. Sex The incidence of<unk>  is two times greater in men than in women, and this is thought to be due to biological differences. Mortality rates typically decrease more rapidly in women compared to men. International Variations Incidence rates of<unk>  can vary throughout the world. As of 2018, Czech Republic and Lithuania have the highest incidence rate of<unk>  worldwide, with an age-standardized rate of 21.9/100,000 in males (Czech Republic) and 18.7/100,000 in males (Lithuania.) China, Thailand, and African countries (low-risk countries) have an incidence rate that is less than 2/100,000. Since the early 2000s, Austria and Poland have been the only countries to report a decrease in<unk>  rates. Diagnosis access bias plays a large role in the epidemiology of<unk> . Differences in<unk>  diagnosis across regions are likely due to differences in healthcare access, rather than a population's biological factors. Discrepancies in<unk>  diagnosis has most likely led to the underrepresentation of mortality and incidence in low income countries. Race Race and ethnicity may be a factor in the distribution of<unk>  around the United States. There are higher incidence rates in Black men and Hispanics, an average rate for American Indians, and low rates in Asians in the United States. Black people with<unk>  have lower mortality rates than Caucasians in the United States. Screening Accessibility for cancer screening is not very common due to high expenses. Improving cancer registries can improve care to those who have<unk>  as well as decreasing the incidence and death rates. Safe and dependable treatment is key with the screening and treatment, which is not always the case in many developing nations. United States The United States' NIH estimates for 2013 around 64,770 new cases of<unk>  and 13,570 deaths from the disease. The incidence of<unk>  is also increasing in the United States. This is thought to be a real increase, not only due to changes in the way the disease is diagnosed. Europe The most recent estimates of incidence of<unk>  suggest that there are 63,300 new cases annually in the EU25. In Europe,<unk>  accounts for nearly 3% of all cancer cases.<unk>  is the eighth most common cancer in the UK (around 10,100 people were diagnosed with the disease in 2011), and it is the fourteenth most common cause of cancer death (around 4,300 people died in 2012).
