Kidney New Cases

An estimated 65,150 new cases of kidney (renal) cancer are expected to be diagnosed in 2013. This estimate includes cancers of the renal pelvis (6%) and Wilms tumor (1%), a childhood cancer that usually develops before age 5. From 2005 to 2009, kidney cancer incidence rates increased by 3.1% per year, primarily due to an increase in early stage disease. Some of the increase in kidney cancer rates, paticularly for early stage disease, may be due to incidental diagnosis during abdominal imaging performed for unrelated issues. Based on the most recent years of data, it appears as though the rate may be reaching a plateau after several decades of increase.source:American Cancer Society. Cancer Facts & Figures 2013.
