What is the difference between clear cell renal cell carcinoma (ccRCC) and papillary renal cell carcinoma?

Clear cell and papillary renal cell carcinomas are types of kidney cancer that cause similar symptoms. Treatments are also similar. The main difference is how your kidney cancer cells look under the microscope. Papillary cancer cells resemble long, thin, finger-like growths. Healthcare providers call these growths papillae. About 1 in 10 people with renal cell carcinoma have the papillary type.
