Renal cell carcinoma (RCC), also known as renal cell cancer or renal cell adenocarcinoma, is the most common type of kidney cancer.
Secondly, can a tumor on the kidney be benign?
Although most kidney tumors are malignant and therefore cancerous, up to 20% are benign. Benign tumors do not spread to other parts of the body. Having no signs of spreading is important for deciding what treatments might be best for the tumor. The biggest risk factor for having a malignant small kidney tumor is age.
Furthermore, how can you tell if a kidney tumor is benign or malignant?
Ultrasound. Ultrasound can help find a kidney mass and show if it is solid or filled with fluid (kidney tumors are more likely to be solid). Different ultrasound patterns can also help doctors tell the difference between some types of benign and malignant kidney tumors.
