Can kidney tumor be removed?
Most kidney tumors and kidney cancer are cured with surgery. Surgery involves removing the entire tumor in the safest manner for each patient, and can be performed through a variety of approaches including a more traditional open incision, laparoscopic surgery or robot-assisted laparoscopic surgery.
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.
