Do kidney cysts mean I have kidney cancer?
No, a kidney cyst does not automatically indicate cancer. There are two types of kidney cysts: the “simple kidney cyst” and the “complex kidney cyst”. The simple kidney cyst produces no symptoms, causes no harm to the body, and will not develop into kidney cancer. A complex kidney cyst, on the other hand, has a low risk of developing into kidney cancer. A urologist and radiologist will monitor a complex kidney cyst to note changes over time and predict the chances of the cyst developing into cancer.
