Treatment options for stage 2 kidney cancer are usually localized since the cancer hasn't yet spread past the kidneys. The most common treatment for stage 2 kidney cancer is surgery. The type of surgery depends on the size of the tumor. In some cases, if the tumor is small, doctors may perform a partial nephrectomy, which involves removing the tumor and a small bit of nearby kidney tissue. In most cases of stage 2 kidney cancer, the tumor is larger and doctors must perform a nephrectomy, which involves removing the entire kidney.
If surgery can't be done for some reason, doctors may perform other procedures, including cryoablation (using a needle to freeze cancer cells) or radiofrequency ablation (using an electric current through a needle to kill cancer cells). In some cases, doctors may recommend arterial embolization, which involves blocking the kidney's blood flow in order to shrink the tumor. Clinical trials and other treatment options may be available, depending on each individual case. Talk with your doctor to determine what treatment options are best for you.
