An Alternative to Surgery for Kidney Cancer  
Patients with small kidney tumors sometimes require surgery, or nephrectomy, to remove malignant tissue. However, kidney tumor ablation offers a faster, easier alternative to surgery for some, allowing precise removal of the tumor while leaving as much of the kidney as possible.  

Kidney tumor ablation can help some patients avoid nephrectomy, the removal of a kidney. 

This minimally invasive procedure allows a radiologist to use imaging to apply extreme heat or cold to a tumor and destroy it instantly. Kidney tumor ablation is best for patients whose malignancy has not spread beyond the kidney and for whom surgery is not the best option for reasons of age or health condition. Most patients who undergo kidney tumor ablation return to normal activities in 24 hours.
