Zap Kidney Tumors without Surgery


Less Pain, Shorter Recovery

A new technique called radiofrequency ablation destroys cancerous kidney tumors with a needleshaped probe, guided into place by CAT scan equipment. After insertion, the probe opens up, wraps around the tumor, and emits radio frequency to heat the cancerous tissue to 105 Celsius, killing it. Compared with surgery, there's shorter recovery and less pain.

Only peripherally located kidney tumors smaller than 4 centimeters in diameter can be destroyed effectively with this procedure, says Jeffrey A. Cadeddu, MD, head of the urologic cancer treatment department at the University of Texas Southwestern Medical Center at Dallas. Radio frequency ablation is available at academic medical centers across the US. Your urologist can help you find the nearest location. Meanwhile, ablation is being tested for liver, bone, breast, and lung cancers.
