Help in fight against esophageal cancer?

A new treatment called "Cryospray Ablation", which can freeze and destroy cancer cells, may help people avoid this rare form of cancer.

The device unveiled Tuesday at Loyola University Medical Center works by spraying liquid nitrogen into the esophagus to freeze and destroy pre-cancerous cells.

The idea is to kill the abnormal cells before they become cancerous.

The Loyola University Medical Center says this technique is less painful than other procedures.

Another treatment, called Radio Frequency Ablation, uses intense bursts of heat compared to surgery. Doctors say either procedure can be easier on the patient.
