Doctors are now freezing cancerous tumors

Doctors at the Mayo Clinic in Minnesota are killing off cancerous tumors by freezing them.

The procedure, called cryo-ablation, was used on tumors that had spread to the lungs from other parts of the body.

Doctors use a probe to apply extreme cold, -148 degrees fahrenheit, to the tumor.

They said it killed cancer cells for at least three months without affecting healthy tissue.

This isn't a cure for cancer, but experts say it could help slow tumor growth.
