Israeli Technology Turns Tumors Into Ice Balls To Cure Cancer
Breast cancer patients could be treated without surgery following the development of a technique that destroys tumors by turning them into a ball of ice. Doctors have begun treating women suffering from breast cancer in trials of the device, which uses a supercooled needle tip to repeatedly freeze then defrost tumors so that the harmful tissue is damaged and ultimately dies.

The technique, which does not require general anesthetic and can be completed in about 15 minutes, could provide an alternative to surgery, which often requires women to stay in hospital for up to a week and can leave them with scars.

The needle is cooled to -274F (-170C) by pumping liquid nitrogen through a network of tiny tubes, allowing the surgeon to control the size of ice ball produced to ensure it freezes the entire tumor.

Scientists behind the device say it is possible to treat tumors up to the size of a golf ball. It has already been used on benign tumors and doctors have now begun a trial of the procedure in 30 breast cancer patients.
