BREAST cancers can be killed off by being frozen with streams of super-cold gas, scientists have discovered.
And, in a major breakthrough, the “ice-ball†created around a tumour by the injections not only kills it off but ensures the cancer does not return.
Fine needles are used to inject the freezing gas around the tumour in a technique known as cryotherapy, which means the patient does not need invasive surgery and suffers no major discomfort.
