A technique for destroying breast tumours by freezing them with ice could offer hope of a safe non-surgical cure for the disease, a study suggests.

The technique called cryotherapy is already used to treat prostate cancer and involves inserting several needle-like 'cryoprobes' into the tumour and passing super-cold gas through them," reports dailymail.co.uk.
The ice ball rapidly created around each site kills off the cancerous cells. Freezing therapy has been tried before for breast cancer but this is the first time a minimally invasive version, which requires no surgery, has been developed.

Cancer experts, however, warned it may take many years for the technique to become common.
