Cryotherapy boosts cancer-killing drugs:

Freezing tumour cells with cold metallic probes can boost the effects of cancer-killing drugs, say researchers. The technique, called cryotherapy, makes the tumour cell membranes become "leaky", which aids the entry of large molecules, such as drugs. Treatment with freezing alone left around 250 surviving cells - enough to form a new tumour - whereas the combination of freezing and delivering a drug left on average less than one cancer cell alive, report the researchers from France and the US. The study appears in the British Journal of Cancer (May 14).
