This is a really neat and elegant study. All they're missing is a long-term survival curve.<p>You're probably wondering what the catch is if you haven't spotted it yet.<p>Ethanol ablation is usually used for carcinomas of the liver, although it sometimes sees use in some very rare cancers. So, this falls under the "extremely effective but with limited application" category. That doesn't mean it doesn't have great value, but you also don't want folk to think it's a "lethal injection for <i>all</i> tumours".
