There's a new weapon out there against metastese to the liver from colon cancer and for liver primary tumors.  In the past, those who weren't eligible for liver resection had several options open to them, one of which was radio frequency ablation (rfa) which used radio frequency to kill the tumors from the inside out.  The problem was, the cells at the margin often survived and caused recurrence.

Now there's a new treatment called Covidien Evident Microwave Ablation that uses microwaves to heat the tumors in a similar manner to RFA.  BUT the procedure is more effective, according to a study, at killing cells at the margin, leading to few recurrences.

Here's a link to the article.  One more weapon, folks!
