It is a good news that there is technology to find out whether a anti-cancer drug can work on people or not by looking at their genes. As said by Dr Charles Swanton, treating only the patients that will benefit from certain treatments will save the NHS money in the long term. I agree with what he said. It can benefit the patients as more effective drugs can be given by knowing which drugs have no effect on which kind of patients. Although finding out patients genetic component in order to know whether a drug will work or not may cost a lot, if a simple diagnostic test can be developed later, this can no doubt can help the NHS to save money in the long term. Clearly it will be a win-win if more research can be done here. - Sharon Yim from Bookmarklet
