It is true that the big change in cancer treatment over the next decade will be specific treatment for those with particular DNA. We are hugely fortunate in the sense that we have the Wales cancer genetic centre—Nobel prize-winning knowledge. I’ve certainly been there and they are developing more tests as they come along. At the moment, of course, there are particular tests that are used. There are others that will develop over the course of time and make it far easier for treatment to be tailored to the individual. For example, there are some drugs that are known to be damaging to some people on a chance of 300, 400 or 500 to 1, but, until now, there have been no tests to make sure that a particular person is not one of those people who could be particularly badly affected by that drug. As these tests develop, more and more people will have the chance of a better outcome.
