I think it can one day. We seem to be gradually unpicking it and finding out that cancer is a mixture of separate things. For example we now know that breast cancer is not one thing, actually there are several cancers that can cause breast tissue tumours and one or two of them respond to medication very well. I think we will gradually work out a whole category of cancers and understand how they hurt us, and will then know how to target them best. Already people live for much longer than they would have done with many cancers. Like most people I have relatives who died from different cancers and I hope one day it will be a disease only in the history books
