I had it on, intended to pay attention, but as usual was doing more than one thing at a time so just caught bits of it. (I really ought not do that, there's little enough on the box worth watching without missing something worthwhile.)
Bits I did see seemed to be covering stuff I was under the impression they were already doing. Radiating the tumour from different angles and such like. Maybe they're further behind than I figured.
Ultimately any new discovery is likely to be of benefit, the question is just one of when it'll work it's way down to the masses. When it's hardware I suspect it'll come in as soon as it is possible to do so, since an initial outlay makes it available to all patients. Drugs are likely to take longer IMO given that the budget needs to be justified, and that the NHS isn't just dealing with a single issue, a single medical problem. But once the patent (or whatever) runs out and the discoverer has made a pile, then it should be easier to get.
There is an issue with any reporting of science, and in particular medical science, in that the earlier some promising research is made known, the longer we all have to wait until it is cleared for use. But we all have to shuffle off this mortal coil with something, and at least we can hope that the next generation will have benefits we could not get, just as we had benefits previous generations did not.
