NHS is not bad on cancer treatment - but often dismal on diagnosing it early enough, that's thought to be key reason for poor UK cancer survival rates: Obviously the later a cancer is diagnosed, the less likely treatment will be (a lot more likely to succeed if cancer is confined to a tiny area and amenable to surgery, radiotherapy etc. compared to it having metastasized (spread around the body) and chemo being the only option left)
