"Half (50%) of people diagnosed with cancer in England and Wales survive their disease for ten years or more" [0]
Since lots of cancers and lots of deaths are in old people, 10 year survival is quite a high bar.

Lumping all forms of cancer together is misleading, because cancers have dramatically different mortality rates. You need to separate by type of cancer, or else you're really just measuring the relative prevalence of different cancers.
As it turns out, the UK has a relatively low survival rate of cancers compared to other developed countries, including the US.

I get that this explanation fits with a common preconception of the US, but it doesn't bear out in reality. The US has a higher survival rate for all common types of cancer than all other developed countries, and this has been consistently the case for the last three decades.
