survival rates are a pretty bad metric because you can easily change them by changing the amount of screening without making people live longer or healthier. when you compare cancer mortality rates, the US is not doing well.

Nope. Certain types of cancer screening are helpful in making people live longer and healthier. It is much easier to treat cancer when it is caught early.

Absolutely, but 5 survival rates are still a really bad metric because they make things look better even for uncurable cancer (or cancer that was curable but treatment was given up on because of price). Also, if a 90 year old gets a slow growing cancer that doesn't require treatment (cause they'll be dead before it's a problem), screening for it will increase survival rates even though you didn't actually treat anything.
