'Survival' for cancer tends to be defined as surviving 5 years. The earlier you catch, the more patient had left to live anyway.
The basic good old medical care invented 100 years ago, while dizzying amounts are spent on prolonging lives for very, very few years, often very late in life - efforts that are very close to - in effect to have done nothing, ie. almost performative.
Is this true?
I’m not sure what you mean by “very, very few years”. As a hypothetical would prolonging life for ~3-7 years in a 40-50 year old be considered “almost performative” to you?
“Good old medical care” often means 3-6 month survival for these patients.
there's probably no way to actually do anything concerted about it without turning society into Logan's Run but having gone through it with a grandparent and a parent, it is clear something is broken at the end of life
So yes, it's true (although that includes the cost of hospital stays which is where a lot of people end their life).
My grandma had a melanoma at the age of 74, which is "old" by most human standards. It was located on her earlobe and an operation helped her get rid of it.
She then lived to be 90, most of that extra time either fully or partially self-sufficient. Only in the last months in her life she really deteriorated.
Basically, she gained almost a fifth of her life by that single operation performed when she was already old.
