What this and many other similar situations argue for IMO are better blood screens for cancer biomarkers.

For it turns out even with early detection, metastasis has already happened. It's just that those metastasized cancer cells take a long time to grow.

I mean the doctor is right, but it sure sucks to be one of the people who really has cancer and you skipped the screening, no?
