Obviously I wouldn't change anything about the way this was handled. To be honest, my proposal is mostly a concession. It is an attempt to reduce the number of unnecessary tests and biopsies, while still gathering more data about the things that are going on in your body. It doesn't supersede anything that you've described, so if you feel a lump, you would still follow exactly the same course of action that you've outlined.
There must be a way to collect more data and respond appropriately to aggressive and dangerous cancers, while still reducing the number of unnecessary tests and biopsies. This is obviously a very important problem to solve and will save millions of lives.
