Isn't this the idea behind watchful waiting? You have an early signal so you follow up with periodic tests to see if it goes away or shows signs of malignancy.

Isn't this the idea behind watchful waiting? You have an early signal so you follow up with periodic tests to see if it goes away or shows signs of malignancy. Eventually we'll have studies that show the conditional probability of different cancer outcomes based on these early signals, and from there we'll have a protocol to get the best outcomes, reducing the chance of malignant cancer while minimizing cost and medical intervention.
