It is well established that more MRI lead to more procedures that are ultimately themselves risky and useless. This is extremely difficult to parse out on an individual level but obvious in the data at a population level.
Colonoscopies are a great example. As their use increases past a threshold more people are injured by additional surgery than you actually help. This is again at a population level.
Beyond a certain point all scans will produce more unnecessary procedures than beneficial ones. It's the nature of treating illnesses with uncertain presentations. Everyone has lots of odd bits and small benign tumors that are harmless. But these often look indistinguishable from the early stages of something serious. Even biopsy isn't without risk.
