From an article on mammograms, and why they haven’t dropped the incidence of metastatic breast cancer:
Mammograms, it turns out, are not so great at detecting the most lethal forms of [breast cancers] a treatable phase. Aggressive tumors progress too quickly, often cropping up between mammograms. Even catching them “early,” while they are still small, can be too late: they have already metastasized. That may explain why there has been no decrease in the incidence of metastatic cancer since the introduction of screening.
At the other end of the spectrum, mammography readily finds tumors that could be equally treatable if found later by a woman or her doctor; it also finds those that are so slow-moving they might never metastasize. As improbable as it sounds, studies have suggested that about a quarter of screening-detected cancers might have gone away on their own.
