Sniffing Out Cancer With Electronic Noses 22

    The issue with mammograms is inappropriate mass screening; they're still a useful diagnostic tool, and have a benefit in routine screening in high-risk populations. If this device has the same false positive/negative rate as mammograms but is less intrusive and doesn't involve X-ray, that'd improve the benefits for those groups even futher.

    Now, there is a related issue that any more-convenient diagnostic tool runs an even higher risk of being overapplied.

A complex system that works is invariably found to have evolved from a simple system that works.
