The New York Times offers two stories examining medical advances for determining disease and injuries and whether that has improved health or just increased health costs.

The New York Times: Considering When It Might Be Best Not To Know About Cancer

The New York Times: Sports Medicine Said To Overuse A Popular Scan
M.R.I.'s can be invaluable in certain situations - finding serious problems like tumors or helping distinguish between competing diagnoses that fit a patient's history and symptoms.

But scans are easily misinterpreted and can result in misdiagnoses leading to unnecessary or even harmful treatments (Kolata, 10/28).
