The radiation from a CT scan, or computed tomography, actually has been shown to cause cancer - quite a bit of it. A recent report, published in November in the New England Journal of Medicine suggests that the radiation from current CT-scan use - estimated at more than 62 million...

CT was a huge plus: It could image so many things in the body that were difficult, painful or simply impossible to see otherwise - brain tumors, spine problems, problems in the liver or lung.

What's more, CT scans of patients' muscles suggested that exercise could improve their internal structure and function. "So, even if you're not losing weight, don't get discouraged just because of that," says Sigal. "There's still additional value [of exercise] independent of weight loss...
