CT scans are valuable for finding cancers, but deliver a lot of radiation in the process. That's an especially big concern for children.
Full body CT scans can save lives by helping detect cancer early. But the scans use high doses of radiation to create their detailed images, which means they also increase patients' risk of developing cancer later on in life.
Children and teenagers are at greatest risk, because they tend to live long enough to develop secondary cancers. And their growing tissues may be more susceptible to radiation.
Would a doctor dressing neatly affect your rating?
If you're looking to go out for dinner, see a movie or plunk down big bucks on a new TV, chances are you'll look online for help with the decision.
Lots of people are now checking out potential doctors that way, too. Online ratings are becoming part of how many Americans shop for a physician, according to a study in the latest issue of JAMA, the journal of the American Medical Association.

For someone with a serious injury, it's not just a matter of getting in the door at the <em>closest</em> hospital, but getting in the door at the <em>right</em> hospital, says Dr. Arthur Kellermann, an emergency medicine specialist.
When private hospitals transfer patients who don't have insurance to public hospitals, it's called "patient dumping." But a study from Stanford University published Wednesday suggests a twist: Hospitals, it seems, are less likely to transfer critically injured patients to trauma centers if the patients have health insurance.

Sure, it's relaxing. But all those hours on the sofa may make it hard to actually stand up on your own.
The more you sit, the less physically active you are, which can lead to all sorts of health problems, including an early death.
But too much sitting increasingly looks like a health risk all its own. Researchers at Northwestern University say that for people 60 and older, each additional hour a day spent sitting increases the risk of becoming physically disabled by about 50 percent — no matter how much exercise they get.
