Computed tomography (CT or CAT) scans help doctors detect everything from cancer to kidney stones. But some physicians are raising concerns about the safety of such procedures - most notably, an increase in cancer risk. A CT scan packs a mega-dose of radiation - as much as 500 times that of a conventional X-ray. If your doctor orders a CT scan for you or your child, should you think twice...

...better the same day, and most improve within a week. About 20% see no progress at all, but the company hasn't received reports of negative effects and it says it didn't see any in its earlier clinical trials. Vet-Stem is now testing stem cells to treat kidney disease in cats and liver disease in dogs...

...much you are worth depends in a large part on which country you live in and your gender. In Iran, for example, you could legally sell your kidney for upwards of $6,000. Iran currently has no renal transplant waiting list, a credit to this policy legalizing the organ trade. In the U.S., where organ sales are illegal, the present waiting list of kidney transplant candidates numbers around 75,000. These individuals rely on the uncompensated charity of living organ donors, or, more commonly, the consenting donations of deceased persons. The average wait time is over five years and demand...

...commonly used argument against compensated kidney donation is that people in poverty would be most likely to sell their organs. While perhaps true, this concern neglects the fact that we already allow people with low-incomes to make their own decisions regarding the sale of their sperm, eggs and blood. Both kidney and egg donation are invasive procedures that come with associated risks. The decision whether or not to sell an organ would also not be made in a vacuum and one would expect medical professionals to fully present the associated (albeit minor) risks of kidney donation before surgery...

...Compensation to living kidney donors will save lives by increasing the supply of kidneys available for transplant—but most Americans probably value their kidneys at more than $6,000. Even more effective would be a system that allowed persons who consent to donate their organs upon death to bequeath their compensation. Currently only 35 percent of licensed drivers and ID card holders register to be organ donors. One would expect many more Americans to register if it meant that this would swell the inheritance they leave behind by several thousand dollars...
