...the??toughest things I do as a physician is deal with uncertainty. Doctors are often only as good as their diagnostic tests, and those tests aren't perfect. Too often we are forced to say, "You might have cancer"--which leads to lots of fear, anxiety and lost sleep. It is also often the beginning of an arduous process of more tests and in some cases surgical procedures. The only way to be absolutely sure about cancer is to examine some of the suspicious cells under a microscope. That means a biopsy. And in the U.S. we perform more than...
Bacon may be a staple of the??American breakfast, but it's probably not a terrific idea to eat it every day. Or sausage or corned-beef hash, for that matter. Researchers from the Karolinska Institute in Stockholm pooled data from 15 studies and found that eating just over an ounce of these smoked and processed delicacies each day increased the risk of developing stomach cancer from 15% to 38%. The culprit may be the high salt content of such meats, which could irritate the lining of the stomach, or perhaps the nitrate and nitrite additives, which are known...
...coffee destined to be the??next health food? Researchers found more evidence that drinking coffee--with or without caffeine--decreases the risk of Type 2 diabetes in those who are prone to develop the condition, perhaps by boosting the body's metabolism a bit. (Exercise is, of course, even more effective, but maybe you need that extra jolt to get yourself moving.) Coffee also seems to decrease slightly the risk of liver damage in patients with a history of alcoholism, perhaps because coffee contains lots of antioxidants. But the news isn't all good. Drinking lots of coffee during pregnancy...
People seeking the??heart-protective powers of omega-3 fatty acids in fish have been warned about the mercury, dioxins and PCBs that they might be consuming with their meal. But a study from the Harvard School of Public Health showed that while those contaminants pose a danger, particularly for women of childbearing age, for most people the benefits of fish outweigh the risks. Eat modest servings of fish each week--particularly salmon and bluefish--and you may reduce your risk of coronary heart disease 36%. Elsewhere, researchers at Louisiana State University reported that omega-3s can help protect cells...
Need a ride home for the??holidays? Hitchhiking may have fallen out of favor, but a new form of ride sharing has emerged to replace it on--where else?--the Web. Today tens of thousands of Americans go online every month to stick a virtual thumb out in cyberspace, especially during holiday travel seasons...
