Who's reading your mammogram could make a difference in your diagnosis. A new study finds physicians who've been reading mammograms for at least 25 years were more accurate than those with less experience. The study published in the National Cancer Institute found the more experienced physicians were more likely to properly identify cancer, and they were 50% less likely to miss cancer. Researchers conclude there is a need for more training and better ways to monitor the interpretation of those tests. Researchers say the doctors' ability to detect the cancer varied from 29% to 49%, but it was hard to predict who was the better mammogram reader. When they looked at the false positive rate, their was also a variety of results but the more experienced doctors clearly had fewer false positives.
A genetic discovery puts researchers one step closer to finding out what causes Alzheimer's disease. In two large study samples, researchers identified an altered version of a gene that increased the risk for late-onset Alzheimer's disease. The study in the New England Journal of Medicine found people with the altered gene had nearly twice the risk of developing Alzheimer's. Researchers say this puts them closer to understanding the disease and hopefully creating the right medicine to control it.
Holiday travelers may be faced with another sort of intestinal "revenge", the kind where you can't go! Dietitians from the University of Alabama at Birmingham say vacationers don't have to suffer in misery from constipation. Drinking plenty of water is a major key to recovery.
