Today’s Headlines: Dementia Study, CT Scan Risks and Cancer Prevention

Later Retirement May Help Prevent Dementia: “New research boosts the “use it or lose it” theory about brainpower and staying mentally sharp. People who delay retirement have less risk of developing Alzheimer’s disease or other types of dementia, a study of nearly half a million people in France found. It’s by far the largest study to look at this, and researchers say the conclusion makes sense. Working tends to keep people physically active, socially connected and mentally challenged — all things known to help prevent mental decline.” (USA Today)

New Study Investigates the Risk of CT Scans and Pediatric Cancer: “The researchers estimate that one year’s CT scanning in the United States would produce 4,879 future cancers in children under 15 — a small but significant increase. The researchers calculate that if the highest doses — those in the top one-quarter — could be reduced to match the average dose, future cancers would be reduced by 43 percent.” (New York Times)

Research Says Aspirin May Prevent Cancer in Women: “Women who took low dose aspirin on alternate days for 18 years saw a 20 percent drop in their risk of developing colon cancer, according to the study published in the Annals of Internal Medicine. The new report, based on data from the Women’s Health Study, followed more than 30,000 women, half of whom were randomized to take aspirin every other day, while the other half received placebo treatments.” (NBC News)
