The Day in Medicine
Published Date: 05-09-2008 01:29 PM CT
You know it's good for you to head to the gym and get in your exercise for the day...And it turns out, it's not just good for muscle tone in your arms and legs... it's good for muscle tone in your heart.Andrea Stassou has that story and more in today's health watch report.You might hit the gym to shape up your arms or chest but in the process you're sculpting a much more important muscle.Aerobic exercise can cause structural changes in the heart that make it easier to do its job.More study of how exercise directly affects the organ could point the way to tailored rehab recommendations for cardiac patients.5-percent of breast tumors appear to double in size in just over a month.Advocates say this is just another reason to encourage more frequent screening.Studies have provided conflicting evidence over whether mammograms save lives, but there's no question that breast cancer detected earlier is far easier to treat.The risks of developing Alzheimer's disease differ between the sexes.New research indicates men at the greatest danger are more likely to be overweight, diabetic, and to have had a stroke.Women at highest risk are more likely to be depressed or dis-abled, and in poorer general health.Those are some of today's top medical stories.I'm Andrea Stassou - CBS News - New York
