Health Alert: One colonoscopy may be enough

(CBS) - People whose first colonoscopy comes back negative may not have to have another one. Currently, a colonoscopy is recommended every 10 years. But a new study in the "Annals of Internal Medicine" finds other kinds of follow ups -- including blood tests and CT scans – have the same survival rates with fewer complications and a lower cost. But other experts argue most people prefer to endure a colonoscopy and never have colorectal cancer, than to suffer with cancer and survive.

(CBS) - A new study out of Northwestern University finds more than half the population is at risk for cardiovascular disease at some point in their lives. The research shows even men and women who have no risk factors for the disease have a 30 percent chance of getting CVD in their lifetime. Cardiovascular disease includes heart attacks, heart failure and stroke.

(CBS) - The least experienced doctors spend the most amount of money, according to a new study. Researchers found that doctors with less than 10 years on the job spent 13 percent more treating patients than doctors with 40 or more years of experience. One possible explanation may be that recently trained doctors may be more familiar with expensive, new treatments. Another is that their lack of experience and uncertainty makes them order more tests.
