Aspirin therapy: Study raises safety issues Many people take an aspirin a day to prevent heart attacks and strokes. But a major, new study published in the Jan. 9 online edition of the Archives of Internal Medicine says that might not be the right therapy for everyone, and might do more harm than good for some people. The research found that aspirin can cut heart attacks by 10 percent, but raise the risk of internal bleeding by 30 percent. Dr. Jon LaPook discussed the risks versus the benefits of aspirin therapy, and also explained who should be taking it and who doesn't really need it on "CBS This Morning." He also discussed a second study published Monday in the Archives of Internal Medicine that says statins -- cholesterol-lowering drugs that are one of the most widely prescribed drugs -- have a side effect that may increase some people's chances of developing Type 2 diabetes.
