Doubtful health benefit of screening from 40 years of age

摘要

Results of the UK Age trial suggest a significant benefit of annual mammography initiated at 39-41 years of age in preventing breast-cancer deaths occurring before the age of 50 years; however, this approach had no effect on the risk of breast-cancer death occurring before the age of 60 years and leads to prolonged deteriorations in quality of life owing to overdiagnosis.
