[Current controversy on the effectiveness of mammographic screening for breast cancer in western nations].
In 2000, Olsen and Gøtzsche raised doubt about the results of randomized controlled trials (RCT) on the effectiveness of mammography screening. The paper aroused much criticism, and on October 20, 2001, Olsen and Gøtzsche again published the results of meta-analysis on the effectiveness of screening for breast cancer using mammography. Their results suggested that there was no reliable evidence that mammography screening reduced mortality. Their article in 2001 created worldwide controversy on the effectiveness of screening for breast cancer using mammography. However, breast cancer mortality has declined after introducing the screening mammography in many Western nations, and the guidelines for breast cancer screening were not changed in the countries.
