The Internet provides a wealth of information on all aspects of health-related issues. A majority of patients now report that they seek health information on the Internet.

Reviewers continue to assess the accuracy of online healthcare information.

Researchers from Texas recently conducted a clinical study to evaluate the accuracy of information about breast cancer on the Internet. This study included 343 unique Web pages found from breast cancer-related queries entered on five search engines. Researchers also attempted to establish criteria to help identify inaccurate information on these pages.

  • There were no other identified criteria associated with inaccurate statements.
