A review of several studies by researchers at the
Cochrane Collaboration suggests that breast self-exams may be doing more harm
than good among women.
The review also included two large studies involving nearly 400,000 women in Russia and China. It found that rather than reducing breast cancer deaths, the emphasis on breast self-exams was actually increasing the number of unnecessary biopsies and scans.
In women who carried out self-exams, 3,406 had to have biopsies as compared to 1,856 among women not carrying out the checks.
