A new study in the British Medical Journal reports that breast cancer screening has not played a direct part in the reductions of breast cancer mortality in recent years.
I can hear the breast cancer industry screaming already. No doubt the industry will make its followers wear extra pink and walk extra miles this fall to pay for damage control.
After reviewing the study it seems to be saying that screening mammograhy done every two years has no effect on mortality. At least one country had screening every three years. The size of the cancer at the time of detction is directly related to survival. Thus two year intervals may simply allow too much time for the cancer to progress.
