Breast self-awareness: the evidence behind the euphemism.

Breast cancer is the most common malignancy among women. Breast self-examination originally was proposed and implemented under the assumption that it would increase early detection and, theoretically, improve survival. However, breast self-examination since has been proven to have no effect on mortality from breast cancer. Rather than being abandoned, breast self-examination has been repackaged into the new concept of breast self-awareness. Although the desire to empower women with self-detection of cancer is noble, teaching techniques that have been proven not to be effective likely causes more harm than good.
