MRI finds breast cancer before it becomes dangerous
A study in the Lancet (vol. 370, 11 August 2007) could lead to a change of paradigm in the early diagnosis of breast cancer. It states that magnetic resonance imaging (MRI) is substantially more accurate than mammography in diagnosing very early stages of breast cancer .
