Improving clinical breast examination training in a medical school: a randomized controlled trial.

To evaluate a new program for teaching clinical breast examination, a class of 156 second-year medical students were randomized into an experimental group (practice and feedback on silicone breast models and women volunteers) and a control group (lecture only). During a simulated practical clinical examination routinely conducted at the end of the second year, the experimental group students used more suggested palpation techniques during a patient examination (4.6 vs 2.0; p < 0.0001) and found more simulated lumps in a silicone model (4.7 vs 4.4; p < 0.05). Practice with immediate feedback is more effective than lecture alone in teaching clinical breast examination.
