Size isn't important; the Forrest Unit.

The early success of breast screening in the UK is encouraging, and has been achieved by cooperation between multidisciplinary teams working together in large screening units. Future market forces may serve to disintegrate this arrangement with the resulting emergence of smaller, self-sufficient units. Winchester's 'first round' screening results suggest that with appropriately trained team members, such units can provide a convenient, high quality local service without compromising cancer detection.
