瑞士并没有禁止mammography。这个消息来源应该是指前段时间瑞士的一个医学机构建议停止大规模mammography项目。这只是纯粹建议，并没有实际实施，而且在瑞士医学界引起了很大争议。

The Swiss Medical Board has recommended that Switzerland stop introducing new mammography screening programs and phase out existing programs, according to an essay published online April 16 in the New England Journal of Medicine.

The Swiss Medical Board is an independent health technology assessment initiative that is sanctioned by a number of the country's major medical bodies. Its recommendations are "not legally binding."
