There is currently insufficient scientific data to support the recommendation to begin mammographic screening before the age of 50. The balance of the evidence that does exist suggests that screening before the age of 50 is useless and possibly harmful. If we accept that it is unethical to screen in the absence of good data suggesting benefit, then screening under the age of 50 is unethical.
目前尚无足够的科学数据支持在50岁之前开始进行乳房X光筛查的建议。现有证据的权衡表明，50岁之前进行筛查是无用的，甚至可能有害。如果我们认为在没有表明有益的充分数据的情况下进行筛查是不道德的，那么50岁以下进行筛查就是不道德的。
