In some countries cervical screening has been established for many years and has had a considerable impact on mortality from invasive cervical cancer. Because of this success, and in view of the continued high incidence and mortality from cancers generally, there is much interest in extending screening for other types of cancer. One example is the more recent introduction of mammographic breast screening in the UK. For other cancers, such as those of the colon, rectum, prostate and ovary, screening is currently confined to demonstration projects. Much of the success of cervical screening is attributable to the fact that abnormalities are detectable at a pre-cancerous stage, and treatment is effective in halting progression to invasive cancer. This is not always the case for most other forms of cancer screening.
在一些国家，子宫颈癌筛查已经开展多年，对浸润性子宫颈癌的死亡率产生了相当大的影响。鉴于这一成功，并且考虑到总体上癌症的高发病率和死亡率持续存在，人们对扩大其他类型癌症的筛查兴趣浓厚。一个例子是英国最近引入的乳腺钼靶筛查。对于其他癌症，如结肠癌、直肠癌、前列腺癌和卵巢癌，筛查目前仅限于示范项目。子宫颈癌筛查的成功很大程度上归因于在癌前阶段能够检测到异常，并且治疗能够有效地阻止进展为浸润性癌症。而大多数其他形式的癌症筛查情况并非总是如此。
