Cervical cancer: Screening and prevention
Regular screening can prevent cervical cancer. But it can also lead to the discovery of abnormal tissue (dysplasia) that doesn't need to be treated.
Cervical cancer (medical term: cervical carcinoma) develops when cells at the opening of the cervix change and become abnormal. Abnormal tissue can be discovered through screening and then removed before it has a chance to possibly develop into cancer. So this type of screening can also be seen as a form of prevention. Since it was introduced in the 1970s, there has been a big drop in the number of women with cervical cancer.
