[Screening and diagnosis of cervical cancer].

The screening of cervical cancer is ideal. Performing its screening allows discovering early stage of invasive cancer but above all to diagnose numerous precursor lesions: their treatment carry out the prevention of invasive cancer. Without an organised screening in France, there is a spontaneous screening. Nevertheless the incidence of invasive cancer decreased twofold since twenty years. It remains unfortunately frequent. With a well organised mass screening its rate will probably decrease significantly.
