These, if spread over the suggested period of 20 years for the development of the disease, would present at the rate of 21 cases every year-thatt is, precisely at the known annual incidence. It is therefore necessary for all the detected preclinical cases to progress to clinical cancer, if left untreated, to produce the expected number of clinical cases each year. The incidence of the disease has dropped in screened populations, both here2 and

In a disease with a 10-20 year latent period between the preclinical stage and death time must elapse until the results of screening can be reflected in mortality rates. As we have sa-id,2 and as has Way,4 efforts must be concentrated on encouraging the screening of women of all ages. In Aberdeen young women are screened antenatally, their names put on a computerized register, and they are automatically recalled for screening at five-yearly intervals. T~he older women are screened in co-operation with their own general practitioners, and may be recalled at shorter intervals.-I am, etc., J.
