The purpose of this review article is to propose the basic rules of a scientifically correct breast cancer mass screening. It might give to the different authorities arguments to make a choice between an organized screening and some trials currently used in our country.

The goal of the mass screening of breast cancer undertaken under the authority of the Province of Liège is to focus the action on rural communities. For this reason, mobile vans equipped with X-Ray dedicated units are used. The main difficulty of this programme is to reach a massive participation of the population. It varies up to now from 45% to 20% in the different visited villages. During the 42 first months of functioning, 16,207 mammographies were carried out in women aged from 40 to 69; 69 cancers were discovered in apparently healthy women plus 10 cases of epithelial hyperplasia with atypias. These first results are quite encouraging. The main task of this continuing programme will be to reach a better participation of the population.
The macroscopic anatomy of the breast is often not well understood; it is the reason why the radiologic images formation of this organ needs to be explained. This work is based upon anatomical-radiological confrontations, which allow to separate the two main compartments of the gland, the fibroglandular tissue and the adipose tissue, and to study the limits of these two components. Their different proportions are at the origin of different patterns leading to a simple classification of non-pathologic breast X-rays. This classification makes easier the diagnosis of abnormalities, especially of tumoral origin.

The authors invited eminent Belgian specialists to report on their experience in esophageal cancer. A summary is given of the most striking features of their reports.
The rationale and results of breast mass screening are presented. The data available suggest that annual or biannual mammography reduce breast cancer mortality and should be recommended especially to women aged 50-65.

The recent development of new imaging procedures has lead the radiologists to assessing the diagnostic efficacy of the available examination techniques in order to reduce medical care costs. In cooperation with epidemiologists and statisticians, several methods of statistic analysis of the diagnostic efficacy of the procedures such as sensitivity and specificity evaluation, ROC analysis, disease prevalence, predictive value of tests, etc... have been developed. Benefit-cost and cost-efficiency analyses have also been performed, with a view to improving the quality of long-term medical care for the patient at a lower cost both for himself and the society.
The authors summarize the most important conclusions of a multicentric multidisciplinary review on rectal cancer in Belgium.
During the last decade, the hypothetical carcinogenic effects of mammography have lead to new technical developments in X-ray diagnosis and to the use of other imaging techniques such as ultrasonography (US), transillumination, magnetic resonance imaging (MRI). Many preliminary studies were published but few clinical trials are really convincing. According to the definition of a diagnostic tool, none of these new modalities is supposed to supplant mammography in the diagnosis of breast cancer. Improvements are expected by digital mammography in the near future.
