title: [Cancer screening. Concepts, trends, and practices].
abstract: A National Cancer Surveillance Program has begun in Portugal in 1990. However, it is unevenly applied throughout the country and is almost unknown to clinicians other than general practitioners. As potentially life-saving procedures, cancer screening and early detection have an important impact not only among physicians but also among the general public, making it absolutely necessary an harmony of rationale, guidelines and practices. The author summarizes the points in discussion concerning cancer prevention procedures, the different published guidelines and some numbers on its practices. The aim is a contribution to an improvement in cancer screening in Portugal, achievable through awareness, promotion of evidence evaluation and the pursuit of consensus in strategies.
