title: [Usefulness of detection of breast cancer: the part played by the internist].
abstract: The prognosis of breast cancer is the result of many factors, among which the mass of the tumor at the time of diagnosis remains the most significant: small tumors have a better prognosis than larger ones and are less often accompanied by positive lymph nodes. It is therefore justifiable to search for them systematically by breast examination of all patients over 30. Large-scale mass screening campains in the USA, with clinical and mammographic examination of tens of thousands of women, have proven that it is possible to detect more "early" cancers and reduce general mortality in the groups studied. The number of cancers thus detected is nevertheless so small that it does not justify the investment of so much labour and money in this kind of campaign. Systematic breast examination at regular intervals (6 months to 1 year) with regular mammographies should be confined to patients in the high risk groups: women who have already undergone surgery for cancer of one breast, and patients with a marked family history of breast cancer. For the rest of the female population, the solution seems obvious: every physician should get into the habit of performing regular clinical examination of the breasts. Most gynecologists are already doing so, but they only examine a small part of the population. The most important role in the detection of breast cancer falls to the internists and the general practitioners: they should assume responsibility for all their patients' breasts, in the same manner as they do for heart and lung examinations. They will then request additional examinations (mammography, thermography) as soon as clinical examination reveals a pathological finding. The results of GILBERTSEN [5] confirm that clinical examination remains the most valuable and least expensive method for breast cancer detection.
