[Breast cancer in man]

Mortality from carcinoma of the breast in man varied from 0.6 to 0.8 per 100,000 from 1950 to 1970. Over the same period the equivalent figures in women were 22 to 29 per 100,000. From 1955 to 1968, the Enquête Permanente Cancer recorded 537 cases of carcinoma of the breast in men. 293 of which were seen before any treatment. This last group is described with respect to the age of the patient, the topography of the tumour, the histology, the tumor node metastasis and treatment. Survival rates were as follows: 39.2% at 5 years, 23.7% at 10 years and 16% at 20 years. The relative survival was 49% at 5 years, 37.5% at 10 years and 43.8% at 20 years. These results are identical to those published for numerically similar series. In this enquiry, a comparison between the results of carcinoma of the breast in men and women showed no difference.
