| Abstract: | Comparative investigations of the urinary excretion of different 17-ketosteroids in healthy women and patients suffering from mastopathia fibrocystica and/or mammary carcinomas had the following results: 1. A clear age dependency of the excretion of 17 ketosteroids during the regenerative period has been shown in all groups investigated, but it could not be observed during the postmenopausal phase. 2. There are no hints by the excretion values for a remarkable contribution of mammary carcinomas to the hormone metabolism of the host. 3. The excretion values of patients suffering from mastopathia fibrocystica confirm epidemiological results, which consider this from of mastopathia a precancerous one. |
