[Epidemiology of mastocarcinoma (author's transl)]

Epidemiological examination of female patients with mastocarcinoma yields distinct differences in the rate of incidence among different groups of patients. In the industrial countries of the West, mastocarcinoma is 8 to 10 times more frequent than in the Far East and in some developing countries. In all groups under investigation, late primiparae are at an increased risk. Other risk factors are: previous familial history of mastocarcinoma, nulliparousness, women after a treated mastocarcinoma, as well as women with proliferating mastopathy. The setting up of risk groups enabled better on-target focussing of preliminary-care examinations.
