Frequency and Distribution of Genital Cancer In the last decades the relative importance of cancer on the mortality rate in western countries has been steadily increasing. Cancer in these countries nowadays matches with circulatory diseases as the most frequent cause of death. There are however still relatively few accurate figures on the occurence of cancer. In Norway, with a female population of about 1, 7 million, we have since 1954 a central Cancer Registry. Cancer is by law a reportable disease. Every physician, pathological institute and hospital have the duty to notify the Registry of all new cases of cancer. The informations to be given include martial status, occupation, residence, duration of the symptoms, type and localization of the neoplasm. It is hoped that this accumulation of data will be able to reveal valuable informations on the epidemiology of the cancerous disease useful to the planning of the cancer campaign-and perhaps also provide some evidence which could give a suggestion as to the etiology of cancer. The average number of new cases of primary gential cancer annually in Norway are as follows. Cancer of the vulva and cancer of the vagina, taken together..............................50 cases. Cancer of the uterine body..........150 cases. Cancer of the adnexae................250 cases. Cancer of the uterine cervix........350 cases. These figures refer to cases of invasive cancer only. Precancerous lesions are excluded.
