“…Schettler (1966) reported multiple malignancies to be commonest in men. However, according to Becker (1966), Lohr and Huber (1961) and Schott and Walther (1966) multi‐malignant tumours prevail in females, and this view is supported by Fischer (1956) and Korger (1957). Because of the frequency with which breast carcinoma occurs concurrently with carcinoma of the uterus, ovary or Fallopian tubes it has been suggested there may be some hormonal influence common to both.…”
