[Malignant tumors preceding or following breast cancer].

Using the records of the Cancer Clinic of Biella Hospital that date back more than 25 years, a retrospective survey was conducted into 65 patients suffering from two primary malignant neoplasms one of which affected the breast. Graphs and tables illustrate; the frequency, location, histological type, staging, the age of the patient and the date of the onset of the first neoplasia, any previous family history of cancer, the interval between the two neoplasias and the type of treatment given during this interval. Particular attention is paid to cases in which both neoplasias were breast tumours, and brief remarks on certain aspects of such cases are presented.
