title: Increased incidence of breast carcinoma in patients with irradiation for post-partum mastitis: a screening situation.
abstract: In Rochester, New York, 606 women were treated with ionizing radiation for post-partum mastitis, mostly between 1940 and 1955. Two-thirds of all breasts were treated, the average dose per breast being 377 rads (at 2.5 cm breast depth). Mammographic examinations were performed on 265 of these women still residing in this vicinity. Two nonpalpable carcinomas (with no axillary node metastases) were found in the twelve breast lesions that have been biopsied. Some of the biopsies revealed premalignant changes. It is recommended that women in this high-risk category have close medical supervision, as well as periodic mammographic evaluation, and that the importance of periodic breast self-examinations should be emphasized.
