Breast cancer in brothers: case reports and a review of 30 cases of male breast cancer

Cancer. 1975 Aug;36(2):458-61. doi: 10.1002/1097-0142(197508)36:2<458::aid-cncr2820360222>;2-v.


Two brothers with breast cancer are presented. One died 8 years after diagnosis and the other is presently living at 1 year with metastatic disease. The courses of 28 other previously unreported male patients with carcinoma of the breast are reviewed, and the possibility of male breast carcinoma being metastatic disease from the prostate is discussed. Useful etiologic information might be obtained from following the offspring of male breast cancer patients to see if they are at increased risk of developing the disease.
