Abstract

A unique pair of identical twins were concordant for breast cancer, diabetes mellitus, nontoxic goiter, hypertension, cholecystitis, obesity, relaxed pelvic outlet, and myomata uteri. The medical literature for concordant breast cancer in identical twins is reviewed and there seems to be a strong tendency for these tumors to occur in the same breast and at the same time.
