These occur infrequently in males in developed countries,the incidence being about 1% of that in females. Two-thirds of patients present with intraductal carcinoma. The average age of onset is 60 years for men. Orchiectomy was the standard treatment but it has been replaced by TAMOXIFEN as the initial therapy since estrogen-receptor-positive tumors are predominant in males.
