title: [Age-related characteristics of breast invasive ductal carcinoma].
abstract: 377 patients aged 30 to 79 years who had breast carcinoma were examined to study the age-related features of tumor anaplasia. The degree of tumor anaplasia was studied, in primary nodules, less and more than 2.5 cm in diameter in patients of different ages. This index decreased with age. This may explain more a malignant course of the disease in young patients.
