The age composition of women and structure diseases of mammary gland according to the biopsy research
Abstract
Studied data on occurrence rate, age composition of female patients, and structure of mammary gland diseases based on examination of biopsy samples (3380 bioptic mammary gland specimens). To determine histological forms of tumors, the WHO classification (2012) was used. As a result of the research performed, the prevalence of benign tumor diseases in the structure of mammary gland pathology (71 %) was has been detected. The age group of 50 to 69 years has accounted for the majority of malignant neoplasms in mammary glands (56 %). In the female age group of 20 to 49 years, prevalence of benign tumors has been observed. The average age of female patients with precancerous breast diseases has been 44.9 ± 13.7 years. The most common histological type among malignant breast tumors was nonspecific invasive carcinoma (89 %) and among benign tumors fibroadenoma (71 %).
