RELEVANCE OF DIAGNOSTICS AND TREATMENT OF BREAST CANCER IN MEN

Breast cancer in men is a rare disease, accounting for approximately 0.1% of all malignant breast tumors in men and from 0.6% to 1% of all malignant breast tumors. The incidence of breast cancer in men increases with age for unknown reasons: the average age of men at the time of diagnosis is 67 years, compared with women, whose similar indicator is 57 years. Despite advances in the diagnostics and treatment of breast cancer in women, understanding and strategy for the treatment of breast cancer in men are limited and generally extrapolated from existing knowledge about breast cancer in women. In particular, the molecular subtypes of breast cancer in men have not been studied, although these subtypes have been associated with both biological and clinical features of breast cancer in women. It has been proven that molecular subtypes have an important prognostic value in breast cancer in women. Molecular assessment of tumors plays a significant role in the 22 prescriptions of adjuvant chemotherapy, and therefore the role of genetic testing increases.
